通过室内防治效果测定研究几种生物药剂对黄瓜炭疽病、细菌性角斑病的防治效果,获得防治效果较好的生物药剂种类,从而为黄瓜田间防治应用提供依据。试验结果表明:针对黄瓜炭疽病,使用高浓度4%农抗120、木醋液均具有较好抑制效果,且抑制效果超过常规用药70%甲基托布津。针对黄瓜细菌性角斑病,可采用新植霉素、农用链霉素及木醋液;同时,喷施小苏打调节酸碱环境,防治效果最为理想。
To study the effect of several biological agents on the control of anthracnose and bacterial angular leaf spot in cucumber through the determination of indoor control effect and to find out the biological agents with better control effect and thus provide the basis for the cucumber field application. The results showed that: for Cucumber anthracnose, the use of high concentrations of 4% agar 120, wood vinegar has a better inhibitory effect, and the inhibitory effect than conventional use of 70% thiophanate. For bacterial angular leaf disease cucumbers, the use of new phytomycin, agricultural streptomycin and wood vinegar; the same time, spraying sodium bicarbonate regulate acid-base environment, the best control effect.
