Incidence of leaf hoppers was initiated in 34th Mw ( leaf) and thereafter continued up to 42ndmw with disappearance in 43rdand 44th MW. It reached its peak during 36th MW ( leaf) which was favored by min. temp. of and max. temp. of oC with morning % and evening % humidity along with mm rainfall. | Influence of weather factors on the incidence of major pests and its predators of cotton
