Pest scouting should be done twice a week during the month of June, July and August due to the threat of whitefly infestation on the cotton crop. Timely eradication of weeds and other host plants is essential to achieve higher cotton production, as they are attacked by whiteflies all the year round. Whitefly serves as the vector of Cotton Leaf Curl Virus (CLCuV) which has been a major threat to the cotton in Pakistan.
Host plants of whitefly include okra, tobacco, potato, eggplant, pumpkin and cucumber. Cotton viruses and pests are mostly present along the banks of fields, water channels and roads. Therefore, management of these weeds in these areas is essential. Cotton weeds include field binweed, burmuda grass, horse purslane, green amaranth, common purslane, false amaranth and purple nutsedge.
