摘　　要：生物源农药对作物病虫害有较好的防治效果,可有效代替部分化学农药,是农药行业研究新方向。以喷施清水为对照,选取丁子香酚、香芹酚和多抗霉素3种生物源农药及霜脲·锰锌化学药剂为研究对象,对马铃薯不同时期进行喷施处理,比较4种农药对马铃薯早疫病、晚疫病、黑痣病和疮痂病的防治效果。结果表明,在该作物早疫病防效上,4种农药防效排名为香芹酚>霜脲·锰锌>多抗霉素>丁子香酚;在晚疫病防效上排名为香芹酚>丁子香酚>霜脲·锰锌>多抗霉素;在黑痣病防效上排名为香芹酚>丁子香酚>多抗霉素>霜脲·锰锌;在疮痂病防效上排名为霜脲·锰锌>香芹酚>丁子香酚>多抗霉素。综上表明,对比3种生物源农药和霜脲·锰锌在4种马铃薯病害上的综合防治效果,发现香芹酚表现最好。本文为探索生物源农药的施用方法,减少化学农药施用剂量,以及推广马铃薯绿色综合防控技术提供参考。Biogenic pesticides have a good control effects on crop diseases and pests,and can effectively replace some chemical pesticides,which is a new research direction in the pesticide industry.3 biological pesticides,eugenol,carvacrol,and polyoxin,as well as fipronil manganese zinc chemicals,were selected as the research objects to spray potatoes at different periods,and the control effects of the 4 pesticides on potato early blight,late blight,black scurf and scab disease were compared.The experimental results showed that in terms of early blight control efficiency of the crop,the control efficiency of the 4 pesticides was ranked as carvacrol>fipronil manganese zinc>polyoxin>eugenol;in terms of late blight prevention effectiveness,the order was carvacrol>eugenol>fipronil manganese zinc>polyoxin;in terms of black scurf prevention effectiveness,the order was carvacrol>eugenol>polyoxin>fipronil manganese zinc;in terms of scab disease prevention effectiveness,the order was fipronil manganese zinc>carvacrol>eugenol>polyoxin.In conclusion,comparing the comprehensive control effect of three biological pesticides and fipronil manganese zinc on 4 diseases,carvacrol was found to be the best.This article provides references for exploring the application methods of bio-derived pesticides,reduce the dosage of chemical pesticides,and promoting the green integrated control technology of potato.
