3种新型助剂与30多菌灵·戊唑醇悬浮剂混用对苹果枝干轮纹病的防效评价

摘要

本文通过田间试验，确定了30%多菌灵·戊唑醇SC与施伴、百渗及百湿露3种新型助剂混用后对苹果枝干轮纹病的田间防治效果。结果表明30%多菌灵·戊唑醇 SC 800倍与施伴1500倍、百渗3000倍、百湿露3000倍混用防效分别为78.23%、88.71%、71.77%，不添加助剂的处理30%多菌灵·戊唑醇SC 800倍的防效仅为63.71%。%A field experiment was conducted to study the field control effects of 30% carbendazim·tebucona-zole suspension concentrate mixed with three new adju-vants (Shiban, Baishen, Baishilu) against ring rot dis-ease on stem of apple. The experiment showed that 30% Fulian suspension concentrate (800 times dilution) mixed with Shiban (1500 times dilution), Baishen (3000 times dilution), Baishilu (3000 times dilution) provid-ed 78.23%, 88.71%, 71.7% control efficiency. The con-trol efficiency of 30% carbendazim·tebuconazole suspen-sion concentrate (800 times dilution) without adjuvants was 63.71%.
