Abstract: An in-vitro compatibility studies were conducted with Penicillium pinophilum and some commonly used, commercially available chemical pesticides and fertilizers in sugarcane. The experiment was laid out in a Completely Randomized Design (CRD) with three replications and thirteen treatments. In this study, three treatments of fungicides [Carbendazim 50% WP (Bavistin), Mancozeb 63% WP + Carbendazim 12% WP (SAAF), Thiophenate methyl 70% WP (Roko)], three treatments of insecticides [Thiamethoxam 30% FS (Slayer pro), Chlorpyriphos 50% + Cypermethrin 5% EC (Hamla), Azoxystrobin 2.5% + Thiophenate methyl 11.25% + Thiomethoxam 25% FS (Electron)], three treatments of herbicides [Atrazine 50% WP (Atrataf), Ametryne 80% WDG (Tamar), 2, 4-D sodium salt 44% + Metribuzin 35% + Pyrazosulfuron-ethyl 1.0% WG (Triskele)], three treatments of fertilizers (Urea, Di-ammonium phosphate, Muriate of potash) and P. pinophilum culture grown on PDA served as a control. Among fungicides, Carbendazim and Thiophenate methyl were found to be compatible, whereas Mancozeb + Carbendazim was found to be toxic. The insecticides Thiomethoxam and Azoxystrobin + Thiophenate methyl + Thiomethoxam were compatible, while Chlorpyriphos + Cypermethrin proved incompatible. The herbicides, Ametryne and 2, 4-D sodium salt + Metribuzin + Pyrazosulfuron were incompatible and Atrazine was found to be slightly toxic. Among fertilizers, Urea and Di-ammonium phosphate were found to be compatible and Muriate of potash showed additional colony growth over control.
