COMMON SYMPTOMS AND POSSIBLE CAUSESS Y M P T O M F U N G U S B A C T E R I A V I R U S N E M A T O D E P H Y T O P L A S M A I N S E C T / M I T E
Wilt YES. A number of well known
types are involved e.g.
Fusarium, Verticillium
YES. Bacterial wilt (Ralstonia
solanacearum) is a common
disease on many crops
YES. Tomato and pineapple
diseases exhibit, but not a
common symptom
YES. Nematodes frequently
attack the roots of a plant
and this causes wilting
NO. YES. – results of insect feeding
and also injection of toxins by
sucking insects
Leaf spot YES. Many types involved and
wide variety of shapes and
appearance
YES. Common symptom but
with distinct characteristics e.g.
water-soaking
YES. Quite common but less
distinct than most fungal leaf
spots
NO (NO) Leaf markings do occur but
generally not distinctive
YES. But not true leaf spots,
more the effect of feeding.
Canker YES. Cells are killed in stems,
including trunks of large trees.
YES. Canker is applied in a
slightly different way to fungal
cankers.
NO (NO) Some root lesions may
be described as cankers, but
this is a loose description
NO NO
Mosaic NO. Not a symptom which
suggests fungal attack.
NO YES Note that other factors can
produced similar symptoms
NO NO (YES) But symptoms are
superficial and different from
virus diseases
Yellowing of foliage (leaves) YES. Often indicates symptoms
or infection in other parts of
plant e.g. roots, cankers on
stem
YES. A general or non-specific
symptom noting general decline
of plant
YES. Distinctive feature but not
always easy to interpret. May
occur without obvious decline
of plant
YES. A general or non-
specific symptom noting
general decline of plant
YES. Distinctive feature but not
always easy to interpret. May
occur without obvious decline of
plant
YES General symptom, often
indistinctive
Witches’ broom
(many branches)
YES. Not so common, but be
careful to consider this
possibility
NO NO NO YES. Very distinctive feature but
sometimes not so clear – depends
on host response
YES Beware of mite damage.
Normal growth is disturbed by
feeding
Distortion of leaves YES. Some well-known
examples are distinctive, but
others much less so
NO YES. Distinctive feature,
though needs training to
identify clearly in field
(NO) General symptom in
most diseases, mostly the
affect of decline in whole
plant
YES. Distinctive feature, but note
that may only be present at
YES Aphid feeding in
particular. Can be distinctive,
though training needed to
separate from viruses (e.g.)
Reduction in size of leaves (NO) More the general effect of
reduced growth
(NO) More the general effect of
reduced growth
(YES) Rare symptom more
indicative of phytoplasmas; the
two groups share other types of
induced symptoms
NO YES. Distinctive feature, even
more so than viruses. The two
causes can be difficult to
distinguish in the field
NO Generally not a feature but
see note on witches’ brooms
and mites
Galls YES. More common on woody
plants
YES. Stimulate extra growth on
all parts of the plants
(YES) Conditions such ‘vein
enation’ are unusual and on
only a few crops.
YES. Typical swellings
appear on root, as well as
general distortion of root
systems
NO YES Many of the spectacular
and distinctive types are
associated with mites

characteristic symptoms of:
causing “dead heart” or drying of the central whorl of leaf during
the tillering stage. If the attack occurs during panicle formation or
heading stage then “white ear heads” are formed and the whole
panicle becomes chafead heart White Ear head

Cultural Practices:
Selection of healthy seeds or resistance /tolerance variety
Raising of healthy Nursery
Early and timely sowing/planting
Seedling root dip/Nursery treatment in stem borer endemic area
Destruction of left over nursery
Normal spacing
Balance use of fertilizer
Proper water management (Alternate wetting and drying to avoid water
stagnation in plant hopper endemic area)
Harvest close to ground
 Collection of egg masses and larvae of pest to be placed in bamboo cages
for conservation of biocontrol agents.
 Removal and destruction (burn) of diseased/pest infested plant parts.
 Clipping of rice seedlings tips at the time of transplanting to minimize
carryover of rice hispa, case worm and stem borer infestation from seed
bed to the transplanted fields.
 Use of coir rope in rice crop for dislodging case worm, cut worm and
swarming caterpillar and leaf folder larvae etc. on to kerosinized water (1
L of kerosene mixed on 25 kg soil and broadcast in 1 ha).
Mechanical Practices
The other borers are:
• Pink stem borer, Sesamia inferens - occurring mostly in rice-
wheat cropping systems of north-west India.
• White stem borer, Scirpophaga innotata - common in
southern regions particularly in Kerala,
• Dark headed stem borer, Chilo polychrysus and
• Striped stem borer, Chilo suppressalis in eastern and north
eastern states of West Bengal and Assam, respectively.
Management:
Cultural practices:
 Clipping of seedling before transplanting for prevention egg laying
 Harvesting done at the base of plant in order to avoid pupae remain in the field.
 Avoid high dose fertilizer.
Biological control:
 Five to six releases of the egg parasitoid Trichogramma japonicum @1,00,000 adult parasites per
hectare starting from 15 days after planting, in a crop season is effective and economical.
Chemical control:
 ETL:5-10% dead heart, 5% chaffy earhead per square meter 1 adult/egg mass
 Field sowing more then 5 % dead heart should be spread with 0.07% Phospomidon 30 EC (2.3
ml/liter water) or 0.15% Chlorpyriphos 20 EC (7.5 ml/liter water) or 7.5 kg Phorate 10G/ ha.
Biological Control Practices:
Conservation:
Biological agent such as Spider,Water bug, Mirid bug, Damsel fly, Dragon
fly,Grasshopper, Coccinellids, Bracon, wasp, Trichogramma, Telenomus etc should be
conserved
Root dip treatment of rice seedling with Chlorpyriphos is safe for natural enemies.
Augmentation:
Release of Trichogramma japonicum or Trichogramma chilonis
@50,000‐1,00,000 adult /ha 5 times starting from 30 days after transplanting
for control of stem borers and leaf folders
IPM-Yellow stem borer
Clipping the tips
Short stature and shorter
growth duration periods
suffer less damage
Community-wide
destruction of diapausing
larvae (in stubble) through
tillage after harvest,
followed by flooding,
reduces stem borer
populations resulting in low
incidence in the next crop
Insect Pests of Rice
Paddy Stem Borer Dead Heart Symptom Chaffy Grains
Planthopper
 If insect attack during early stage of growth, the
entire plant may dry up.
 Under favorable condition of high humidity,
optimum temperature, high nitrogen application and
no wind, the population increases very rapidly and
 hopper burn is observed localities giving brownish
plot in the field.
 as vectors for transmission of rice tungro virus
disease.
 Nymph and adult caused damage by
sucking cell sap from the leaf which turn
yellow.
BPH GPH
 Close planting creates favorable micro climate for rapid development of hopper population.
 Hence spacing of 20 x 30 cm should be followed.
 Alternate drying and wetting of field during peak infestation and drain standing water from the field checks
hopper population.
 Avoid high dose of nitrogen fertilizer application.
 Mirid bug are predator of egg and nymph of hopper.
 Spray 0.2% Quinalphos 25 EC (8 ml/ liter water) or 0.2% Endosulfan 35 EC (5.7 ml/ liter water)
Management:
Traditional Method
 Pour kerosene on a flooded field and drag a rope across the foliage bending it into kerosene film on
the water.
 The insects dislodge into the oil and get killed.
 And the filed are drained off after 6 (six) hours to prevent phytotoxicity.
Both nymphs and adults suck sap from the plant tissues.
Excess draining of the plant sap results in wilting and
drying of the plants in clusters known as “hopper burn”.
It starts in circular patches and then covers the whole
field.
Early and synchronous planting.
(2) Use of balanced
fertilizer dose and avoid using excessive ‘N’ fertilizer or manure.
(3) Alternate wetting and drying of the rice field.
(4) Use resistant/tolerant rice cultivars e.g. Lalat, Sebati, Konark,
Surendra, Tapaswini, Meher, Vijeta, Durga, Rambha, Kanchan etc.
(5) Strict surveillance of rice fields for pests and defenders (mirid
bugs and spiders).
(6) Setting up of yellow sticky traps to
attract and kill hoppers.
(7) Foliar spraying of NSKE @5%
or neem oil 0.5% or neem based commercial pesticides
300ppm @ 2.5lit/ha (
foliar spray (thiamethoxam – 100g/ha, imidacloprid –125ml/ha,
ethiprole 10EC – 500ml/ha, or imidacloprid 0.2G – 25kg/ha in the
main field.
Brown planthopper
• High dosages of nitrogenous fertilizers, close spacing, and high
relative humidity increases planthopper populations.
• Sensible use of fertilizer by splitting nitrogen applications can also
reduce chances of plant hopper outbreaks.
• Draining rice fields can be effective in reducing initial infestation
levels. The field should be drained for 3 - 4 days when heavy
infestations occur.
• Growing no more than two crops per year and using early-maturing
varieties reduces planthopper abundance and damage.
• Synchronous planting (planting neighboring fields within 3 weeks)
and maintaining a rice-free period may be effective.
IPM-Brown plant hopper
• High dosages of nitrogenous fertilizers, close spacing, and high relative humidity
increases planthopper populations.
• Sensible use of fertilizer by splitting nitrogen applications can also reduce
chances of plant hopper outbreaks.
• Draining rice fields can be effective in reducing initial infestation levels.
Brown Plant Hopper Hopper burn Symptom
Green leafhoppers
Green leafhoppers have gained economic
significance because of their ability to serve as
vectors for transmission of rice tungro virus
disease.
Two species, Nephotettix virescens and
N.nigropictus are predominant.
Both nymphs and adults suck the sap from the
leaves and tillers with their sucking
mouth parts resulting yellowing of the leaves which
later become brown and dry up from
the tip downwards.
use resistant/tolerant varieties like Heera, Pathara,
Badami, IR-36, Navin, Lalat, Rambha, Kanchan,
Parijat, Srabani, Moti,Tulasi etc.
Green leafhoppers
• Reducing the number of rice crops to two per year and synchronized
• Transplanting older seedlings (>3 weeks) also reduces viral disease susceptibility transmitted by
leafhoppers.
• y Avoid planting at peak activity (shown by historical records) period to avoid infestation.
• y Early planting within a given planting period, particularly in the dry season, reduces the risk of insect-
vector disease.
• Nitrogen should be applied at an optimal level to discourage population buildup and influence plant
recovery.
• Good weed control in the field and on the bunds removes the preferred grassy hosts and promotes crop
vigor.
• Crop rotation with a non-rice crop during the dry season decreases disease reservoirs.
• Upland rice intercropped with soybean reduces the incidence of leafhoppers on rice compared to rice
alone
(1) Avoidance of mono-cropping. (2) Use of balanced
fertilizer dose and avoid using excessive ‘N’ fertilizer or manure.
(3) Strict surveillance of rice fields for pests and defenders.
(4) Mechanical killing of larvae of leaf folders (LF)
by collecting and destroying affected leaves.
(5) Setting up of light traps to attract and kill
adults.
(6) Release of egg parasotoid Trichogramma chilonis @ 1 lakh / ha
starting from
15 Days after planting(DAP) for 5-6 times at 7-10 days intervals.
(7) Bacillus thuringiensis (Bt) based commercial bio-pesticides may be
sprayed @1kg or 1lit/ha
at 7-10 days intervals in the
evening hours.
(8) Foliar spraying of NSKE @5% or neem oil 0.5% or neem based
commercial bio-pesticides 300ppm @ 2.5lit/ha or 1500 ppm @
1.5lit./ha. (9) (flufenoxuron 10DC/ lambda-cyhalothrin 2.5EC @ 1
lit/ha or fipronil 5 FS –
1 kg/ha or lambda-cyhalothrin 5EC (Karate) –500 ml/ha or
lubendiamide(39.35 SC) – 175ml/ ha or indoxacarb14.5SC –
200ml/ha.
Yellow stem borer
• Clipping the tips of seedlings before transplanting greatly reduces the carryover
of eggs from the seedbed to the transplanted fields
• Rice varieties with short stature and shorter growth duration periods suffer
less damage than long growth duration varieties.
• Rice – rice with shorter growth duration varieties suffer less damage than long
duration varieties. This may be because of stem-borer mortality due to
harvests occurring twice in the double cropping system.
• Community-wide destruction of diapausing larvae (in stubble) through tillage
after harvest, followed by flooding, reduces stem borer populations resulting in
low incidence in the next crop
Rice case worm
Rice Caseworm: Paraponyx stagnalis
(Lepidoptera : Pyralidae)
Damage symptoms:
• The larva feeds on the foliage by scrapping chlorophyll leaving horizontal rows of
green material.
• The leaf tips are sharply cut off and the cut portions are turned into cylindrical
tubes, is either attached to the plant or seen floating on the water surface
Caseworm(Nymphula depunctalis) is commonly
found in rice fields in low populations.
Due to continuous water stagnation in fields, it can
build up and cause severe loss in early stage.
In severely damaged areas the whole crop may have
to be resown/replanted.
Feeding damage includes cutting off the leaf tips to
make leaf cases, patches of severe defoliation, stunted
growth and death of plants.

Caseworm damage
Management
Cultural practices:
Drain water from the field.
Keep kerosene soaked gunny bags in the field water and dislodge the leaf cases by passing
rope or branches of thorny plant.
The use of correct fertilizer application, wider spacing (30 × 20 mm), and early planting.
Biological Control:
Spiders, dragonflies, and birds eat the adults.
There is a nuclear polyhedrosis virus, which is a potential control agent against
the rice caseworm.
• Rice fields with wider hill spacing (30 x 20 cm) usually suffers less
damage from caseworm.
• Early planting may escape the peak caseworm moth activity period.
• Draining of fields for 5-7 days kills caseworm larvae.
• Use of older seedlings reduces the duration of the susceptible stage
of the crop.
• Nitrogen fertilizer use at optimal dosages and split applications
reduce the rice
The larvae live in tubular cases made up of cut
portions of paddy leaves around their bodies
made with a silken thread.
(1) Do not allow standing water in the field.
Drain out
standing water.
(2) Mechanical killing of larvae of case worm
by straining running water from the field.
Chemical Management: chlorpyriphos 50% +
cypermethrin 5% @ 1
lit./ha.
Of the three species of gundhi bug, Leptocorisa
oratorius is common.
Adults and nymphs suck the milk from
developing grains
Infestation is characterised by:
 discolored panicles with brownish spots
 empty or ill-formed grains in the panicles.
Gundhi Bug
Preventive measures
Remove weeds from fields and
surrounding areas
Biological control
Small wasps parasitize the eggs and the
meadow grasshoppers prey on them.
Both the adults and nymphs are preys to
spiders, coccinellid beetles and
dragonflies
Fungus infects both nymphs and adults.
The nymphs and adults are active during early morning
and late afternoon feeding on the milk of the rice during
the milky stage. The area around the puncture hole turns
brown. The puncture hole serves as a point of entry of
several pathogens which cause grain discolouration.
Affected grains in the panicle become chaffy. Attack in
dough stage causes shrivelled grains.
Non chemical Management: (1) Keep fermented snail or
crab bait @ 20-25/ha to attract
and divert pests from sucking milk of rice grain. (2) The
extract of 2.5kg garlic + 500g
tobacco leaves + 500g washing powder sprayed over one
hectare area during milky stage
of rice controls 80% gundhi bug.
Chemical Management: (1) When the pest crosses ETL i.e.
1 bug/ hill then give spray
with DDVP – 500ml/ha/ carbaryl – 2 kg/ha/ abamectin –
500ml/ha/ phosphamidon 40SP
–1 lit/ha or dusting with malathion 5%D @ 25kg/ha.
 Young larvae feed on tender leaf by scrapping green
matter.
 Old larvae feed inside the fold by scrapping green
matter.
 The scrapped leaf becomes membranous, turn white
and than finally wither.
 Heavily infested crop sows streaks on the leaf and
appear whitish from distance.
Rice leaf folder
Cnaphalocrosis medinalis (Lepidoptera: Pyralidae)
 Rice cultivation with HYV’s and applications of high levels of N fertilisers helped leaf
folder (Cnaphalocrocis medinalis Guenee) becoming a major pest.
Field damage
 The larvae fold the leaves longitudinally and feed resulting in linear pale white stripe
damage.
 In cases of severe infestation, the crop gives whitish appearance.
Field damage
Management:
• Remove grass weeds from bounds around paddy field.
• Light trapping of adult help to reduce pest population.
• Release Trichogramma japonicum or T. chilonis @ 50,000 to 1,00,000 adult.
• Spray insecticide at economic threshold level of 10 % damage.
• 0.12 % Fenetrothion 50 EC (2.4 ml/ l water), 0.2 % Carbaryl 50 wp (4 ml/ l water) or 0.1 %
Monocrotophos 36 EC (2.7 ml/l water) or 0.15% Chlorpyriphos 20 Ec (7.5 ml/l water)

Release Trichogramma
japonicum/T.chilonis cards @ eggs
40,000/acre at 30 days after
transplanting
Do not spray insecticides when
abundant spider population/
sufficient beneficial insects are
available
Rice Hispa:
 Hispa (Dicladispa armigera) is a major pest of rice
 The adult beetles feed on the epidermal tissue of the
leaves and the grubs mine the leaf tissue.
 White blotches appear on leaves and in severe epidemics
leaves dry up and the crop presents a scorched
appearance.

1. Clipping the tips of leaves at the time of transplanting
Biological control:
1. Small wasps that attack the eggs and larvae.
2. Reduviid bug eats upon the adults.
3. Fungal pathogens that attack the adults.
Chemical control:
1. Application of Phorate 10 G in nursery minimises infestation.
2. In the main field spray 0.15% Chlorpyriphos 20 EC (7.5 ml/l water) 0.2% quinalphos 25
EC (8 ml/ l water).
Rice thrips
Damaged leaves Damaged field
Paddy thrips: Stenchaetothrips biformis
(Thripidae: Thysanoptera)
Damage symptoms
 Usually occurs in rainfed rice in nursery or seedling stage
 Both nymphs and adults suck sap from leaves leading to leaf tips resembling that
of needles
 In severely infested areas, the plants appear lanky and sickly
Management:
Cultural practice:
Flooding to submerge the infested field for 2 days as a cultural control practice is
very effective against the rice thrips.
Biological control:
Coccinellid beetles, anthocorid bugs, and staphylinid beetles are biological control
agents that feed on both the larvae and adults.
Chemical control:
Application of phorate 10 G @ 75g or carbofuron 3 G @ 1.25kg / seed bed (300 sq
mt area) followed by light irrigation.

Army worm
Armyworm/Climbing
cutworm: Mythimna separata
(Lepidoptera :
Noctuidae)
Damage symptoms:
Early instar larvae skeletonise the
leaves whereas later instar larvae
are voracious feeders on leaves
during night.
Cut worm Panicles are cut off from the base
Fed upon leaf blades
Management:
Preventive measures:
• Remove weeds from fields and surrounding areas
Cultural practices:
 Flooding seed bed is the best defence
 Digging pits or trenches, covered with leaves gives caterpillar a place to take
shelter from the sunlight
 Ash filled trenches around the field serve as barriers
 Placing branches around the field gives a place for armyworm to congregate
where than can be easily collected by hand.
 Gall midge (Orseolia oryzae) - A key pest
 Six biotypes of this pest are reported in the country
 The maggot feeding induces an elongation
of the leaf sheath into a ‘gall’.
 The ‘silver shoot’ or ‘gall’ resembles an onion leaf.
Profuse tillering is seen and resulting tillers do not bear
panicles.
Gall midge Grow Resistat varieties
Gall midge
• Plowing under the ratoon of previous crops can reduce infestation.
• Control of grassy weeds and wild rice (alternate hosts) from
surrounding areas can reduce gall midge incidence.
• Draining of rice fields for 5-7 days affects midge populations.
• Planting of early and using early maturing varieties may help to avoid
high infestations.
• Using only moderate amounts of nitrogen and potassium fertilizers
and adopting split applications to reduce population growth rates.
• Avoiding staggered planting (complete planting in an area within 3
weeks) to reduce infestation.

Rice hispa
 Hispa (Dicladispa armigera) is a major pest of rice in Assam,
Meghalaya, Tripura, Manipur, A.P, M.P and U.P.
 The adult beetles feed on the epidermal tissue of the leaves
and the grubs mine the leaf tissue.
 White blotches appear on leaves and in
severe epidemics leaves dry up and the
crop presents a scorched appearance.
They are sporadic pests mainly causing damage in
coastal and northeastern states.
Larvae are polyphagous - feed on leaves during
vegetative stage and cut the panicles at maturity.
Severe infestation leads to deskeletonisation of
leaves.
Cut worms/Ear cutting caterpillar
Mealy bug
The pest is common on plants growing in
dry cultivated areas and in fields with
uneven soil surfaces.
Adults and nymphs suck sap from the
stem resulting in stunted plant growth and
yellowish curved leaves.
Under heavy infestation the panicles do
not emerge completely. Infestation is
localized in patches and individual plant
hills may even dry off.
 Usually termites occur under rainfed upland conditions with soils rich
in vegetable matter.
 Initially , the affected plants show symptoms of yellowing and wilting
in patches.
 Later, the infested plants lodge due to tunnelling and feeding on the
subterranean parts of stem and roots.
Termites
 White grubs are less common in rice environments.
 However, in recent times this has emerged as a serious
pest in Kumaon region of Uttaranchal under rainfed
conditions.
Emerging Insect Pests
• Common in rainfed and irrigated wetland environments
during the vegetative stages
• Prefers continuously cropped irrigated rice areas and poorly
drained fields
• Damage characterized by reddish brown or yellowing of
leaves, decreased tillering, stunting of plant leading to no
panicle formation or incompletely exerted panicles.

Predators
Egg Parasitoids
Larval Parasitoids
Pupal Parasitoids
Monophagous Predators
Oligophagous Predators
Polyphagous Predators
Generally speaking the most common features of insect predators are:
 Kill and consume more than one prey organism to reach maturity
 Relatively large size compared to prey
 Predaceous as both larvae and adults
 Larvae/nymphs/grubs are active with sensory and locomotory organs
 Frequency of individual prey items in the diet may be influenced by:
 Prey environment
 Prey preferences
 Competition with other predators
 Suitability of prey
Predators’ characteristics
Several species of predatory bugs (Heteroptera) are economically important biological
control agents
Most are polyphagous, feeding on a wide array of arthropod prey
Important heteropteran predators used in augmentative biological control:
• Coccinellidae: Coccinella septempunctata (aphids, etc.,)
• Anthocoridae: Orius spp. (thrips, aphids, etc.,)
• Miridae: Cyrtorhinus lividipennis, Macrolophus pygmaeus, Nesidiocoris tenuis (whiteflies,
leaf miners, spider mites. etc.,)
• Geocoridae: Geocoris spp. (whiteflies, thrips, mites. etc.,)
• Pentatomidae: Podisus, Perillus, Arma spp. (lepidopteran and coleopteran larvae)
• Reduviidae: Rhynocoris spp., Acanthaspis spp. (lepidopteran larvae…)
Predatory insects
PREDATORS
 Timely planting/sowing.
 Pre-sowing irrigation: Many weeds can be controlled by applying pre-sowing
irrigation to area where nursery or seedlings are to be transplanted. The
emerged weeds can be ploughed under.
 Raising of healthy nursery.
 As far as possible rice seedling should be free from weed seedlings at the time of
transplanting.
 Destruction of left over nursery, removal of weeds from field and cleaning of
bunds.
 Normal spacing with 30-36 hills/ m2 depending on the duration of the variety.
 30 cm alley formations at every 2.5 to 3 m distance in plant hopper and sheath
blight endemic areas..

Seed treatment
• Bijamrut +cow urine in combination with appropriate biofertiliser
like Azotobacter and Rhizobium are good seed treating agents
• In case of foot/root rot disease infested soil, Trichoderma viridi
inoculant and Azotobacter inoculants can be used for seed
treatment
• Soak seeds in bijamrut for 10-15 min and treat with Azotobacter @
300gm per 10kg of seeds
• Similarly soak the seeds of legume crop in bijamrut for 10min
followed by Rhizobium treatment
• Dry the seeds in shade and sow
Application of Jiwamrut
• Jiwamrut at the rate of 200lit/acre 3-4 times during crop period
• First dose before sowing, second dose after 20 days of sowing and
third dose after 45 days of sowing
• It can be applied along with irrigation water or by sprinkling over
ane acre during rains
Foliar Spray
• In cereals, millets or vegetable crops, foliar application of 1:20
diluted Cow urine or diluted vermiwash is effective
• Cow urine and vermiwash in 1:1 ratio can also be used as foliar
spray
• This foliar spray can be repeated at an interval of 7-8 days
Practices at a glance
• Incorporate crop residue after Jiwamrut treatment
• Use 1.5-2 ton compost+rockphosphate
• If needed add concentrated manure
• Use N-fixing tree loppings and other crop/ weed biomass as mulch
• Use Jiwamrut as soil application 3-4 times
• Use vermiwash+Gomutra spray 3-4 times
• Always take 3-4 crops with 30% share to legumes

A number of well known types are involved e.g. Fusarium, Verticillium YES. Bacterial wilt (Ralstonia solanacearum) is a common disease on many crops YES. Tomato and pineapple diseases exhibit, but not a common symptom YES. Nematodes frequently attack the roots of a plant and this causes wilting NO. YES. – results of insect feeding and also injection of toxins by sucking insects Leaf spot YES. Many types involved and wide variety of shapes and appearance YES. Common symptom but with distinct characteristics e.g. water-soaking YES. Quite common but less distinct than most fungal leaf spots NO (NO) Leaf markings do occur but generally not distinctive YES. But not true leaf spots, more the effect of feeding. Canker YES. Cells are killed in stems, including trunks of large trees. YES. Canker is applied in a slightly different way to fungal cankers. NO (NO) Some root lesions may be described as cankers, but this is a loose description NO NO Mosaic NO. Not a symptom which suggests fungal attack. NO YES Note that other factors can produced similar symptoms NO NO (YES) But symptoms are superficial and different from virus diseases Yellowing of foliage (leaves) YES. Often indicates symptoms or infection in other parts of plant e.g. roots, cankers on stem YES. A general or non-specific symptom noting general decline of plant YES. Distinctive feature but not always easy to interpret. May occur without obvious decline of plant YES. A general or non- specific symptom noting general decline of plant YES. Distinctive feature but not always easy to interpret. May occur without obvious decline of plant YES General symptom, often indistinctive Witches’ broom (many branches) YES. Not so common, but be careful to consider this possibility NO NO NO YES. Very distinctive feature but sometimes not so clear – depends on host response YES Beware of mite damage. Normal growth is disturbed by feeding Distortion of leaves YES. Some well-known examples are distinctive, but others much less so NO YES. Distinctive feature, though needs training to identify clearly in field (NO) General symptom in most diseases, mostly the affect of decline in whole plant YES. Distinctive feature, but note that may only be present at YES Aphid feeding in particular. Can be distinctive, though training needed to separate from viruses (e.g.) Reduction in size of leaves (NO) More the general effect of reduced growth (NO) More the general effect of reduced growth (YES) Rare symptom more indicative of phytoplasmas; the two groups share other types of induced symptoms NO YES. Distinctive feature, even more so than viruses. The two causes can be difficult to distinguish in the field NO Generally not a feature but see note on witches’ brooms and mites Galls YES. More common on woody plants YES. Stimulate extra growth on all parts of the plants (YES) Conditions such ‘vein enation’ are unusual and on only a few crops. YES. Typical swellings appear on root, as well as general distortion of root systems NO YES Many of the spectacular and distinctive types are associated with mites
