Abstract

The experiment was made to investigate the yellow vein mosaic disease epidemiology in okra crop under natural condition. In multiple linear regression equation, population of whiteflies decreases by increase of maximum temperature. Coefficient of multiple determinations R2 value (0.970) represents that 97% influence in the population of whiteflies by five independent variables like temperature (min and max), relative humidity (min and max) and rainfall. Under study of VRO-6, Pusa Sawni and Sonachi, positive relationship of vector and incidence were found in all three cultivars. However in linear equation, maximum R2 (0.701) was stand for Pusa Sawni. Among all treatments, a module consisting seed treatment with Imidacloprid and sowing of two rows of maize border with spraying of imidacloprid +Neem oil spray until fruit formation showed least incidence (15.47%) of disease. The study focused on ecology that creates pressure on whitefly population on crop which possibly will help for understanding epidemiology and formulating management strategies. Furthermore, incorporated function of insecticides will make possible to develop management module.
