摘　　要：药剂拌种技术近年来在我国各地得到大力推广,是农作物病虫害防治的重要技术之一.药剂拌种技术具有用药量小、防治成本低、对病虫害防效高、对环境友好和能达到一药多治的优点,是当前农作物病虫害防治工作中实现减药增效绿色控害的重要举措.本研究测定了拜耳作物科学(中国)有限公司提供的24.1%肟菌·异噻胺种子处理悬浮剂(入田?)+60%吡虫啉悬浮种衣剂(高巧?)+0.136%赤·吲乙·芸可湿性粉剂(碧护?)拌种药剂组合对水稻病虫害与生长发育的影响.结果表明,示范区药剂拌种对水稻苗期至分蘖期和生长中后期主要病虫害防效显著,且比常规区减少农药施用1次以上,并能促进稻株健壮生长,增多有效穗数,提高结实率,促进高产稳产,减药增效效果明显,值得大面积推广.Seed dressing technology is one of the important technologies for crop disease and pest control,which has been widely promoted throughout China in recent years.Seed dressing technology has advantages of small dose,low cost,high efficiency,environment friendly and multiple treatments with one pesticide.It is also an important measure to realize the reduction of pesticide use,increase efficiency and green control in the current crop disease and pest control.In this study,the effects of the combination of 24.1%oxime·isothiamide seed treatment suspension(Rutian)+60%imidacloprid seed suspension coating(Gaoqiao)+0.136%Chimadium-indum-yun wettable powder(Bihu)on rice diseases and pests,the growth and development of rice were determined.The results showed that the combination of seed dressing agents in demonstration area had significant control effect on main diseases and insects from seedling stage to tillering stage,and in the middle and late stages of rice growth,and reduced use of pesticides more than once than that in the conventional area.It also could promote robust growth of rice plant,increase number of effective panicles,improve seed setting rate,promote high and stable yield.The effects of reducing pesticide application and increasing efficiency was obvious.It is worth to promote in large scale of production.
