于1973—1977年,先后用省内、外7个菌株,或菌粉成品(菌株扩大培养后再行试验)进行了试验。试验结果,(一)菌株来沅不同对害虫的效果也不同,如对茶毛虫,以广东林科所18号菌株见效快,9天后防效达90%以上,福建林科所亭下菌株次之,9—15天达80%以上;茶丽纹象甲,以浙农大208号菌株较好,防效65—78%,(二)使用方法不同,效果也不

In 1973-1977, seven kinds of strains in the province and abroad were successively used, or the finished product of bacterial powder (the strain was expanded and tested again). The results of the experiment (1) The effect of different strains on the pests was also different. For instance, the activity of the tea caterpillar on the 18th strain of Guangdong Linke was quick, and the control effect reached 90% after 9 days. , 9-15 days of more than 80%; tea reticulata, to Zhejiang Nong 208 strains better, control efficiency 65-78%, (b) the use of different methods, the effect is not
