一是药液量要足。一般情况下稻飞虱喜欢躲在禾苗基部。因此,在施药时注意多打药水,使药液流到禾苗基部,触杀稻飞虱。一般每亩喷施叶蝉散、速灭威、扑虱灵等药液60～70公斤。不但喷施足够的药液,还注意将药液喷均匀,尽可能将药液喷到虫体上,这样可提高防治效果。二是喷药时田间要有水层。喷药时田内一般都保留3～4厘米水层,施药后3～5天内不排水、不过水、不灌水。田里有水,飞虱易被杀死,未被杀死的,也会掉进水里中毒而亡。
First, the amount of liquid medicine to foot. Under normal circumstances planthopper like hiding in the seedlings base. Therefore, pay more attention when playing drug syrup, so that the liquid flow to the base of seedlings, touch planthoppers.
