Agriculture Department has advised farmers to allow sheep and goats to feed on unpicked bolls and burs left in the cotton fields after last picking as this will assist in the control of pink bollworm. Pink bollworm is one of the most destructive pests of cotton. The damage is caused by the caterpillars only. They are pink and are found inside flower buds, panicles and the bolls of cotton. They said after last picking, the unpicked bolls should be removed and stem should be cut deep from the base at 6 inches. So that in early spring no any growth occurs from the base of crops and ploughing would be done smoothly in order to remove the pupa stage of pink bollworm living in the soil.
They further added that before the arrival of spring, the barren cotton fields should be ploughed. Deep ploughing should be done in order to remove the weeds and base growth. Remaining stems should be removed and if the stems are used for fuel purpose then those should be tie in bundle and kept in sun for drying. Base of the stem should face direct sunlight so that the remaining bollworm will be destroyed, to avoid emergence of moths during cotton season.
