An experiment was conducted to know the compatibility of Azoxystrobin 25 SC with biocontrol agents by poisoned food technique and turbidity method and with insecticides by emulsion stability test. The biological compatibility was done under glass house condition to find the percent injury. The compatibility showed that Pseudomonas fluorescens and B. subtilis were compatible with Azoxystrobin 25 SC at 5, 10, 50, 100 and 250 ppm, concentration. The physical compatibility studies showed that Azoxystrobin 25 SC was highly compatible commonly used with insecticides viz., Profenphos, Dichlorvos, Monocrotophos, Carbaryl, Dimethoate, Triazophos and Quinalphos. The results from the biological compatibility revealed that insecticides, Dichlorovos and Profenphos were found to be less compatible with Azoxystrobin 25 SC when compared to other insecticides.
