水稻细菌性条斑病是国内植物检疫对象。近年来,该病已上升为中南地区水稻的主要病害。其对产量的影响较大,一般减产10～20%,严重影响了中南地区水稻生产的发展。1986年～1988年,我们利用TCCA(三氯异氰脲酸”、又名“强氯精”)进行了病种处理试验,取得了良好的防治效果。一、材料与方法1.药剂消毒效果测试1986年我们进行了室内病种消毒效果试验。供试药剂为85%TCCA(南宁化工厂)可湿性粉剂。试验设10个处理,分别为水+TCCA500倍(水浸12小时,再用TCCA500倍
Rice bacterial leaf streak is the object of domestic phytosanitary. In recent years, the disease has risen to the major diseases of rice in Central South China. Its impact on the yield is larger, the general reduction of 10 to 20%, seriously affected the development of rice production in central and southern regions. From 1986 to 1988, we used TCCA (trichloroisocyanuric acid), also known as “strong chlorine fine”) to carry out the disease treatment test and achieved good prevention and cure effect.Materials and Methods 1. Pharmacy disinfection effect Test In 1986, we conducted indoor disinfectant test for 85% TCCA (Nanning Chemical Factory) wettable powder.We set up 10 treatments, which were 500 times of water + TCCA (immersion for 12 hours, reuse of TCCA500 Times
