据笔者近日参加农业部药检所2003年“中国农药管理与市场营销战略暨农药信息工作会议”获悉,农业部药检所有关领导在大会上透露:菊酯类农药可望在水稻害虫防治上开放使用。在二十世纪八十年代,由于菊酯类农药对水生生物毒性高,易引起稻飞虱再猖獗且无较好的防治农药品种等原因,有关部门作出了禁止在水稻上使用菊酯类农药的决定。但经过近二十年的发展,出现了一些新的情况:一是菊酯类农药得到了长足的发展,出现了一些对水生生物安全的新品种;二是目前防治水稻稻飞虱的再猖獗已有较好的农药品种,如吡虫啉、扑虱灵等;三是在甲胺磷等高毒农药淘汰后,防治水稻螟虫没有理想的药 According to the author recently participated in the 2003 Ministry of Agriculture Drug Administration “China Pesticide Management and Marketing Strategy and Pesticide Information Conference ” was informed that the leaders of the Ministry of Agriculture drug inspection revealed at the meeting: pyrethroid pesticides are expected in the prevention and control of rice pests Open to use. In the 1980s, due to the high toxicity of pyrethroid pesticides to aquatic organisms and their susceptibility to the re-emergence of planthoppers and their lack of good control over the varieties of pesticides, the authorities concerned have banned the use of pyrethroid pesticides on rice decision. However, after nearly two decades of development, some new situations have emerged: first, the development of pyrethroid pesticides has made considerable progress, some new varieties of aquatic organisms have emerged, and second, the current rampant prevention and control of rice planthoppers There are better varieties of pesticides, such as imidacloprid, buprofezin and so on; Third, after the elimination of methamidophos and other highly toxic pesticides, there is no ideal medicine to control rice stem borers
