TEST ON DIATOMACEOUS EARTH PROTECT-IT^(TM) TO CONTROL STORED-GRAIN INSECTS

在实验室内用 5 0 0mg/kg的Protect -ItTM 处理小麦 ,几乎可以杀灭所有试虫的成虫 ,与 80mg/kg杀螟松处理效果相似 ,并能有效抑制赤拟谷盗的发展 ,对玉米象和谷蠹也有一定的抑制作用。从实仓试验结果来看 ,其在稻谷中使用效果优于小麦 ,同时实仓的生物测试结果表明Protect -ItTM有很好的持效作用。

mg/kg diatomaceous earth protect-it TM was used to control stored-grain insects in wheat in the lab.The results showed that it can kill all the tested adult insects,it has the same effect as 8mg/kg FEN.The Tribolium Castaneum (H.) were well controlled,and it can also control Rhyzopertha dominica (F.)and Sitophilus zeamais (M.).The results in model bin showed that the effect of diatomaceous earth protect-it TM in paddy was better than in wheat,and the effect can last a long time.
