摘要
采用林间试验,在苹果小吉丁虫幼虫期对受害野苹果树进行不同施药方式和施药浓度的组合处理,探究16%虫线清乳油对野苹果小吉丁虫化学防治效果。试验结果表明,采用打孔注药和输液法施药方式在30 d后校正防效均达到90%以上;采用输液法及施药浓度为1倍稀释时,在整个防治期内校正防效均高于其它处理。对返青率进行比较分析时发现,对于野苹果树生长,最适合的施药浓度为2倍稀释。因此,在虫害防治前期采用1倍稀释浓度、防治后期采用2倍稀释浓度进行施药防治的效果较好。
In order to provide the basis for the comprehensive management to Agrilus mali pets, the control effect of 16% -worm clear- ance EC to Agrilus mall Matsumura, the biggest threaten to Malus sieversii forest protection. The effect of different application meth- ods and pesticide concentration on wild apple trees during the Agrilus mali Matsumura pupal stage was investigated based on 16%- worm clearance EC. The correction control effect of hole injection and transfusion were reached 90% or more after 30 days, when transfusion with 1 fold dilution, the correction control effect were higher than other treatments; the rate of reviving comparative analy- sis found that the most suitable pesticide concentration is 2 fold dilution. The tested fungicides on Agrilus mall Matsumura can play a good control effect. Considering the control effect on Agrilus mali Matsumura and the growing of wild apple trees, the dilution of 1 times to the prevention and later treatment by 2 times dilution.
