- 摘要:
- 以番茄灰霉病菌田间发病叶片为试材，采用菌丝生长速率法，研究了11种杀菌剂对番茄灰霉病菌的影响，选择其中较好的8种药剂进行田间药效试验。结果表明：室内毒力测定中25%咪酰胺EC对番茄灰霉病菌的毒力最强，其EC50值为0.0397 μg/mL；40%嘧霉胺SC、40%百菌清SC和80%代森锰锌WP对番茄灰霉病菌也具有较好的抑制效果。田间试验结果中25%咪酰胺EC、28%烯肟?多菌灵WP、50%啶酰菌胺WG和50%异菌脲SC对番茄灰霉病表现较高的防效，防效分别为85.57%、82.68%、80.92%和73.34%。该试验筛选出了对番茄灰霉病具有较好防效的药剂，对番茄灰霉病的药剂防治具有重要的指导意义。
- Abstract:
- Taking disease leaves which infected by Botrytis cinerea in the field as materials,the toxicity of 11 fungicides against Botrytis cinerea were tested by mycelium growth rate method in laboratory，and 8 fungicides with better efficiency were selected to test in the field.The results showed that,in laboratory that 25% prochloraz EC had the best toxicity against Botrytis cinerea，of which the EC50 value was 0.0397 μg/mL.40% pyrimethanil SC，40% chlorothalonil SC and 80% mancozeb WP also had better toxicity to Botrytis cinerea. The results of field trials showed that 25% prochloraz EC，28% ene oxime carbendazim WP，50% boscalid WG and 50% iprodione SC had high control effect，which were 85.57%，82.68%，80.92% and 73.34%，respectively.The effective fungicides were screened out，which provided an important directive to control the disease.
