8种生物源和矿物源农药防治加工番茄细菌性斑点病试验

【目的】研究8种生物源和矿物源农药对加工番茄细菌性斑点病的防治效果,筛选出更加适合番茄制品出口食品安全要求的高效农药。【方法】采用田间小区试验,比较8种生物源和矿物源农药对加工番茄细菌性斑点病防效差异。【结果】第3次施药后7 d各药剂的防效分别为:77%氢氧化铜干悬浮剂73.11%、37.5%氢氧化铜悬浮剂67.43%、波尔多液64.78%、2.0%氨基寡糖素水剂51.14%、4%春雷霉素可湿性粉剂50.38%、3%多抗霉素可湿性粉剂45.46%、0.5%小檗碱水剂43.45%,植物激活蛋白防效最低仅为29.17%。【结论】77%氢氧化铜干悬浮剂、37.5%氢氧化铜悬浮剂和波尔多液3种矿物源农药防效较高,且更适合加工番茄产品出口的食品安全要求。

The Experiment on Using Eight Biologic and Mineral Bactericides to Prevent Bacterial Speckle Disease in Processing Tomato

【Objective】Using eight biologic and mineral bactericides to prevent bacterial speckle disease in processing tomato and screen out effective biologic bactericide which will better meet the requirement for food safety.【Method】Compared the prevention effect of eight biologic and mineral bactericides on bacterial speckle disease in field plot experiment.【Result】Seven days after third using of these bactericides,the prevention effect of 77% cupric hydroxide WP is 73.11%,37.5% cupric hydroxide SC is 67.43%,bordeaux mixture is 64.78%,4% Kasugamicin WP is 50.38%,2% amino oligochitosan AS is 51.14%,3% polyoxin WP is 45.46%,0.5% berberine AS is 43.45%,and plant activation protein is only 29.17%.【Conclusion】The prevention effect of 77% cupric hydroxide WP,37.5% cupric hydroxide SC and bordeaux mixture are better,and they are more suitable for meeting the requirement of food safety for the exporting of processing tomato products.
