Abstract

The invention provides primer composition used for specifically detecting cladosporium cucumerinum and/or fusarium oxysporum and mycosphaerella melonis in sample and a PCR assay kit containing the primer composition. The invention also provide a method for detecting cladosporium cucumerinum and/or fusarium oxysporum and mycosphaerella melonis in sample. The method of the invention not only can rapidly, simply and accurately detect disease, and detection cost can be greatly saved.

Description

technical field [0001] The present application relates to the field of biotechnology, especially the field of biological detection. Specifically, the application relates to a detection kit and a detection method for Melon scab bacteria. Background technique [0002] Melon scab (Cladosporium cucumerinum, also known as melon scab) can cause cucumber, watermelon, zucchini, pumpkin, muskmelon, winter melon and other melon diseases, and scab on cucumber is the most common [1]. Melon scab is a devastating disease on melons. Due to its serious damage and difficult control, it has been listed as a national plant quarantine pest in my country. Fusarium oxysporum and Didymelabryoniae (Mycosphaerella meloni in domestic reports) are also important pathogens of melons. These three pathogens are very common in melons. [0003] Cucumber scab can be infected at the seedling stage and adult plant stage. The pathogenic bacteria can infect young leaves, tender stems and young melons. It is a...
