10%噻虫嗪微囊悬浮剂拌种防治花生蛴螬田间药效试验
|
摘要
[目的]筛选防治花生蛴螬的10%噻虫嗪微囊悬浮剂拌种的最佳剂量,为该制剂的进一步推广应用提供参考。[方法]通过田间小区试验,比较100 kg种子采用10%噻虫嗪微囊悬浮剂1 200、1 800、2 400 g,30%毒死蜱微囊悬浮剂(对照药剂)1 800 g拌种及空白对照5个处理条件下的防虫和保果效果,研究10%噻虫嗪微囊悬浮剂拌种对花生田蛴螬的安全性、防治效果及最适使用剂量。[结果]10%噻虫嗪微囊悬浮剂拌种防治花生田蛴螬的效果较好,且在设计剂量范围内,随着10%噻虫嗪微囊悬浮剂剂量的增加,防虫和保果效果均有所提高,其中,100 kg花生种子使用10%噻虫嗪微囊悬浮剂2 400 g拌种,防虫和保果效果均最佳。[结论]综合考虑,100 kg花生种子使用10%噻虫嗪微囊悬浮剂2 400 g拌种,可有效防治花生田蛴螬。
[Objective] To screen the optimum dosage of 10% thiamethoxazine microcapsule suspension for the control of peanut grubs and to provide reference for its further popularization and application. [Method] Field plot experiments were conducted to compare the insect control and fruit preservation effects of 10% thiamethoxazine microcapsule suspension on peanut grubs under five treatments: 1 200, 1 800, 2 400 g, 30% chlorpyrifos microcapsule suspension(control agent) 1 800 g and blank control. The safety, control effect and optimal dosage of 10% thiamethoxazine microcapsule suspension on peanut grubs were studied. [Result] The effect of 10% thiamethoxazine microcapsule suspension seed dressing on controlling peanut grubs in the field was better, and within the designed dose range, with the increase of 10% thiamethoxazine microcapsule suspension dose, the effect of insect prevention and fruit preservation was improved. Among them, 2 400 g thiamethoxazine microcapsule suspension seed dressing with 10% thiamethoxazine was used for every 100 kg of peanut seeds, and the effect of insect prevention and fruit preservation was the best. [Conclusion] Taking into account, 10% thiamethoxazine microcapsule suspension 2 400 g per 100 kg of peanut seeds can effectively prevent and control the adverse effects of grubs on peanut production.
