Abstract

夏季的高温高湿天气极易诱发豇豆的病害发生，常规的防治方法是喷洒农药。由于豇豆一旦开始结荚，每天都得采摘，加之豇豆喷药时无法将豆荚与植株隔离，这就必然造成豆荚农药的高残留。本发明提供一种乙酸乙醇稀释液配方，可迅速杀灭豇豆病害又不会造成任何有害物质残留，操作人员也无须任何防护措施。

Description

乙酸乙醇防治豇豆病害法
一、技术领域
本发明涉及豇豆栽培技术，特别是涉及通过按一定比例和浓度配制的乙酸乙醇防治豇豆病害的技术。
二、背景技术
夏季的高温高湿天气极易诱发豇豆的病害，常规防治方法都是喷洒农药，然而豇豆一旦开始结荚，每天都得采摘，否则将会造成豆荚老化、走籽，从而降低商品价值，严重的问题在于喷洒农药时根本不可能将豆荚与藤叶隔开，所以夏季菜市场所售豇豆，绝大多数都被农药污染过，其中有一部分是头天打药第二天采摘，甚至严重的还有上午打药下午就采摘的情况。这种情况理应禁止，但在菜农看来，这却是不得已的无奈之举。随着病害对常规农药的抗药性的不断增强，所以农药的毒性和剂量也得不断地升级，以致造成菜市场豇豆的食用安全性越来越成问题。
三、发明内容
本发明的目的是提供一种非农药制剂的，既具良好的豇豆病害防治效果又不会污染豇豆的豇豆病害杀菌剂。
本发明的目的是这样实现的：针对豇豆的煤霉病、白粉病、枯痿病和菌核病，按100kg水加浓度为36％的乙酸1.8～2升，无水乙醇1.5～1.8升的比例配制成乙酸乙醇稀释液，然后对染病豇豆进行全方位喷施，由于乙醇挥发快，所以药液须在喷施前1小时内配制，喷施时机须选在黄昏时进行，七天后再重喷一次。
采用上述方案，可收到如下显著效果：
1、豇豆病害的防治从来都是施用多菌灵、百菌清之类的常规农药，病害对这些农药早已产生一定的抗药性，所以喷施后维持的有效期很短，由于这些病害从未接触过乙酸、乙醇，所以完全无抗性，经连施两次后，可确保豇豆在整个采收期都不再发病。
2、按本方案配制的乙酸乙醇稀释液既不伤害豇豆，又无有害物质残留，操作时无须任何防护措施。
