leaves turn whitish.
As the result 10 % yield loss may occurred.
Small brownish- orange moth with two and
half zig - zag lines on fore-wings.
Can be seen flying in the field.
The adult females lay eggs on the leaf blade
near
mid-rib.
25. DAMAGE SYMPTOMS
The larva folds the leaf by bringing together
the margins of individual or group of leaves.
Larvae scrap the green matter (chlorophyll) from
within the leaf rolls.
Affected leaves develop white
patches & dry-up affecting the crop
growth.
Critical Stage: Panicle initiation
stage leads to serious grain yield
Loss but can appear any time during
the crop period.
26. MANAGEMENT
•Kranti 50 SP @ 250 g / acre
Or
•Baton -4.9% CS@ 250-300 ml / acre

•The life cycle is completed in 22 to 26 days.
•The 1st instar nymphs are white, whereas the later
instar are brown.
•The pest has intercontinental migration.
28. Symptoms and damage :
•Both nymphs and adults suck sap from the
basal portion of the plants.
•The affected plants show yellowing of leaves,
in a circular patch known as “Hopper burn”
•Later the entire crop dies up.
•The affected stems become soft and unfit for straw.
•Economic Threshold level is 5-10 hopper/hill.

cause 10-70 % yield loss
30. MANAGEMENT FOR
BPH & WBPH
Cultural Practices:
•Judicious use of nitrogenous
fertilizer.
Chemical Control:
Prophylactic Control-
Twins @ 60 gm per acre at 60 DAS

Nephotettix virescens
(Cicadellidae : Homoptera)
• A wide spread pest.
•The nymphs and adults are wedge
shaped and green in colour.
•The adults have a black spot on
each forewing.
32. Damage symptoms
The adults & nymphs of GLH
suck cell sap from leaves.
The affected plants turn yellow and remain
stunted with less number of tillers .
E.T.L. is 10-20 hopper/hill
•They act as a vector and transmit
“Rice Tungro” virus disease also
•Yield loss due to 3-65 %
34. * Infection may starts at seedling stage from
Weeds.
* Symptoms are identified as leaf rot.
* Later on base of seedlings is infected and whole
plant is killed.
• Occurring in all states in transplanted rice.
• Peninsular area is more prone to the
attack.
SHEATH BLIGHT (Rhizoctonia solani)
Major Diseases
35. * Visible damage symptoms appears at tillering stage
* The infected leaf sheath
becomes discolored
at or above water level.
* Large elongated, oblong water
soaked lesions are formed and
finally turn brown to dark brown
which looks like snake skin.
Lesions on leaf sheath of rice
Left : lesions in early stage
Right : lesions in later stage
36. * The pathogen later on infects leaf
blade also and infected leaves give
white blotch appearance.
Spreading lesions to
upper parts
Lesions on leaf blades of rice
Sometimes these lesions are mistaken
for leaf blast.
37. Favorable conditions for sheath blight
1. High temp. during night (23º - 25ºC) &
high RH (> 96%)
2. Cultivation of high yielding and early
maturing varieties.
3. Cultivation of early maturing varieties .
4. Heavy application of fertilizers, specially
of nitrogen.
5. Dense planting of crop.
39. Damage caused by Sheath blight
1. Absorption of nutrients and water through
roots is decreased.
2. Diseased rice plants become prone to lodging.
3. Death of whole infected plants occur.
4. During moderate infection 5-10% and during
heavy infection 30-70% yield losses occur.
40. MANAGEMENT
Avoid excess application of Nitrogen.
Apply Remote Power
Captan 70%+Hexaconazole 5% WP
@ 350-400 gm /acre.
Or
Tango Super @ 200 ml per acre
The best time for
1st application at Tillering.
2nd application at booting stage.
3rd application at heading/penicle.
41. BLAST
(Pyricularia oryzae)
• Highly destructive disease of rice.
• Affects all parts of the plant.
• Most conspicuous when attacks leaf
blade and the neck.
• Also attacks other parts like - leaf
sheath, rachis, joints of the culm,
glumes.
Phases of blast depend on crop stage
SEEDLING BLAST
•Highly destructive disease
of rice.
•Early infection in nursery
results in death of affected
Plants.
42. LEAF BLAST
•Spots first appear as minute brown specks,
which later on become spindle/eye shaped.
•Center of the spot is grayish with brownish
margin.
•The several spots later on coalesce and the
whole leaf withers.
•Lower nodes of stem are affected,
which turn black and rot.
•Black & brown spot are seen on the rachis
and glumes.
•The affected culm can be pulled out
(Leading to total yield loss).
NODE BLAST (STEM-INFECTION)
43. NECK BLAST
• The neck tissues are most susceptible to
blast at just ear emerging stage.
• As the result ear heads are broken down.
• The spots are grayish-brown, later turning
to black.
The affected panicle falls, showing typical
neck phase of the disease (Leading to
total yield loss).
The neck symptoms may be mistaken for
stem borer damage or sheath blight.
If attack occurs at grain filling stage,
grains will be partially filled, but the
kernels will be chalky & brittle or may
remain green.
44. FAVOURABLE FACTORS FOR
BLAST INCIDENCE
• Cool Nights (20-24oc)
• High Humidity (>90%)
• Heavy dew formation and foggy weather during early
hours.
• Application of higher doses of nitrogenous fertilizer.
• Upland rice is more susceptible than wetland rice.
• Delayed transplanting / sowing.
• Sandy soil & Cold irrigation water.
45. DISEASE MANAGEMENT
Cultural:
• Early planting
• Judicious use of Nitrogenous
fertilizer.
• Do not allow nursery bed to dry
• No close planting
• Resistant varieties
46. Chemical Control
Apply Sandesh (Isoprothiolene 40% EC)
Dose- 300-400 ml per acre
Time of Application
1. At 60-70 DAT ppr during Panicle
Intiation
2. Repeat at 15 days after I spray or
when disease is visible
47. CHEMICAL CONTROL
Veer-75 WP @ 120-160 g / acre.
•Time of application
•Apply at initial notice of symptoms.
•Just before panicle initiation stage and repeat
after 15 days.
48. Bacterial Leaf Blight (BLB)
(Xanthomonas campestris pv. oryzae)
LEAF BLIGHT STAGE:
•On leaf blades, lesions begin at one or both the
margins and also from tip as yellow to white
water soaked stripes.
•The mature lesions appear straw coloured
with wavy margins.
•Later on the entire leaf may die.
On the surface of young lesions, milky
or opaque dew drops may be observed
in the early morning.
Symptoms
49. • Kresek (wilt) stage:
•Less common but most destructive at seedling stage.
•Appears 1-6 weeks after transplanting.
•Initially plants wilt & finally die.
50. MANAGEMENT :
Drain out the water when 1st symptom occurs
and dry field till cracks developed.
• Stop use of Nitrogenous fertilizers.
• Use of resistant varieties.
Note: Chemical control is not very effective
against BLB.
52. BACTERIAL LEAF STREAK
(Xanthomonas campestris pv. oryzicola)
• Water-soaked to
translucent inter-
venal streaks.
• Run parallel to the
veins.
• The streaks later-on
turn yellow to
orange brown.
53. * Bacterial exudation is observed as yellow
amber coloured drop-lets.
* Bacterium enters the plant through mechanical
injuries or natural cell openings (stomata).
CONTROL : Same as BLB mgt.
54. FALSE SMUT
Ustilaginoidea virens
* More severe in years of high rainfall.
* Symptoms visible only after panicle
emergence.
• At milky stage, grains are
transformed to velvety greenish balls.
* Hybrid paddy varieties and low land
area are more prone.
Favorable conditions for False Smut:
Minimum temp. (20ºC) with RH >92% &
cloudy weather before & during flowering.
55. MANAGEMENT :
Tango Super @200
gm or
Srizol
Application time:
1st at just before the
panicle emergence and
2nd after 15 days
56. BROWN LEAF SPOT
(Helminthosporium oryzae)
•The mature oval spots on
leaves are brown
with gray on white centres.
•Black or dark brown spots
appear on glumes.
• Blackish spots are also found
on grain.
• Economic loss as yield
quality is deteriorated.
57. MANAGEMENT :
• Avoid infected Seeds
• Seed Treatment with
Acer
• Foliar spray with
Acer @ 250-300 g / acre
+
Veer @ 120 gm per acre
