三十七种生物农药对西瓜细菌性果斑病菌的室内抑菌效果测定

Antibacterial Activity Evaluation of 37 Biological Pesticides in vitro Against Acidovorax citrulli on Watermelon

以37种生物药剂和西瓜细菌性果斑病菌为试材,采用抑菌圈法研究37种生物药剂对西瓜细菌性果斑病菌的抑菌效果。结果表明:80%乙蒜素EC(消菌剑魔)、80%乙蒜素EC(汉翔)、3 000亿个/g荧光假单胞杆菌DP、0.15%四霉素AS 4种药剂对西瓜细菌性果斑病菌室内抑菌效果较好。该研究筛选出了对西瓜细菌性果斑病具有一定防效的生防药剂,对西瓜细菌性果斑病的科学防治具有指导意义。

The antibacterial activity of 37 biological pesticides against Acidovorax citrulli（Ac）were tested by the method of bacteriostatic circle.The results showed that the growth of Ac was obviously inhibited by 4biological pesticides including ethylicin 80% EC,Pseudomonas fluorescens,three hundred billion/g DP and tetramycin 0.15% AS.Four effective biological pesticides were determined,which was an important directive to scientific prevention and treatment of the disease.
