为减轻豇豆白粉虱的发生,减少化学农药用量、残留和环境污染,采用测报调查、随机区组设计和统计分析等方法,开展了化学农药呋虫胺、啶虫脒和吡蚜酮,生物农药阿维菌素防治豇豆温室白粉虱农药田间药效试验。结果表明:在温室大棚秋季豇豆白粉虱发生较重情况下,每1.8%阿维菌素EC 375 g/hm~2、20%呋虫胺SP(护瑞)600 g、5%啶虫脒WP 600 g、25%吡蚜酮WP 600 g(对照药剂),5~8天施药1次,连续施用3次,药后7、14、20 d,防治效果分别达90.9%、97.0%、88.0%、93.9%,97.4%、92.1%、84.2%、89.4%和95.6%、86.7%、82.2%、84.5%,且药后7 d呋虫胺与阿维菌素和吡蚜酮,极显著高于啶虫脒,阿维菌素与啶虫脒和吡蚜酮之间差异不显著;药后14 d,阿维菌素与呋虫胺和吡蚜酮差异不显著,极显著高于啶虫脒,呋虫胺与吡蚜酮差异不显著,显著高于啶虫脒;药后20 d,阿维菌素极显著高于呋虫胺、啶虫脒和吡蚜酮,呋虫胺与啶虫脒和吡蚜酮差异不显著。同时,生物农药阿维菌素在药后7 d,防效稍低于化学农药呋虫胺,药后14d,防效高于呋虫胺,药后20d,防效极显著高于呋虫胺。这4种药剂尤其是生物农药阿维菌素不仅可以作为防治温室白粉虱的理想药剂,而且可以作为现代农业示范区、无公害农产品、绿色农产品和有机农产品的理想药剂。 In order to reduce the occurrence of cowpea whiteflies and reduce the amount of chemical pesticides, residues and environmental pollution, chemical pesticides such as dinotefuran, acetamiprid and pymetrozine, biological pesticides Efficacy of abamectin against cowpea greenhouse whitefly pesticides in the field. The results showed that: in the greenhouse greenhouse fall in the case of whitefly occurred in the case of avermectin 1.8% abamectin EC 375 g / hm ~ 2, 20% of dinotefuran SP (Carefree) 600 g, 5% acetamiprid WP 600 g, 25% pymetrozine WP 600 g (control agent), applied once a day for 5-8 days, applied three times continuously, and the control effect reached 90.9%, 97.0% and 88.0 %, 93.9%, 97.4%, 92.1%, 84.2%, 89.4% and 95.6%, 86.7%, 82.2% and 84.5% respectively, and the results showed that dinotefuran and avermectin and pymetrozine were extremely high There was no significant difference between acetamiprid, avermectin, acetamiprid and pymetrozine. On the 14th day after treatment, there was no significant difference between abamectin and dinotefuran and pymetrozine, which was significantly higher than that of acetochlor Amidine, dinotefuran and pymetrozine were not significantly different, significantly higher than acetamiprid; after 20 d, the avermectin was significantly higher than those of dinotefuran, acetamiprid and pymetrozine, dinotefuran and pyridine There was no significant difference between acetamiprid and pymetrozine. At the same time, the biopesticide avermectin 7 d after the drug, the control effect was slightly lower than the chemical pesticide dinotefuran, 14 d after the drug, the control effect was higher than dinotefuran, 20 d after the drug control effect was significantly higher than the dinotefuran . These four kinds of agents, especially the biological pesticide avermectin, can not only be used as ideal medicaments for controlling whiteflies in the greenhouse, but also can be used as ideal pesticides for modern agricultural demonstration areas, pollution-free agricultural products, green agricultural products and organic agricultural products.
