FANGZHIFANGFA:

农业措施:一是轮作换茬,合理轮作换茬能减轻为害,可采取稻瓜轮作等形式。二是整地前灌水浸泡一段时间,清除棚内棚外杂草,加强水肥管理,使植株生长旺盛,可减轻危害。

物理防治:挂黄色或蓝色粘虫板进行物理防治。

化学防治:①25%阿克泰(噻虫嗪)3000倍;②2.5%菜喜(多杀霉素)800-1000倍;③10%除尽(虫螨腈)1200倍;④6%爱绿士(乙基多杀霉素) 1200倍;⑤15%唑虫酰胺1200倍。

为害特点:网上兼职赚钱指南若虫和成虫在叶背吸食汁液,使叶片失绿变黄变白,影响光和产物的形成,严重时叶片干枯,甚至整株死亡。

防治方法:

物理防治:网上兼职赚钱指南作物收获后,彻底清除田间杂草和茎蔓落叶,消灭上茬虫源。

化学防治:网上兼职赚钱指南发生初期,用20%哒螨灵1500倍或1.8%阿维菌素3000倍喷雾。

生物防治:在“红蜘蛛”发生初期,释放智利小植绥螨进行防治,按照益害比1∶20或者3000头-9000头/亩;2周后再释放一次,可有效控制叶螨为害。叶螨发生严重时,选择中心株释放,按照60头/株释放智利小植绥螨。释放时连同介质一起撒在叶片表面,注意在捕食螨应用期间避免使用杀虫、杀螨剂。
