摘要
霜霉病是冬瓜的主要真菌病害之一,在广东冬瓜产区危害时期主要是在夏秋季植株生长中后期和露水多、雾气重的季节。2003~2004年进行了新药剂25%阿米西达悬浮剂防治冬瓜霜霉病大田药效试验和使用技术研究,结果表明,25%阿米西达悬浮剂对冬瓜霜霉病具有优良的防治效果,且对冬瓜安全;施药3次后,25%阿米西达悬浮剂833倍的防治效果分别达到86.72%和84.35%,显著优于对比药剂58%雷多米尔-锰锌可湿性粉剂800倍的防效,达到快速、有效地控制冬瓜霜霉病和增产增收的目的,值得在生产上推广使用。
Downy mildew is one of the main diseases of wax gourd (Benincasa hispdia). The disease mainly occurrs at mid - late phase of plants growth, when the weather is dewy and foggy. 25% Amistar SC is a new fungicide which shows specifically high activity against wax gourd downy mildew. During 2003 to 2004, the result of tests in fields showed that 25 % Amistar SC using 1 : 833 for three times gave a control effect of 86.72% and 84.35% against wax gourd downy mildew. These results demonstrated that 25% Amistar SC had a better control effect against wax gourd downy mildew than 58% Ridoml WP(1:800), and it was worthy to be popularized on the growing practice.
