F240 of β2-Tubulin Explains why Fusarium graminearum is Less Sensitive to Carbendazim than Botrytis cinerea.

abstract：:Preplant soil fumigation with metam sodium is used worldwide to control soilborne diseases. The development of accelerated degradation of pesticides in soil, including metam sodium, results in reduced pesticide efficacy. Therefore, we studied microbial involvement in accelerated degradation of methyl isothiocyanate (M...
