摘要:

【目的】筛选新疆棉田防治棉蚜的最佳药剂与助剂组台,探究其对无人机变量施药防治效果,为无人机精准变量施药防控棉蚜提供依据。【方法】通过田间药效试验,比较不同药剂添加5种喷雾助剂后对棉蚜防效,同时依据试验地生成的处方图开展棉田无人机变量施药作业,测定20%螺虫乙酯·呋虫胺悬浮剂添加倍达通后的理化性质和无人机变量施药防治棉蚜的效果。【结果】20%螺虫乙酯·呋虫胺悬浮剂添加倍达通的防效最高,药后7 d,虫口减退率达到86%,22%噻虫·高氯氟添加倍达通次之,为81%,二者差异不显著,但与其余处理之间有明显差异(P<0.05);无人机变量喷施20%螺虫乙酯·呋虫胺悬浮剂与倍达通组合在4个蚜害等级区均有较好的防治效果,其中危害程度4级、用药量为30 L/hm2时的防效最佳,药后7 d,虫口减退率达到91.14%,其药液覆盖率、雾滴密度分布均匀度和雾滴密度分别为133%、87%和26.28个/cm2,与其他处理有显著差异(P<0.05)。【结论】无人机喷施杀虫剂防治棉蚜的药剂和助剂的最佳组合是20%螺虫乙酯·呋虫胺悬浮剂添加倍达通助剂,当危害程度达到4级、用药量30 L/hm2时的变量作业防治棉蚜的效果最佳。

Abstract:

【Objective】 This project aims to screen the optimal combination of pesticides and adjuvants for cotton aphid control in Xinjiang cotton field and its impact on the variable application by plant protection unmanned aerial vehicles (UAV). 【Methods】 Through the field efficacy experiment, the control effect of five spray auxiliaries added to different pesticides on Aphis gossypii was compared, and the physicochemical properties of 20% spirotetramat · dinotefuran suspension concentrate added with Beidatong and the control effect of UAV variable application on cotton aphids were measured. 【Results】 After adding 5 types of adjuvants, the control effect on Aphis gossypii was improved. Among them, 20% spirotetramat · dinotefuran suspension concentrate added with Beidatong had the strongest control effect, and the reduction rate of insect population reached 86% after 7 days of treatment, followed by the addition of 22% thiamethoxam·lambda-cyhalothrin suspension concentrate added with Beidatong, which was 81%. The difference between the two was not significant (P<0.05). According to the prescription map generated by the experimental site, the cotton field unmanned aerial vehicle variable spraying operation was carried out. The results showed that the combination of 20% spirotetramat · dinotefuran suspension concentrate added with Beidatong showed good control effects in four aphid infestation levels by UAV variable spraying. The optimal control effect was achieved when the level of harm was 4 and the dosage was 30 L/hm2. After 7 days of treatment, the insect population reduction rate reached 91.14%, and the drug coverage rate, droplet density distribution uniformity, and droplet density were 133%, 87%, and 26.28 number/cm2, respectively, with significant differences compared to other treatments (P<0.05). 【Conclusion】 The optimal combination of insecticides and adjuvants for the control of Aphis gossypii is 20% spirotetramat · dinotefuran suspension concentrate added with Beidatong by UAV. The variable operation with a hazard level of 4 has the best effect on the control of cotton aphids. The research results provide scientific basis for the precise application to control cotton aphids of variable pesticides by UAV variable spraying.
