大豆种衣剂防治根腐病方法研究初报

在防治大豆根腐病的研究中，通过种子处理防治大豆根腐病的研究，应是一个主要内容，但首先遇到的问题有二；一是有效的药物（或药剂型），二是能使大豆种子上带有足够的药量的方法。本文主要介绍通过农药的筛选、复配、在确定有效药剂配方的前提下，结合防治方法的研究，经过多年室内外试验，示范，研制成功了具有促进大豆生长发育，增另大豆根瘤量，防治大豆根腐病效果达８５％，增产１５％左右的“大豆微复药肥Ｉ号”种衣剂。

PRELIMINARY REPORT OF SEED-COATING CONTROL METHOD OF SOYBEAN ROOT ROT

Seed treatment is and important measure to control root rot of soybean,but there were two problems: the first one was to have effective fungcide(or type);the second was how to keep sufficient dosage on soybean seeds.Mineralfungicide mixture No.1 was developed for soybean seedcoating after screeming of fungicid and comprehensive experiments in laboratory and fields, and several year's demonstration.The effect of minerals and fungicide mixture No. 1 on control of soybean root rot was over 80%, increased yield 15%; meanwhile it could promote soybean growth and development,and increased nodule number.
