Abstract

Abstract:

In order to screen safe and effective acaricides for the control of Oligonychus ununguis （Jacobi） and clarify the control effect and cost of plant protection UAV spraying， six acaricides were screened by indoor and field tests. The results showed that the dilution of 20% avermectin·spirodiclofen SC with 1 000 times had the best control effect aganist O. ununguis， and the control effect on 3 and 14 d after treatment were 100% and 97.80%， respectively. 24% Spirodiclofen SC+40% propionate EC diluted by 3 000+550 times， 36% bifenazide·spiromite SC diluted by 2 500 times and 10% abamectin SC diluted by 7 000 times could also provide good control effects， which the control effects after treatment 1，3 and 14 d were ranged 88.59%~99.39%. The screened formulations had the characteristics of quick response and long duration， which could be rotated and used alternately in agricultural practice. When drone spraying was applied to spray the dilution of 20% avermectin·spirodiclofen SC diluted by 1 000 times （the dose rate of effective ingredient was 136 g·hm^-2）， and orange peel oil was added to the spraying solution with the rate of 450 mL·hm^-2， the control effect could reach more than 97% after 14 d. Compared with electric knapsack spraying and engine-operated portable sprayer spraying， the cost of drone spraying could be saved by 38.93% and 45.24%， respectively.

摘要：

为了筛选对防治板栗红蜘蛛安全有效的杀螨剂以及明确植保无人机喷药的防治效果和防治成本，选用6种杀螨剂进行室内及田间小区试验。结果表明，通过室内和田间杀螨剂筛选试验，20%阿维·螺螨酯悬浮剂1 000倍稀释液对板栗红蜘蛛的防效最好，药后3和14 d的防效分别为100%和97.80%；其次为24%螺螨酯悬浮剂和40%丙溴磷乳油分别稀释3 000和550倍、36%联肼·螺螨酯悬浮剂2 500倍稀释液和10%阿维菌素悬浮剂7 000倍稀释液，其药后1、3、14 d的防效达88.59%~99.39%。筛选出的药剂组合具有见效快、药效时间长的特点，在生产上可以轮换、交替使用。使用植保无人机喷施20%阿维·螺螨酯悬浮剂1 000倍稀释液（有效成分用药量为136 g·hm^-2），加入450 mL·hm^-2橙皮精油助剂，其14 d防效可达到97%以上，相比人工背负式电动喷药雾和人工拖管机械喷雾分别可节约成本38.93%和45.24%。
