三种橡胶树乙烯利刺激剂对柑桔褐腐疫霉的毒力测定

Virulence Determine of 3 Irritants on Phytophthora citrophthora

通过含毒介质和橡胶叶片接种的试验方法,测定三种不同载体的乙烯利涂剂(含2％乙烯利)对柑桔褐腐疫霉的抑菌率,结果表明三种乙烯利涂剂均有不同程度的抑菌能力,其中抗病增胶灵抑菌能力最高,效能稳定,持效期长;而以淀粉和甲基纤维素为载体的涂剂抑菌能力较低,效能不稳定,持效期短。

It was determined that the effect of ethylene by 3 carrier on Phytophthora citrophthora by artificial inoculation. The result shows that all pastes have fungistasis with different degree. The bacteriostatic ability of 'Kangbing Zengjiaolin' is the highest, the efficiency is stable as well as for a long time. But the bacteriostatic ability of starch and methyl fibrin pastes are lower, the efficiency is not stable as well as for a long time.
