How to prevent and control brown rot in papaya cultivation?
1. Symptoms: Brown rot mainly damages the fruit, but can also damage flowers and young shoots. When the fruit is affected, small brownish, nearly circular spots appear first. As the disease progresses, the spots keep expanding. Under suitable conditions, the spots quickly spread over the entire fruit surface and gradually extend into the flesh. In severe cases, the entire fruit rots. After the diseased fruit loses water, it becomes a brown mummified fruit that hangs on the branch and does not fall for a long time. The pathogen on the pedicel or fruit infects the branches, forming brown canker spots, which affects the normal transport of nutrients and water, inhibits the growth and development of the branches, and causes the branches to die.
