本研究采用菌丝生长速率法测定了4种高效低毒杀菌剂对花椒炭疽病的抑菌活性,旨在为花椒炭疽病的有效防治提供理论依据。结果表明:4种供试杀菌剂对花椒炭疽病菌的菌丝生长均有一定抑制作用,但具明显差异。其中,苯醚甲环唑和百菌清的抑菌效果较强,其EC50值分别为2.18mg/L和2.20mg/L,其次为多菌灵,克菌丹对花椒炭疽病菌的抑制效果较差,其EC50值为851.14mg/L。因此,苯醚甲环唑和百菌清对花椒炭疽病菌具有较好的抑菌作用,可作为花椒炭疽病的有效防治药剂。
In this study, the mycelial growth rate method was used to determine the antibacterial activities of four high-efficiency and low-toxic bactericides on pepper anthracnose, aiming to provide a theoretical basis for the effective prevention and treatment of pepper anthracnose. The results showed that all four tested fungicides had some inhibitory effects on the mycelium growth of Colletotrichum gloeosporioides, but with significant differences. Among them, difenoconazole and chlorothalonil had strong antibacterial activity with EC50 values of 2.18mg / L and 2.20mg / L respectively, followed by Carbendazim and Captan. Poor, its EC50 value of 851.14mg / L. Therefore, difenoconazole and chlorothalonil have good antibacterial activity against Colletotrichum gloeosporioides and can be used as an effective control agent for pepper anthracnose.
