Comparative Effect of Organic and Synthetic Fertilizers on the Infestation of Sucking and Bollworms Insect Pest Complex on Different Varieties of Cotton (Gossypium hirsutum L.)
Ejaz Parvez, Shahid Hussain , Abdul Rashid and Shahid Nisar

Abstract:
To evaluate the comparative effect of organic and synthetic fertilizers on the infestation of sucking insect pests viz, Whitefly (Bemisia tabaci) Jassid (Amrasca davastans) Thrips (Thrips tabaci) and percent damage by spotted bollworms (Earias spp.) and American bollworms (Helicoverpa armigera) on six cotton varieties viz, NIAB-98, FH-900, CIM-552, FH-901, NIAB-86 and NIAB-Krishma, it was revealed that there was no significant difference of mean seasonal per leaf population of sucking insect pests and bollworms on each cotton variety when compared between organic and synthetic fertilizer treatments. However the crop grown in organic fertilizer harbour lesser number of insect pests. Use of organic fertilizer can be integrated with rational/judicious use of pesticides and use of synthetic fertilizers/pesticides may be minimized.
