North western Indian cotton belt is sole irrigated tract in pan India but it is under threat of pink boll worm which devastated the cotton during 2021.
Now new season would be starting in 60-90 days from today. The productivity in this part of India has been badly affected.
Though area to be cultivated is more than 10 lakh ha comprising states of Punjab, Haryana and Rajasathan but still apprehensions of damage are not being ruled out due to callous attitude of growers to remove stalks stacking around fields.
Lesson learnt by me is to remove entire cotton debris and stalks prior to next season cropping starts as this pest is monophagous and survives primary on cotton crop.
What are your opinions and guide lines to minimize the incidence of Pink boll worm.

The suggested calendar irrigation termination, defoliation and crop ploughing can achieve the maximum impact for reducing PBW populations..Use of pheromones, transgenic cotton, augmentative biological control and in-season insecticidal control can be can determined the PBW infestation levels and economic viability.
To analyze the technical and economic feasibility of using crop rotation in the area, using insecticides with good efficiency but showing selectivity to the possible natural enemies of this pest. Perform on-site sampling, with control at the beginning of infestations. Destruction of crop residues after harvest and of weeds of the botanical family Malvaceae.@Madhukar Baburao Deshmukh
