Tomato leaves were inoculated with 1×104conidia·mL-1 and placed in a dew chamber for 0 to 18hrs at 10 to 25C. Eighteen days after inoculation, leaf mold incidence appeared in 9hr treatment of leaf wet duration and the proper temperature was 15 to 20C. In 10 and 25C treatments, the incidence rate was 0% and 4.2%, respectively. The most important factors regard to leaf mold incidence were leaf wet duration and temperature. Considering the proper tomato growth temperature is 15-25C, control by leaf wet duration is easier than control by temperature to prevent leaf mold incidence. After leaf mold inoculation, incidence appeared at 20 days and the latency period was estimated as 14-15 days. The leaf mold incidence rate was the highest at 15C and 20C. When 'trihumin' (triflumizole 30%) was applied at 12 hr of leaf wet duration, the control effect was the highest at 90% up to 168 hr but after 240 hr, it dropped to 60%. When 'Demani B' (polyoxin B 50%) was applied at 12 hour of leaf wet duration, the control effect was the highest at 91% up to 144hr but after 240hr, it dropped to 58%, similar to trihumin application treatment. When 'belqute' (Iminoctadine tris 40%) was applied at 12 hours of leaf wet duration, the control effect was the highest at 93% up to 144 hr but after 240 hr, it dropped to 65%.

番茄叶霉病发病率预测及农药喷洒计划研究

用1×104分生孢子·mL-1接种番茄叶，并在10至25℃下于露室中放置0至18小时。接种后18天，在9小时的叶片湿润时间处理中出现了霉菌发生，合适的温度为15至20℃。在10和25C处理中，发生率分别为0％和4.2％。关于叶片霉菌发生率的最重要因素是叶片湿润持续时间和温度。考虑到适当的番茄生长温度为15-25℃，通过叶片湿润时间控制比通过温度控制更容易以防止叶片发霉。叶霉菌接种后，发病发生在20天，潜伏期估计为14-15天。叶霉菌发生率在15℃和20℃时最高。当在叶片湿润时间的12小时使用'trihumin'（triflumizole 30％）时，控制效果在168小时内达到90％的最高值，但在240小时后降至60％。当在叶片湿润时间的12小时内施用'Demani B'（多毒素B 50％）时，在144小时之前，其防治效果最高，为91％，但在240小时后，其防治效果下降至58％，类似于三胡敏施用处理。当在叶片湿润时间的12小时使用'belqute'（次明三醇40％）时，在144 hr之前，其防治效果最高，为93％，但在240 hr后，防治效果降至65％。
