以蒙古黄芪为试材，采用杀虫剂与底肥混合后撒施+杀菌剂根部浸苗的方法，在种苗插播时进行药剂处理，以清水（不施药）为对照，研究了6种杀菌剂〔1%申嗪霉素SC 300倍液、37%翠甲（苯醚甲环唑） WG 300倍液、3亿cfu/g哈茨R木霉菌WP 120倍液、62.5克/升亮盾（精甲·咯菌腈） FSC 500倍液、10亿cfu/g多粘类芽孢杆菌FG 300倍液、3%甲霜·恶霉灵AS 500倍液〕与2种杀虫剂〔10豫福满仓（噻唑膦） GR 22.5 kg/hm2、5%阿维·毒死蜱GR 45 kg/hm2〕复配施用对黄芪安全性、根腐病田间防治效果、黄芪商品产量和种植收益的影响。结果表明：杀菌剂与杀虫剂配合施用均对黄芪安全，且均对黄芪根腐病具有一定的防治效果，虽然增加了购药成本，但生产出的黄芪商品率和产量均有提高且绿色安全，最终扣除施药成本后的经济效益提高。其中，10%噻唑膦GR 22.5 kg/hm2与底肥混施+1%申嗪霉素SC 300倍液浸苗处理的黄芪根腐病发病程度最低、防治效果最好，商品率、商品产量和扣除施药成本后的净收入最高，效果最好。该处理下，黄芪被害指数仅3.26豫，根腐病防治效果为80.87豫，商品率100豫，商品产量（5914.62 kg/hm2）和净收入（113292.6元/hm2）分别较清水对照提高54.76豫和72.23豫。%The pesticide mix ed with base fertilizer were applied to the field and the seedling root was soaked with fungicide,the effects of compounding of 6 fungicide and 2 insecticide on safety,control effi-ciency of root rot disease,commodity output and economic benefits of A stragalusm embranaceus (Flsch) Bge were studied. The results showed that cooperation application of fungicide and insecticide could effectively control the root rot disease,increase the commodity rate and yield and economic benefit of A stragalusm em-branaceus, and it was safety. Among them,the effect of 10% fosthiazate GR 22.5 kg/hm2 combined with 1% phenazino-1-carboxylic acid SC 300 times liquid was best,under the treatment,the damage index was 3.26%,root rot control effect was 80.87%,commodity rate was 100%,the yield and the income after de-ducting the cost of spraying were 5 919.63 kg/hm2 and 113 292.6 yuan/hm2,compared with the water control which were increased by 54.76% and 72.23%.
