新疆巴旦杏产区吐伦球坚蚧药剂防治试验及经济效益分析初报

Studies on Experiment of Comprehensive Control and Economic Benefits Analysis on Rhoaococcus turanicus Archangelskaya in Xinjiang Almond Growing District

【目的】在新疆巴旦杏产区进行吐伦球坚蚧田间药效试验和经济效益分析,为科学有效防治提供依据。【方法】在若虫期开展不同药剂防治小区试验。【结果】植物源杀虫剂300倍液、600倍液和900倍液防效分别为94.8%、93.8%和93.4%。丙溴磷防效为89.9%,丙溴磷+一可佳防效为91.3%,噻杀扑防效为94%,噻杀扑+一可佳防效为94%,蚧绝防效为93.8%,蚧绝+一可佳防效为94%。使用40%蚧绝、20%噻杀朴和丙溴磷处理后的巴旦杏产量比不防治分别高出34.6%、34.4%和34%,挽回经济损失分别为95.1%、94.3%和92.7%。【结论】供试的几种药剂对吐伦球坚蚧若虫均有较好的防治效果,防效均达到90%以上。各药剂处理比非防治田平均增产34.3%。

[Objective]The project aimed to conduct field trials and economic analysis to provide the basis for scientific prevention and treatment. [ Method] Different insecticides were used to carry out preventive treatment experiment in nymphal stage. [ Result] Control efficiency of botanical insecticides 300 mult multiple was 94.8%, 600 muh multiple were 93.8%, and 900 mult multiple were 93.4%. Control efficiency of profenofos was 89.9% , profenofos ＋ Yikejia was 91.3% , Saishapu was 94%, Saishapu ＋ Yikejia was 94% , Jiejue was 93.8% , Jiejue ＋ Yikejia was 94%. The output of almond treated with 40% Jiejue, 20% Saishapu and Profenofos was 34.6% ,34.4% and 34% than the one without prevention. 95.1% , 94.3% and 92.7% of economic loss were retrieved respectively. [ Conclusion ] The test of several pesticides on nymphs of Rhoaococcus turanicus Archangelskaya revealed good control effect, and the control efficiency reached 90%. On average, the yield from the fields treated with pesticide was 34.3% than that from the non - treatment fields.
