Four Strobilurin, two premix of Strobilurin and Triazole, and one pyrazole-carboxamide foliar fungicides were tested in a modified in vitro culture plug technique against Colletotrichum truncatum (CT), Fusarium virguliforme (FV), Macrophomina phaseolina (MP), Pythium irregulare (PI), Rhizoctonia solani (RS), and Sclerotinia sclerotiorum (SS) and three Strobilurin and two premixes against Septoria glycines (SG). Under aseptic conditions, a single 6-mm culture plug of actively growing individual fungus was placed inverted on one end inside periphery of 9-cm PDA plates and on the opposite end 6-mm sterilized blotter disc with 50-μl fungicide solution was placed. Tests against SG were by spreading 50-μl spore suspension (1×108 spores/ml) on to PDA and placing blotter disc with 50-μl fungicide in the center. During 12-day incubation in 12-h .. View More»
