柿树炭疽病菌的生物学特性及几种杀菌剂对其的抑制作用
Biological characteristics of Collelotrichum gloeosporioides and inhibitory effects of several fungicides
摘要
Abstract
Biological characteristics of Collelotrichum gloeosporioides was determined by using the crossing method and haemocytometer method. The toxicity of 7 fungicides to C. Gloeosporioides was tested by mycelial growth method. Then the control efficacy of 5 fungicides to C. Gloeosporioides was studied through field trials. The results showed that the optimum temperature of mycelium growth was 20 - 30 ℃, the optimum temperature of sporulation was 25 - 30 ℃, and the optimum pH value was 5 -6. Among the fungicides test,the inhibitory activities of carbendazim,difenoconazole,tebuconazole and flusilazole were very high, with EC50 value of 0. 118 8,0. 138 0,0. 159 9和1. 297 2 μg/mL, respectively. The results of field trials showed that the control efficacy of prochloraz 250 EC(600× ), difenoconazole 100 WG (1000 ×) and tebuconazole 250 EW (1 500×) against C. Gloeosporioides were 89.60% ,88. 56% and 87. 82% .respectively.关键词
