甲胺磷是一种高效、广谱的有机磷杀虫剂。但由于该药毒性较高,剂型单一,长期施用后害虫易产生抗性,必将影响甲胺磷的发展。为了降低其毒性,延缓抗性,降低农本,发展我国新的农药制剂,我们于1980年开始进行了甲胺磷与敌百虫混合乳剂(以下简称甲敌混剂)的配方与药效研究。现将三年来的室内及田间药效试验结果整理如下。 Methamidophos is an efficient, broad-spectrum organophosphate insecticide. However, due to the high toxicity of the drug and the single dosage form, the pest susceptible to long-term application will surely affect the development of methamidophos. In order to reduce its toxicity, delay the resistance, reduce the cost of agriculture and develop new pesticide formulations in China, we started the formulation and efficacy studies of methamidophos and trichlorfon mixed emulsions (hereinafter referred to as “enemies”) in 1980 . Now three years of indoor and field efficacy test results are summarized below.
