摘　　要：为明确助剂在植保无人机防控水稻病虫害中的作用,选择火牛、怀农特、杰效利、激健及雅丰5种助剂对稻飞虱、二化螟等“三虫两病”开展了效果评价。结果表明,每667 m^(2)添加怀农特30 mL、杰效利30 mL或激健15 mL 3种助剂能提高药剂防治稻飞虱、二化螟、稻纵卷叶螟和稻曲病的药效,对稻飞虱2次药后20 d防治效果分别为97.09%、97.74%和97.51%,比药剂单用效果提升2.02、2.67和2.44百分点;对二化螟防治效果为73.88%、70.99%和73.81%,比药剂单用效果提升6.17、3.28和6.10百分点;对稻纵卷叶螟防治效果为88.99%、88.43%和89.06%,比药剂单用效果提升1.09、0.53和1.16百分点;对稻曲病防治效果为86.21%、85.93%和88.26%,比药剂单用效果提升0.36、0.08和2.41百分点,但以上3种助剂与药剂单用的防治效果无显著性差异。而防治纹枯病时,每667 m^(2)添加火牛10 mL、怀农特30 mL或雅丰10 mL也能对药剂效果起到一定提升作用,防治效果分别为76.53%、74.11%和73.75%,分别比药剂单用效果提升2.94、0.52和0.16百分点,但相互间不存在显著差异。综上,助剂能一定程度提升植保无人机飞防对水稻病虫害的防治效果,但在每667 m^(2)喷液量2 L的基础上效果不显著。In order to clarify the role of adjuvants in the control of rice diseases and insect pests by spraying drone five adjuvants,including Huoniu,Huainongte,Jiexiaoli,Jijian and Yafeng were selected to evaluate the control effect of"three pests and two diseases"such as rice planthopper and Chilo suppressalis.The results showed that adding 30 mL Huainongte,30 mL Jiexiaoli or 15 mL Jijian per 667 m^(2) could improve the control effect of rice planthopper,Chilo suppressalis,Cnaphalocrocis medinalis,and Ustilaginoidea virens.The control effects of rice planthopper after 20 days of two times of spraying were 97.09%,97.74% and 97.51%,respectively,which were 2.02,2.67,and 2.44 percentage points higher than the single use of the insecticide.The control effects of Chilo suppressalis were 73.88%,70.99% and 73.81%,respectively,which were 6.17,3.28 and 6.10 percentage points higher than the single use of the insecticide.The control effects of Cnaphalocrocis medinalis were 88.99%,88.43% and 89.06%,respectively,which were 1.09,0.53 and 1.16 percentage points higher than the single use of the insecticide.The control effects of Ustilaginoidea virens were 86.21%,85.93% and 88.26%,respectively,which were 0.36,0.08 and 2.41 percentage points higher than the single use of the fungicide.However,there was no significant difference between the control effects of the above three adjuvants and the single use of the insecticide or fungicide.When adding 10 mL of Huoniu,30 mL of Huainongte or 10 mL of Yafeng per 667 m^(2) for Thanatephorus cucumeris,the control effects were 76.53%,74.11% and 73.75%,respectively,which were 2.94,0.52 and 0.16 percentage points higher than those of the single use of the fungicide,but there was no significant difference between them.In conclusion,the adjuvants can improve the prevention and control effect of spraying drone on rice diseases and insect pests to a certain extent,but the effect is not significant on the basis of spraying spraying drone 2 L per 667 m^(2).
