番茄早疫病是我县番茄主要病害之一,中后期常伴有晚疫病同时发生。由于进入7月份我县雨季与番茄开花、座果生育同期进行,每年番茄早疫病都发生较重。1986、1987年7月份连阴雨天气较多,造成番茄早疫病严重发生,刚开始采摘上市就毁于早疫病,叶枯果烂,一般很少收成,多数绝收。此病已成为我县番茄生产的一大障碍。 Tomato early blight is one of the main diseases of tomato in our county, late blight often accompanied by late blight occur simultaneously. Due to enter the July rainy season in my county and tomato flowering, fruit bearing the same period of birth, tomato early blight every year have occurred heavier. In 1986 and July 1987, there was even more rainy days, resulting in serious occurrence of early blight of tomato. At the beginning of picking and listing, it was destroyed by early blight and withered leaves and rotten leaves, with seldom crops and most of them harvested. The disease has become a major obstacle to the production of tomatoes in our county.
