Management of Major Diseases of Cucumber 

Cucumber is one of the most popular vegetables consumed in raw form. It is a warm-season crop usually cultivated in both protected and open field conditions. It is widely cultivated in the southern part of India. The crop growth and development have been hindered by several Pathogens. In this blog let us understand the strategies for managing major Diseases of the cucumber. 

Damping off 

Damping off in cucumber is caused by a soil-borne fungus called Pythium. There are two types of damping off in cucumber pre-emergent and post-emergent. In the pre-emergence, the seedlings are killed just before they reach the soil surface and in the post-emergence phase, water-soaked depression near the collar regions above the soil can be noticed. Which in later stages leads to the collapsing or wilting of seedlings in portray.
