Abstract
Phosphorus solubilizing bacteria (PSB) and Potassium solubilizing bacteria (KSB) plays a vital role in converting these nutrients into forms that plants can readily absorb, thus enhancing soil fertility and crop yields. The compatibility of phosphorus and potassium solubilizing bacteria with 8 fungicides was tested under laboratory condition. The eight fungicides tested against PSB-1, the Carbendazim 50% WP, Propiconazole 25% EC and Carbendazim 12% + Mancozeb 63% WP were found highly compatible with phosphorus solubilizing bacteria and rest of the five fungicides viz., Mancozeb 75% WP, Zineb 75% WP, Metalaxyl 35 % WS, Azoxystrobin 18.2 % + Difenoconazole 11.4 % SC, Azoxystrobin 11% + Tebuconazole 18.3 % were incompatible with the test bacterium. The treatment T8 (Azoxystrobin 11% + Tebuconazole 18.3 %) were found statistically at par at 48 and 72 hrs of incubation at 50% of recommended dose and recommended dosages. the eight fungicides tested against KSB-2 Carbendazim 50% WP, Propiconazole 25% EC and Carbendazim 12% + Mancozeb 63% WP were found highly compatible with phosphorus solubilizing bacteria and rest of the five fungicides viz., Mancozeb 75% WP, Zineb 75% WP, Metalaxyl 35 % WS, Azoxystrobin 18.2 % + Difenoconazole 11.4 % SC, Azoxystrobin 11% + Tebuconazole 18.3 % were incompatible bacterium with the test bacterium. The treatment T8 (Azoxystrobin 11% + Tebuconazole 18.3% SC) and treatment T1 (Mancozeb 75% WP) were found statistically at par at 48 and 72 hrs of incubation at 50% of recommended dose and recommended dosages.
