4. An Integrated weed management may be defined as ‘The combination of two or more weed-
control methods at low input levels to reduce weed competition in a given cropping system
below the economical threshold level.’ It has proved to be a valuable concept in a few cases,
though much is still to be done to extend it to the small farmers' level.
Integrated Weed Management (IWM) approach aims at minimizing the residue problem in
plant, soil, air and water. An IWM involves the utilization of a combination of mechanical,
chemical and cultural practices of weed management in a planned sequence, so designed as
not to affect the ecosystem. The nature and intensity of the species to be controlled, the
sequence of crops that are raised in the rotation, the standard of crop husbandry, and the
ready and timely availability of any method and the economics of different weed-management
techniques are some of the potent considerations that determine the success for the
exploitation of the IWM approach.

7. ▶️WEED PROBLEMS-
The total annual loss of agricultural produce varies
due various parts in India is as below-
1) Weeds: 45% 2) Insects: 30%
3) Diseases: 20% 4) Other pests (Rats, wild animals)
A recent estimate shows that weeds cause annual loss of Rs. 1980 crores to Indian
Agricultural which is more than combined losses caused by insects, pests and
disease.Weeds depleted crops environment of nutrients, water, light and space. Crop
yields are reduced considerably.
In addition, weeds interfere and cause inconvenience to agriculture operations. The
quality of produce is reduced by weed infestation.Weed management is an important
component of plant protection improving the production potential of crops.

8. 1. Weeds is a plant growing where it is
not
desired.
Weed is an unwanted plant.
A plant which is out of place.
A plant that is extremely noxious,
useless,unwanted or poisonous.
🔶DEFINITION OF WEED:-

9. 🔷Why Integrated Weed Management ?
One method of weed control may be effective and economical in a situation and
it may not be so in other situation.
No single herbicide is effective in controlling wide range of weed flora.
Continuous use of same herbicide creates resistance in escaped weed flora or
causes shift in the flora.
Continuous use of only one practice may result in some undesirable effects. Eg.
Rice -wheat cropping system - Phalaris minor.
Only one method of weed control may lead to increase in population of
particular weed.

10. 💠Advantages-
It shifts the crop-weed competition in favour of crop.
Prevents weed shift towards perennial nature
Prevents resistance in weeds to herbicides.
No danger of herbicide residue in soil or plant.
No environmental pollution.
Gives higher net return.
Suitable for high cropping intensity.

11. ▶️COMPONENTS Of IWM
Cultural Methods
Mech./ Physical Methods
Chemical Methods
Biological Methods

12. ▶️CULTURAL WEED CONTROL-
Several cultural practices like tillage, planting, fertiliser application,
irrigation etc., are employed for creating favourable condition for the crop. These
practices if used properly, help in controlling weeds.
1.Field preparation-The field has to be kept weed free. Flowering of weeds should
not be allowed. This helps in prevention of build up of weed seedpopulation.
2. Summer tillage:The practice of summer tillage or off-season tillage is one of
the effective cultural methods to check the growth of perennial weedpopulation
in crop cultivation.
3. Maintenance of optimum plant population: Lack of adequate plant population
is prone to heavy weed infestation, which becomes, difficult to control later
Frequent irrigation or rain during initial stage of crop growth.
4. Irrigation and Drainage:induced several flushes of weed. In lowland rice,
where standing water is present most of the time, germination of weeds is less.

13. ▶️5. Crop rotation- The possibility of a certain weed species or group of
species occurring is greater if the same crop is grown year after year.
▶️6. Growing of intercrops: Inter cropping suppresses weeds better than sole
cropping and thus provides an opportunity to utilize crops themselves as tools of
weed management.
▶️7. Mulching: Mulch is a protective covering of material maintained on soil
surface. Mulching has smothering effect on weed control by excluding light
from the photosynthetic portions of a plant and thus inhibiting thetop growth.
▶️8. Intercultivation: It is a very effective and cheap method of weed control
in line sown crop. Most of the intercultivation implements have a blade which
cuts the weeds just below the soil surface and thus kill weeds.

14. ▶️ Mechanical Weed Control -
Mechanical or physical methods of weed control are being
employed ever since man began to grow crops. The mechanical methods
include
tillage, hoeing, and weeding, digging cheeling, sickling, mowing,
burning, flooding,
mulching.mulching, etc.
1. Tillage- Tillage removes weeds from the soil resulting in their death.
It may
weaken plants through injury of root and stem pruning, reducing their
competitiveness or regenerative capacity.
2. Hoeing - Hoe has been the most appropriate and widely used
weeding tool for
centuries. It is however, still a very useful implement to obtain results
effectively
and cheaply.

15. MECHANICAL METHOD BY SICKLE
(HANDWEEDING)

16. ▶️CHEMICAL CONTROL-
Chemicals that are used to kill plants or weeds are called Herbicides.
Their use has been increasing rapidly since 1944 when shaked
[propaquizafops 2.5%+imazethapyr 3.75% w/w ME]
first use as herbicide.
In many instance, they offer most practical, effective and economic
means for controlling weeds.
Pre emergence treatment with herbicides provide early season weed
control. In addition they reduce drudgery of hand weeding.

17. .
Most Used/Popular Herbicides Nowdays-
Selective herbicide :-
shaked, Metalochlor, Butachlor, Isoproturon, Metribuzin, etc.
Non selective herbicide :-
Glyphosate, Paraquat, Imazethapyr, etc.
pre plant herbicide– Fluchloralin, etc.
Pre emergence :-
Simazine, Atrazine, Alachlor, Pendimethalin.etc.
post emergence :-
SHAKED, Sulfosulfuron, etc

18. ▶️Advantages of Chemical Control -
Herbicides can be applied for weed control in crop rows and
where cultivation is impossible.
Herbicides can control many perennial weed which cannot be
controlled by other methods.
Cultivation & manual methods of weed control may injure the
root system.
Pre-emergence herbicides provide early season weed control.
Herbicides reduce the need for pre-planting tillage. They are
extremely useful in minimalzero tillage.

20. ADDING WATER IN THE
SPRAYER:-

21. HERBICIDE SPRAYING:-

22. ▶️Biological Controls:-
Bioagent like insects, pathogen etc., and other animals are used to contro
weeds.
Insect and pathogens infest weeds and they either reduce growth or kill
weeds.
Biological control method can reduce weeds but it is not possible to
eradicate
weeds.
Bioagent Weed
Zygogramma bicolorata Parthenium hysterophorus
Dactilopius selenium Prickly pear
Uroplata girardi &
Octotoma scabripennis
Lantana camera
Cytrobagous Salviniae salvinia molesta

INSECTS

24. Questions asked by Farmers –
Q.1.Is SHAKED harmful to the soyabean crop?
Ans. NO. SHAKED is selective herbicide it doesn’t harm soyabean crop.
Q.2 How Mexican beetles kill the parthenium?
Ans. Grubs after hatching, starts to feed on soft growing leaves which on
maturity prefer mature leaves. Adults also feeds on leaves.
Q.3.What are the types of Herbicides?
Ans. Herbicides are differentciated on the basis of mode of action, Selectivity,
Time of spraying, etc.
Q.4.Is biological control available of all weeds ?
Ans. Not for all weeds but for some major weeds like lantana camera, Prickley
pear have biological controls.
