[目的]研究4种甲氧基丙烯酸酯类杀菌剂对马铃薯、番茄、黄瓜保健增产效应,探索4种杀菌剂无病害压力下保健增产的有效起始剂量或饱和剂量存在范围及保健增产的幅度。[方法]供试药剂共4种,每种药剂设2个浓度。通过田间试验,调查了每个处理马铃薯、番茄及黄瓜的产量或优质率。[结果]烯肟菌胺、烯肟菌酯、唑菌酯与唑胺菌酯对马铃薯、番茄、黄瓜保健增产有效起始剂量应低于133 mg/L;对马铃薯、黄瓜保健增产的饱和剂量应低于666.7 mg/L。烯肟菌胺与唑菌酯使番茄保健增产的饱和剂量应低于667 mg/L。[结论]烯肟菌胺、烯肟菌酯、唑菌酯及唑胺菌酯3种杀菌剂对马铃薯、番茄及黄瓜均具有明显的保健增产效应,值得推广。
[Objective] The research aimed to study the effects of four kinds of methoxyacrylate fungicides on the health-promoting effects of potato, tomato and cucumber and explore the effective starting dose or saturated dose range of health-promoting yield under the no-disease pressure of four fungicides and the extent of health increase . [Method] A total of 4 kinds of test agents, each concentration of 2 agents. Through field trials, the yield or quality of each treatment of potatoes, tomatoes and cucumbers was investigated. [Result] The effective starting dose for the health increase of potato, tomato and cucumber should be less than 133 mg / L. The saturated dose of health benefit to potato and cucumber Should be lower than 666.7 mg / L. The saturated dose of dimethoate and pyraclostrobin to tomato should be less than 667 mg / L. [Conclusion] The three fungicides including netilmicylamine, enoximyloxacillin, pyraclostrobin and pyraclostrobin have significant health effects on potato, tomato and cucumber, which are worth popularizing.
