選對(duì)路農(nóng)藥滅多威硫雙威的品種
date:2017/3/4   
首先要請(qǐng)有經(jīng)驗(yàn)的農(nóng)技人員到大田實(shí)際查看病蟲(chóng)害情況后“對(duì)癥下藥”,避免盲目亂用農(nóng)藥造成藥害或貽誤防治時(shí)機(jī)。其次,在保證藥效的前提下,嚴(yán)禁選高毒農(nóng)藥品種!皢(wèn)題豇豆”是因使用高毒有機(jī)磷農(nóng)藥“水胺硫磷”引起,“毒韭菜”使用了高毒有機(jī)磷農(nóng)藥“甲拌磷”所致,“毒生姜”是使用劇毒農(nóng)藥“涕滅威”所致等。所以,要優(yōu)先選擇高效、低毒、低殘留農(nóng)藥,最好選生物農(nóng)藥。
