1985～1986年我们用40种杀菌剂对泽蛙蝌蚪进行了毒性测定,发现不同的杀菌剂对蝌蚪的毒性不同。毒性大的有百菌清、菲醌、苏化911;毒性较大的有克瘟散、敌菌灵;毒性低或较低的有代森铵、瑞毒霉、异稻瘟净、富士一号、稻瘟净、三环唑、多菌灵、甲基托布津等。石灰超量使用,对蝌蚪杀伤力极大。同一种杀菌剂,不同的加工剂型对蝌蚪的毒性不同,以乳油的毒性最大,颗粒剂则较小,蝌蚪群体异质性小,对杀菌剂的毒性反应敏感,用药量要求严格。 From 1985 to 1986, we used 40 fungicides to determine the toxicity of tadpoles of frogs, and found that different fungicides have different toxicity to tadpoles. Chlorothalonil, phenanthrenequinone and thugenization 911 were found to be highly toxic. In the more toxic cases, No., rice blast net, tricyclazole, carbendazim, thiophanate-methyl and so on. Excessive use of lime, lethal to tadpoles. The same fungicide, different processing formulations of tadpoles of different toxicity to the greatest toxicity of EC, smaller granules, tadpoles heterogeneity group is small, sensitive to the toxicity of disinfectants, the dosage of strict requirements.
