Abstract:
Taking Coniella castaneicola as material,growth performance of the fungus under different media,temperatures,pH value,light periods,carbon and nitrogen sources were tested,and toxicity of seven fungicides to C.castaneicola was determined.The results showed that the optimal medium,temperature,pH value,carbon source and nitrogen source for the mycelial growth of the fungus was AEA,28℃,5.0,Mannitol and NH4NO3,respectively.However,light duration had no evident impact on the mycelial growth.The results also showed that Epoxiconazol had the highest toxicity,and the propineb was the lowest and the EC50 value was 0.071 9,0.087 6,0.185 7,0.445 0,0.656 9,0.741 2,78.638 4 μg/mL,respectively.The results had laid good foundation for further studying the occurrence and control of grape white rot.
