0.3%苦·小檗碱·黄酮水剂防治番茄病毒病田间药效试验

以番茄为试材,以20%盐酸吗啉胍铜可湿性粉剂250倍液和0.26%苦参碱水剂500倍液为对照,研究了100、200、300倍液不同浓度0.3%苦.小檗碱.黄酮水剂对番茄病毒病的防治效果。结果表明:0.3%苦.小檗碱.黄酮水剂300倍液、200倍液、100倍液防治番茄病毒病时,防效分别为66.26%、75.50%、79.97%;对照组药剂20%盐酸吗啉胍铜可湿性粉剂250倍液和0.26%苦参碱水剂500倍液防效分别为67.03%和65.79%;供试药剂防效明显高于对照药剂。

Field Trails on Tomato Virus Control with 0.3 ％ Radix Sophorea Flavesentis-Berberine-Flavone Bacteriocide AS

Taking tomato as the experimental material,treated with 20% moroxydine hydrochloride copper acetate wettable powder 250 folds and 0.26% matrine solution 500 folds as control,the control effects of 100 folds,200 folds,300 folds of 0.3% Radix Sophorea Flavesents-Berberine-Flavone Bacteriocide AS on tomato virus disease were studied.The results showed that the effects of control were 67.03% treated with 20% moroxydine hydrochloride copper acetate wettable powder 250 folds and 65.79% treated with 0.26% matrine solution 500 folds,while the results from 0.3% Radix Sophorea Flavesentis-Berberine-Flavone Bacteriocide AS of 300 folds,200 folds and 100 folds were respectively 66.26%,75.50% and 79.97%,which were remarkably higher that the control.
