在近几年的细菌病害调查中,发现番茄上有四种细菌病害即:危害锥管束系统的番茄溃疡病,危害叶片和果实的疮痂病及引起果实腐烂的软腐病及果腐病。这几种病害在局部地区及个别年份危害很大,在症状上不易区别。由于引起这几种病害的病原细菌不同,因此在防治上所采用的方法也就不一样。所以正确识别这几种病害对防治是非常必要的。下面就简要介绍一下这几种病害的症状、区别及防治方法。
In bacterial disease surveys in recent years, there have been four bacterial diseases found in tomatoes, namely, tomato canker disease that harms the system of pyramidal tubes, scabs that endanger leaves and fruits, and soft rot and fruit rot that cause fruit decay. These diseases are very harmful in some areas and individual years and are not easy to be distinguished in symptoms. Due to the different pathogenic bacteria that cause these diseases, the methods used in prevention and treatment are not the same. Therefore, proper identification of these diseases is very necessary for prevention and treatment. Here is a brief introduction to the symptoms of these diseases, differences and prevention methods.
