呋喃丹(Furadan;2,3—二氢化—2,2—二甲基—7—苯并呋喃基氨基甲酸酯)是一种内吸杀虫剂和杀线虫剂。将其施入土壤后,残效期长达30—60天,具有触杀作用,能够杀死侵害植株的多种害虫。在谷物上无残毒及气味,对人畜毒性低,是当前防治害虫特别是水稻害虫的理想农药之一,国外已广泛应用。我省于1977年进口一批,由于一些地方使用不当,防效不理想,影响了推广。为此,我组于1979年进行了对水稻主要害虫的防效试验,现将初步结果,介绍如下。
Furadan (2,3-Dihydro-2,2-dimethyl-7-benzofuranyl carbamate) is a systemic insecticide and a nematicide. After its application to the soil, the residual effect of up to 30-60 days, with contact kill, can kill a variety of pests that affect plants. It is one of the ideal pesticides for controlling pests, especially rice pests. It has been widely used abroad. Our province imported a batch in 1977, due to improper use in some places, the control effect is not satisfactory, which has affected the promotion. For this reason, our group carried out the prevention and control test on major pests of rice in 1979, and the preliminary results are as follows.
