FL—8522为新研制的新型高效广谱内吸杀菌剂,用FL—8522 10、20、30、40、50ppm浓度进行黑穗醋栗白粉病室内孢子萌发试验,杀菌效果依次为92.46％、94.91％、97.92％、96.96％和87.75％,比三唑酮(粉锈宁)50ppm液杀菌效果27.70%相对提高233.79％、242.64％、253.50%、250.04％和216.79％;在哈尔滨、尚志县和海林县作田间小区药效试验,FL—8522 20、30、40、50ppm液平均防治效果依次为90.55％、92.27％、94.76％和94.85％,比三唑酮50ppm液的平均防治效果68.62％相对提高31.96%、34.47％、38.09％和38.23%。
FL-8522 is a new type of highly efficient broad-spectrum systemic fungicide. The indoor spore germination test of black currant powdery mildew was carried out with FL-8522 10, 20, 30, 40 and 50ppm at concentrations of 92.46%, 94.91 97.92%, 96.96% and 87.75%, respectively. The bactericidal effect of 50ppm liquid of triadimefon (triadimefon) was increased by 233.79%, 242.64%, 253.50%, 250.04% and 216.79% For field plot efficacy test, the average control effect of 20, 30, 40 and 50 ppm FL-8522 was 90.55%, 92.27%, 94.76% and 94.85%, respectively, which was 68.62% higher than that of triadimefon 50ppm. %, 34.47%, 38.09% and 38.23%.
