呋喃丹内吸剂农药作为根区施药防治多种农业害虫较之目前常规用法有其许多优点,而引起国内外人们的重视。呋喃丹颗粒剂根区施药是把呋喃丹拌泥做药球深施到植株根部,通过根部吸收,再由植株中的输导组织把药剂自下而上输送到植株各部。因此,根区施药至呋喃丹农药出现在褐稻虱取食部位——植株基部叶鞘内,要有一定的时间。为了探索呋喃丹一次根区施药防治连晚二至四代褐稻虱的适期,我们进行了试验。
Carbofuran inhalation pesticides as a root zone pesticide application prevention and control of many kinds of agricultural pests compared to the current conventional usage has its many advantages, which aroused the attention of people at home and abroad.
