百菌清烟剂的研制及应用

The Chlorothalonil Smoke Agent Used in Greenhouse

报道了适合温室用百菌清烟剂的研制和应用。经筛选。确定百菌清烟剂以百菌清和硫磺为主剂．其含量分别为１０％和５％。制定了测定烟剂自燃温度、成烟率、热贮分解和防潮性能的方法。通过测定、百菌清烟剂的自燃温度为１６２．７℃：成烟率８２．０３％；热贮分解率７．７％；吸潮率（３４±０．５）℃．１４ｄ）２．５３％。经田间小区试验证明．该烟剂对黄瓜双霉病的防治效果在９０％以上；对黄瓜炭疽病的防治效果在７０％以上：对黄瓜黑星病的防治效果在４０％以上。与对照相比增产１５％以上。

The smoke agent of 10% chlorothalonil and 5% sulphur was determined. The self-burned temperature, the rate of smoking, the resolved rate in hot stored condition and the moisture-proofed ability of smoke agent were also determined. through which the authors got best prescription. The prescription is as follows: the self-burned temperature 162. 7℃. the rate of smoking 82. 03%, the resolved rate in hot stored condition 7. 72%. the water-absorbed rate 2. 53% (under the condition of (34 ± 0. 5)℃ . 14 d). The effect of the smoke agent is as follows: Plasmopara spp. more than 90%. Colletotrichum spp. more than 70%, Fusicladium spp. more than 40%.
