ABSTRACT

Compatibility of Beauveria bassiana was studied in the laboratory condition with twelve commonly used insecticides for cotton pest management by poisoned food technique. The results were expressed as percentage of growth inhibition of B. bassiana colony on insecticide treated medium. Among the insecticides tested for their compatibility, only chlorpyriphos 20 EC was rated as relatively less toxic to B. bassiana, while, spinosad (45% SC), econeem (1%), quinalphos (25 EC), acetamprid (20%), endosulfan (35 EC) and thiodicarb (75 WP) were slightly toxic. Imidacloprid (17.80% SL) and triazophos (40 EC) were moderately toxic and profenofos (50 EC), indoxacarb (14.5 % EC) and methyldemeton were highly toxic. Results of the present study suggested that except profenophos, indoxacarb and methyldemeton, the rest of the insecticides tested can be safely used along with the entomopathogenic fungi B. bassiana.
