| 摘 要： | 大同及周边地区洋葱种蝇一年发生3代,以蛹越冬,5月初成虫始见,10月中下旬结束。传统育苗移栽的定植期、洋葱小鳞茎形成期及管状叶形成期为种蝇为害高发期。采取顶凌直播可有效避开种蝇为害高发期,减少用药次数。用50%辛硫磷适时小剂量灌根,配合1.8%虫螨克或10%吡虫啉2000倍液喷施,可替代传统剧毒农药对硫磷(1605)大剂量灌根,实现洋葱安全生产。

| Abstract: | Onion fly in Datong and its neighbouring area has three generations in a year and it overwinters in form of pupa.Its adults appear in May and disappear at the end of October.Its high infection happens at seedling nursing and fix-planting period,or at the formation stage of the young bulb or the tube-like leaf.Therefore,direct sowing in earlier spring could effective avoid the high infection and reduce chemical application frequency.The experiment result showed that,on purpose of vegetable safe production,the traditional high poision big dosage phoxim 1605 onion root drenching could replaced by small dosage root drenching of 50% at proper time combined with 1.8% Avermectin or 10% Imidacloprid spraying. |
