Abstract

The effect of different concentrations of Dithan A-40 fungicide on the metabolic activities of the wilt fungus Fusarium oxysporum f. fabae and the root rot agent Rhizoctonia solani was studied. All toxicant concentrations reduced energy generation, total phosphorus and nitrogen content of both fungi. In addition, the toxicant caused a shift in free amino acids pool. As a result of these changes, the mycelium dry weight of both fungi was greatly reduced. R. solani was more sensitive to the toxic effect of Dithan A-40 than F. oxysporum.

摘要

研究了不同浓度的代森锌A - 40杀菌剂对枯萎病菌尖孢镰刀菌蚕豆专化型（Fusarium oxysporum f. fabae）和根腐病菌立枯丝核菌（Rhizoctonia solani）代谢活性的影响。所有毒剂浓度均降低了两种真菌的能量产生、总磷和总氮含量。此外，该毒剂还导致游离氨基酸库发生变化。由于这些变化，两种真菌的菌丝体干重均大幅降低。立枯丝核菌比尖孢镰刀菌对代森锌A - 40的毒害作用更敏感。
