| 摘 要： | 采用生长速率法,测定了8种杀菌剂对芒果果腐病原粉红单端孢菌的室内毒力.结果表明,8种杀菌剂对芒果果腐病均有抑制效果,除氟硅唑外,其余7种均可用于防治芒果粉红单端孢菌引起的病害.其中,多菌灵对粉红单端孢菌的抑制效果最好,其EC50和EC75值分别为1.30和3.09 mg·L-1;其次依次为咪鲜胺锰盐、戊唑醇、腈菌唑和醚菌酯；代森锰锌和百菌清对病菌的抑制效果较差.

| Abstract: | The toxicities of 8 fungicides against Trichothecium roseum causing mango fruit rot were tested by mycelial growth rate method. The results showed that the 8 fungicides could inhibit the pathogen of the mango fruit rot efficiently. All the tested fungicides except flusilazole could be used to control the disease caused by T. roseum. The toxicity result was analyzed according to the EC50 value,EC75 value and slope coefficient of toxicity regression equation. The toxicity of carbendazim was the highest against T. roseum with the EC50 value of 1. 30 mg·L-1 and EC75 value of 3. 09 mg·L-1 ,followed by prochloraz-manganese chloride complex,tebuconazole, myclobutanil,kresoxim-methyl. mancozeb and chlorothalonil had the lowest toxicity. |
