【摘要】 为探究新型杀菌剂HNPC-A3107的杀菌作用机制,选择黄瓜灰霉病原菌为对象,研究了HNPCA3107对灰霉病菌的抑制作用以及对灰霉病菌丝体内含物渗漏的影响。试验结果表明HNPC-A3107对黄瓜灰霉病原菌具有较强抑制作用,其EC₅₀=1.75 mg·L^-1; HNPC-A3107对黄瓜灰霉病原菌丝体内含物渗漏有显著影响。破坏细胞膜通透性可能是HNPC-A3107发挥杀菌作用的机制之一。更多还原

【Abstract】 In order to explore the fungicidal mechanism of action of a new fungicide HNPC-A3107, the inhibitory effect of HNPC-A3107 on Botrytis cinerea and the effect on the leakage of substances in mycelia of Botrytis cinerea were studied. The results showed that HNPC-A3107 had a strong inhibitory effect on Botrytis cinerea with an EC₅₀ of 1.75 mg·L^-1; HNPC-A3107 had a significant effect on the leakage of the mycelium of Botrytis cinerea.The destruction of membrane permeability may be one of the fungicidal mechanism of action of this new fungicide HNPC-A3107.更多还原
