Cultural control methods are regular farming practices used to destroy pests and prevent injury. The main methods discussed are tillage operations, crop rotation, trap cropping, field sanitation, timing of sowing/planting, and use of resistant varieties. Tillage exposes pests to predators on the soil surface. Crop rotation and trap cropping disrupt pest life cycles. Field sanitation removes hosts for pests. Adjusting sowing times can prevent pest infestations. Resistant varieties have traits that make them less vulnerable to certain pests. While cultural controls are environmentally friendly and work with other methods, they require knowledge of pest ecology and long-term planning as full control is not guaranteed.

cultural control..

2. A) Cultural Control🌾
Definition:
Regular farm operation So
performed as to destroy Insect or Pest &
prevent them from causing in.jury.

3. Methods.
• 1) Tillage operation
• 2)Crop Rotation
• 3) Trap Cropping
• 4) Sanitation of field
• 5) Time of sowing / planting
• 6) Use of resistance variety
• Merits& Demerits.

4. 1) Tillage operation⛏️
• Ploughing & other tillage operation expose to (insect) to upper soil
surface which are picked by ( bird’s) Or destroy by ( Heat).
• E.X:- Bihar hairy caterpillar, Fruit fly,Gram pod borer
• It also help in removal of weeds which may serve as host for insects.
Tillage is the agricultural prepration of soil
mechanical agitation of various types.

5. 2) Crop Rotation:-
Growing different crop every year.
Crop rotation- Cereal crop- Insect.
Legumes
Repeat- legume-Insect dominant.

6. 3) Trap cropping.
• The pest which effect the
main crop they will be
diverted towards the the
trap crop main crop will be
safe.
• E.g Okra Is good trap
crop Fir cotton to attract
Jassids & spotted
bollworming.

7. 4) Sanitation of field.
Removel & destruction of all undesirable
plants plant debris weeds & clean cultivation
of field.insects use the plant residues weeds
as host& increase the pest attack in next
season. e.g. Sugarcane borer.

8. 5) Time of sowing /planting.
• Adjusting time of sowing infection of
some pests can be prevented .if the planting
& egg laying time are same then pest attack’
the crop.
• E.g Sugarcane should be harvested before mid Feb to avoid egg
laying of top borer.

9. 6) Use of resistant varities.
• Some morphological or genitic factors
associated with the variety make the variety
resistant for some pest
• E.g. Deshi cotton is more resistant to jasids
whitefly& bollowarm than American cotton.

10. Merits Demerits.
• May be Cheap & simple.
• Environmentaly Safe
• It is well matched with other
methods of pest control.
• It gives least chance of insect
development.
• Knowledge of ecology &
biology is essential.
• Timing decides Success
• No complete control.
• Required long term planning.
