枯萎病是一种由土壤传播、根颈部侵入的系统性病害,又称萎蔫病,是黄瓜上的重要病害,重茬棚室黄瓜一般病株率在10%～30%,重病棚室达50%以上,绝大多数感病株在开花结果期陆续萎蔫枯死,产量损失较大。为了寻求防治黄瓜枯萎病的理想药剂,探讨其防治技术,有效控制黄瓜枯萎病的危害,2006～2007年,我们进行了80%福美双·甲基硫菌灵WP防治黄瓜枯萎病的田间药效试验,已取得初步结果,现报告如下。
Fusarium wilt is a systematic disease transmitted by soil and invading root and neck. It is also called wilt disease. It is an important disease on cucumber. The rate of common diseased plants in cucumbers is 10% ~ 30% % Or more, the vast majority of susceptible strains wilt one after another in the flowering period, yield loss greater. In order to seek the ideal agent for controlling cucumber wilt, explore its control technology and effectively control the cucumber wilt disease. From 2006 to 2007, we conducted 80% thiotepa thiophanate-methyl WP control field cucumber wilt disease efficacy Trial, preliminary results have been achieved, the report is as follows.
