DO'S & DON'TS OF CROPS COTTON
Do's & Don’ts in Cotton Production
- Cotton cultivation should be done only in well drained black cotton soils or red
sandy loamy soils. Take up deep summer ploughing upto 8 inches depth.
- Growing fodder Jowar or maize as barrier crops around cotton and castor and marigold
as trap crop in between cotton rows.
- Use quality certified seed, optimum seed rate and timeliness in sowing.
- Grow tolerant varieties/hybrids which are resistant to insect pests and diseases.
- Seed dressing with Imidacloprid 5 g/kg seed or thiomethoxam 4 g/kg seed.
- Growing intercrop for increasing the effectiveness of natural enemies.
- Use high volume sprayers while spraying weedicides.
- Stem application with monocrotophos or imidacloprid at 1:4 or 1:20 dilution at 20,
40 and 60 DAS for controlling aphids and leafhoppers in initial stages of crop growth.
- Monitoring pests by using sticky, pheromone and light traps. The adult monitoring
should be supported by egg and larval monitoring.
- Bird perches @ 10 to 20 per acre for encouraging bird predation on bollworm larvae.
- Release of Trichogramma egg parasite @ 1,50,000/ha and chrysopa egg larval predator
@ 10000/ha, as soon as the first brood of bollworms are noticed.
- Use of biopesticides Helio NPV @ 500 LE/ha or Bt formulation @1/ha or neem seed
kernel extract (5%) in synchrony with incidence of young larva of Helicoverpa. Neem
oil formulation sprayed to manage whitefly initially.
- Hand collection and destruction of egg masses and skeletonised leaves in respect
- Removal of top leaves by topping of cotton plants when maximum egg laying of Helicoverpa
armigera is noticed (October-November months period).
- Need based application of insecticides.
- Use of poison bait for Spodoptera @ 10 kg rice bran +1 kg jaggery + 1 liter chlorpyriphos
or 250g thiodicarb per acre.
- Removal of cotton stubbles after last picking without prolonging the crop growth
to break the cycles of pests.
- Use well calibrated sprayers.
- Avoid moisture stress during flowering and boll formation stages.
- Take up soil and moisture conservation measures for rainfed crop.
- Foliar spray of 2% urea at the initial reproduction stage is beneficial for increasing
yields in rainfed drought conditions.
- Don’t take up cotton cultivation in saline soils as they are not suitable
for cotton cultivation.
- Don’t cultivate cotton crop in soils with poor drainage.
- sow cotton crop after 15th August in any case. Avoid late sowing.
- Don’t take up intercropping of cotton with similar long duration crops or
those which compete for nutrients or those which hamper spraying operations.
- Don’t apply excess dosage of fertilizers than recommended as it will damage
- Don’t mix bioagents like trichoderm viridi or Rhizobium with chemical pesticides.
- Avoid cocktail mixtures of chemical pesticides.
- Don’t encourage but discourage synthetic pyrethroids.
- Don’t apply sub lethal doses. It will result in pest resurgence.
- Don’t grow susceptible varieties in frequently infected fields.
- Don’t use uncalibrated sprayers as it will result in excess or lower dosage
- Don’t take up plant protection sprayings when ETL of helicoverpa is less than
one larva per plant as it is not economical.
