在病虫害的化学防治中,改进药剂剂型,可以达到经济、合理施用;防止污染,保护天敌;节约劳力、保证安全。 北京农业大学植物保护系,中国农业科学院棉花研究所于1980年冬天开始与美国FMC公司协作,对呋喃丹液剂35ST与多菌灵(MBC)复配种衣剂进行了研究,80年冬做了室内药剂配比试验,81、82两年进入田间试验,获得了兼防棉苗病害(包括立枯、炭疽及苗期枯萎)及棉蚜的良好效果。最近,经河南、河北、山东、湖北、上海、北京各试点总结,一致认为是有前途的。
In the chemical control of pests and diseases, the improvement of pharmaceutical dosage forms can achieve economical and reasonable application; prevent pollution and protect natural enemies; save labor and ensure safety. Plant Protection Department of Beijing Agricultural University, Chinese Academy of Agricultural Sciences Institute of Cotton in the winter of 1980 and the United States began collaboration with the FMC company, the carbofuran liquid 35ST and carbendazim (MBC) with the study of seed coating, made 80 years of winter 81%, 82%). Two years into the field trials 81,82 years, won the good effect of both cotton seedling disease prevention and treatment (including Withered, anthrax and seedling wilt) and cotton aphid good results. Recently, the pilot concluded by Henan, Hebei, Shandong, Hubei, Shanghai and Beijing agreed that there is a promising future.
