棉花播种前用药剂进行种子处理是目前防治苗期根病最常用的方法。过去生产上使用的拌种药剂西力生和赛力散等,均以汞为原料,残留毒性大,对人畜有危害,今后不再提倡使用。为了进一步寻找高效低毒的代汞拌种剂,今年沈阳化工研究院和南开大学元素有机研究所提供了一些药剂新样品,与我所驻安阳白壁公社基点组和大寒、郭盆大队科研组协作,对十一种杀菌剂进行了小区试验和大田示范。现将试验示范结果简介如下:
Seed treatment with cotton seed before treatment is currently the most commonly used method of prevention and treatment of seedling root disease. In the past, the seed dressing agents used in production, such as Xili Lixue and Saoli Bulk, all use mercury as raw material, with great residue toxicity and harm to human beings and animals, and will not be promoted in the future. In order to further find efficient and low toxic generation mercury dressing seed, Shenyang Institute of Chemical Industry and Nankai University Institute of Elemental Organic Chemistry this year to provide some new samples of pharmaceuticals, and I am in Anyang Baibing Commune base point group and the Great Cold, Guo Basin brigade research group collaboration , 11 kinds of fungicides were plot test and Daejeon demonstration. Now the pilot demonstration results are as follows:
