Abstract
Using five-point sampling method,we conducted an investigation on the occurrence and damage of tobacco( Yunyan No. 87) Alternaria alternate( Fr.) Keissler,as well as experiments for its control by fungicides in Baiwanyao town,Xingyi city,Guizhou province. The experimental results showed that tobacco Alternaria alternate occurred and endangered from middle-late July to the beginning of August,and spread faster under rainy weather. The average incidence of this disease in tobacco ripe and harvest period reached 30. 81%,and the average disease index was 10. 43. Spraying 400 ~ 800-times dilutions of 40% Dimethachlon had remarkable control effect on tobacco Alternaria alternate,and the control effect was 53. 12% ~ 64. 60%. Spraying 600-times dilution of 40% Dimethachlon could obtain the highest quality grade of baked tobacco leaves,14 percent higher mid-high-grade tobacco leaf proportion than the control,and 6786. 82 yuan / hm2higher comprehensive economic benefit than the control. But the concentration of sprayed fungicides had no significant influence on the yield of tobacco leaf.
