Integrated Control of Sucking Pests of Cotton

摘要

COTTON is an important cash crop of Punjab. Punjab state produced a record production of 24.06 lakh bales of cotton lint from an area of 7.32 lakh ha during 1989. In the subsequent years the yield level, however, went down. It was only 17.79 lakh bales from an area of 6.06 lakh ha with an average yield of 499 kg lint/ha or 14.25 q seed cotton/ha during 1994. The national average of seed cotton was only 8.61 q/ha during 1995. The insect infestation is one of the important factor causing reduction in yield. The other factors i.e. varieties, agronomic practices, cropping pattern, adequacy and efficiency of control measures and weather also affect yield of seed cotton.
