不同药剂防治烟蚜及烟草黑胫病试验研究

Experiment on Control of Myzus persicae (Sulzer)and Tobacco Black Shank with Several Chemicals

摘要: 对按一定比例配制的吡虫啉WP与甲霜灵锰锌WP的复配剂进行了田间药效试验研究。结果表明:所用复配剂3个浓度对烟蚜及烟草黑胫病均有很好的防治效果,且与各对照单剂吡虫啉,甲霜灵锰锌防效差异不显著。从综合防效及降低药剂成本等因素考虑,以复配剂3 000g/hm²的效果最理想。

Abstract: A field experiment was conducted on control Myzus persicae (Sulzer)and tobacco black shank with composite chemicals of 10% imidacloprid WP and 58% metalaxyl-mancozeb WP at certain proportions. All of the tested 3 levels of the composite chemicals showed good control effects. Balanced control effects with the cost, the composite chemicals applied in 3 000g per ha was suggested.
