一要注意选用内吸性强的农药如乐果、氧化乐果、久效磷、甲胺磷、磷铵、杀虫脒、叶枯灵、稻瘟净、多菌灵、敌菌灵、托布津、粉锈宁、乙磷铝、甲霜安、三环唑、粉唑醇等。这类农药通过作物茎叶吸收后,能迅速传导至植株的各个部位,其药效受降雨影响较小。1605、甲基1605、敌百虫、抗蚜威、喹硫磷、灭幼脲、功夫菊酯、代森铵等农药,虽然没有内吸传导作用,但在作物表面具有较强的渗透力和抗冲刷能力,因而也适合在雨季施用。据报道,叶枯灵施于作物叶面2小时,即能产生内吸传导作用;磷铵施用后能迅
One should pay attention to the selection of strong absorption of pesticides such as dimethoate, omethoate, monocrotophos, methamidophos, ammonium phosphate, chlordimeform, folic acid, rice blast net, carbendazim, propidium, propofol Bujin, triadimefon, Cephalosporin, mefenamide, tricyclazole, flutriafolol and the like. These pesticides absorbed through the stems and leaves of crops, can quickly transfer to all parts of the plant, the efficacy of less affected by rainfall. Pesticides such as 1605, methyl 1605, trichlorfon, pirimicarb, quetiapine, chlorbenzuron, cyhalothrin and methenammonium have strong osmotic forces on the crop surface, although they have no internal conduction and Anti-erosion ability, which is also suitable for application in the rainy season. It is reported that Ye Kueling applied to the foliage of crops 2 hours, which can produce internal conduction conduction; ammonium phosphate quickly after administration
