异菌脲和噻呋酰胺对花生白绢病的田间防效
|
摘要
[目的]探索花生白绢病的有效防控途径。[方法]采用喷淋植株根茎部方法,研究异菌脲和噻呋酰胺对花生白绢病的防治效果、安全性以及对花生产量的影响。[结果]异菌脲和噻呋酰胺对花生正常生长无不良影响,安全性好。50%异菌脲SC在施用量为1 200～3 000 mL/hm~2时对花生白绢病的株防效为44.6%～68.7%,增产效果为14.1%～66.5%;24%噻呋酰胺SC在施用量为750～1 050 mL/hm~2时对花生白绢病的株防效为66.1%～79.4%,增产效果为64.9%～69.9%。[结论]采用适宜药量,异菌脲和噻呋酰胺可有效控制花生白绢病危害,增产显著,值得推广。
[Objective] The aim was to explore effective prevention and control approach for peanut white silk disease. [Method] We took spraying plant roots and stems method to study control effect and safety of iprodione and thifluzamide against peanut white silk disease and effect on peanut yield. [Result] The iprodione and thifluzamide was safe to peanut. When the dosage of 50% iprodione SC was 1 200-3 000 mL/hm~2,the plant control effect of iprodione against peanut white silk disease was 44.6%-68.7%,and the yield-increasing effect was 14.1%-66.5%. When the dosage of 24% thifluzamide SC was 750-1 050 mL/hm~2,the plant control effect of thifluzamide against peanut white silk disease was 66.1%-79.4%,and the yield-increasing effect was 64.9%-69.9%.[Conclusion] If the dosage is suitable,iprodione and thifluzamide can effectively control the damage of peanut white silk disease,increase yield obviously,so they are worth promoting.
