摘　　要：病毒病是为害辣椒的主要病害之一,影响辣椒的产量和品质。为筛选出防治辣椒病毒病的安全有效药剂,对31%寡糖·吗胍可溶性粉剂、5%壳寡糖水剂、1.5%植病灵水乳剂、2%香菇多糖水剂进行田间药效试验。试验结果表明,31%寡糖·吗胍可溶性粉剂防效最好,辣椒产量和效益最高,5%壳寡糖水剂次之,均对辣椒安全。综合防效、成本、产量和效益考虑,建议生产上在辣椒病毒病始发期优先选用31%寡糖·吗胍可溶性粉剂800倍液和5%壳寡糖水剂800倍液进行叶面喷施,注意交替用药。Virus disease is one of the main diseases of pepper,which affects the yield and quality of pepper.In order to screen out safe and effective agent for controlling pepper virus disease,the field test of 31%oligosaccharide·maguanidine soluble powder,5%chitosan oligosaccharide water solution,1.5%Zhibingling water emulsion and 2%lentinan water solution was carried out.The results showed that 31%oligosaccharide·maguanidine soluble powder had the best control effect,and the yield and benefit of pepper were the highest,followed by 5%chitosan oligosaccharide water solution,which were both safe to pepper.Considering the control effect,cost,yield and benefit,it was recommended that 31%oligosaccharide·maguanidine soluble powder 800 times liquid and 5%chitosan oligosaccharide water solution 800 times liquid could be preferentially select for foliar spraying in the initial stage of pepper virus disease in production,and be sure to alternate medication.
