Abstract:
In Integrated Pest Management, entomopathogenic fungi are a promising biocontrol agent for managing insect populations. Understanding the detrimental impacts of agrochemicals and testing their compatibility are crucial to effective integrated pest management. The present in vitro study was carried out at the Department of Plant Pathology, College of Agriculture, Parbhani. Seven systemic (500, 1000 and 1500 ppm) and non-systemic fungicides (1500, 2000 and 2500 ppm) were evaluated by Poisoned Food Technique. The compatibility was inversely proportional with the concentrations of these fungicides. Among the systemic fungicides only Pyraclostrobin was found compatible at 500 and 1000 ppm and incompatible at 1500 ppm (38.50, 21.66 and 13.83 mm, respectively). Whereas Metalaxyl (08.00, 06.83 and 05.16 mm) and Thiophanate methyl (09.16, 07.66 and 07.00 mm) was incompatible at all concentrations followed by Triazole group and Carbendazim. All the non-systemic fungicides tested were found moderately compatible at 1500 ppm and sulphur and Chlorothalonil were slightly compatible at 2000 and 2500 ppm. At higher concentrations except Sulphur and Chlorothalonil other fungicides were incompatible.
