Abstract

Cotton is one of the most important economic crop in India. About 124.4 Mha was cultivated in 2018–2019, with total production of 370 lakhs bales. The pink bollworm is one of the most vicious pests of the cotton crop. Physical, chemical and biological techniques can be used to control it. This bollworm cotton worst enemy, by which yield and quality of cotton fiber will be affect. The chemical application does not kill the bollworm pest due to hidden in cotton bolls. Hence the chemical treatment does not control the bollworm effectively. Challenging task to control the pink bollworm in cotton field, i.e., sustainable mechanical solution was considered for the study. Cotton stalk shredder cum uprooter will shred the cotton stalk/ boll into tiny pieces by which oviposition site of bollworm destroyed and uprooter will uproot the cotton stubbles which are erected. 80 % of green boll are destroyed by the cotton stalk shredder and 76 % of larvae were killed. Cotton stalk shredder is very effective in decreasing the larval population present in the field after harvesting. It’s found has best sustainable solution for controlling pink boll worm.

Keywords

Cotton stalk shredder, pink bollworm, and uprooter

Conclusion

Cotton stalk shredder cum uprooter is used by the farmer for shredding and uprooting the cotton stalk and stubble left after in the field. Pink bollworm is major threat pest in left in the field after harvesting operation. This egg and larvae present in the unopened green boll will grown and causes effect to next season cotton crop. Cotton stalk shredder cum uprooter will shred the green boll and stalk in small pieces. 80 % of green boll are destroyed by the cotton stalk shredder and 76 % of larvae were killed. Cotton stalk shredder is very effective in decreasing the larval population present in the field after harvesting. It’s found has best sustainable solution for controlling pink boll worm.
