【摘要】 敌锈纳和胶体硫按重量1:2配成混合剂,在高温(35℃)、低温(4～5℃)、室温(广州地区室内温度,冬季一般为8～10℃,夏季30～32°)三种条件下贮藏。经670天贮存后测定其中敌锈钠的含量,与现配混合剂比较,没有显著差异;用花生和豆角锈病的防治效果来检测,也没有显著差异。贮藏后混合剂中的胶体硫的稳定性亦通过对花生叶斑病、葫芦瓜白粉病、豆角赤斑病和绿豆叶斑病的防病效果加以检验,结果与现配混合剂或等量的单纯胶体硫的药效均无显著差异。更多还原

【Abstract】 A mixture of sodium sulfanilate and colloidal sulfure was prepared with a proportion of 1 : 2 by weight and was stored under three different temperatures, 35℃, 4 - 5 ℃ and room temperatures in Guangzhou ranging from 8-10℃ in winter seasons to 30-32℃ in summer seasons. Test were made of the stability of the two components of the mixture against temperature effects in the course of storage for about 2 years with either chemical analysis or disease control efficacy tests of each of the compounds. No significant reliction was denonstrated in the anoint of solium sulfanilate in the mixture as compared with that in a freshly prepared mixture and no significant changes in control efficicy of pernut rast and aspsragus long bean rust. The control efficacy of sulfur; in the mixiure was tested with peanut leaf spot, green bean leaf spot, asparagus long bean Cercorspora leaf spot, and gourd powdery mildew and no significant changes was observed in all cases as conpired with that either in the freshly prepared mixture or of sulfure alone.更多还原
