摘要:

【目的】研究杀虫剂减量施用及添加助剂对红枣-小麦间作麦田蚜虫防效的影响,为杀虫剂减施提供科学依据。【方法】采用随机区组设计,定点调查各处理施药前后麦蚜的种群数量,评价5种常用杀虫剂减施及添加增效剂‘激健’对红枣-小麦间作麦田蚜虫防效的影响。【结果】药后7 d,22%噻虫·高氯氟SC减量20%~40%对麦蚜的防效为91.88%~94.22%,22%氟啶虫胺腈SC减量20%~40%对麦蚜的防效为89.30%~94.11%,70%噻虫嗪WG减量20%~40%对麦蚜的防效为80.08%~83.82%,与常规用量相比均无显著差异。供试药剂减量20%~40%时添加增效剂‘激健’对麦蚜的防效无显著影响。【结论】7 d内对麦蚜的控制达到较高水平,选择22%噻虫·高氯氟SC、22%氟啶虫胺腈SC或70%噻虫嗪WG减施40%人工喷雾即可。14 d内维持较好效果,5种杀虫剂减量施用20%~40%均可。在新疆南疆红枣-小麦间作田内人工喷雾防治小麦蚜虫时,可不添加。

Abstract:

【Objective】 This research aims to evaluate the effectiveness of reduced pesticides application and adjuvant addition in the control of wheat aphids in jujube-wheat intercropping, and to provide a theoretical basis for the scientific use and dosage reduction of pesticides to control the desease. 【Methods】 A randomized block design was used to conduct a fixed plant survey‘Jijian’ to verify the effects of different reduction proportions of five commonly used pesticides and adjuvant addition on the control effect of wheat aphids in jujube-wheat intercropping system. 【Results】 7 d after pesticides application, the control effects against wheat aphids of 20%-40% reduction dosage treatments of 22% thiamethoxam-lambda-cyhalothrin SC, 22% sulfoxaflor SC and 70% thiamethoxam WG were 91.88%-94.22%, 89.30%-94.11% and 80.08%-83.82%, respectively, which had no significant difference compared to the corresponding regular dosage treatment. The control effect of 20%-40% reduction dosage treatments within adjuvant ‘Jijian’ against wheat aphids were not significantly improved compared with the treatments without any adjuvants. 【Conclusion】 If pursuing a relative higher control effects within 7 d, 40% reduction dosages of 22% thiamethoxam-lambda-cyhalothrin SC, 22% sulfoxaflor SC and 70% thiamethoxam WG can be chosen to spray manually. To maintain a better control effect within 14 d, 20%-40% reduction dosages of tested five pesticides can achieve the purpose. When manually spraying pesticides to control wheat aphids in jujube-wheat intercropping fields in South Xinjiang, adjuvant ‘Jijian’ adding is not necessary.
