地瓜茎线虫病是地瓜生产上的一种毁灭性病害,其病原线虫是一种抗药性很强的内寄生线虫,近年来,虽利用农业措施在防治上取得显著效果,但在化学防治方面却一直未找到较理想的药剂。1979年以来,我们先后用辛硫磷、混杀磷、三唑磷、呋喃丹、涕灭威、易卫杀等十三种农药及农抗23—16等进行多次室内外药效测定,证明三唑磷防病效果高而稳定,使用方便,对作物无药害,可做大面积示范推广,易卫杀防病效果稳定性差些,需做进一步试验。现将试验结果摘要如下:
Sweet potato stem nematode disease is a devastating disease in the production of sweet potato, and its pathogenic nematode is a highly resistant endoparasitic nematode. In recent years, though agricultural measures have been used to achieve significant results in prevention and treatment, Has not found the ideal agent. Since 1979, we have conducted many indoor and outdoor pharmacodynamic tests with 13 pesticides such as phoxim, triazophos, triazophos, carbofuran, aldicarb, Prove triazophos disease prevention and control of high and stable, easy to use, no phytotoxicity on crops, can do a large area demonstration and promotion, easy to kill and disease prevention and control stability is poor, need to be further tested. The test results are summarized as follows:
