Papaya Tree Diseases
Papaya tree suffer from a number of diseases which may severely weaken the health of a papaya tree. For individual planted papaya trees, the impact of a papaya disease will be easily controlled. However, for some commercially planted papaya orchids, one disease will affect thousands of trees which may seriously endanger the survival of these trees. Generally, the denser the trees are planted, the easier they are affected by papaya diseases. This document will introduce some common diseases existing on papaya trees.
Papaya ringspot is mainly caused by the ringspot virus which is easily transmitted thorough insects. The symptom of the disease will cause unhealthy leaves. Also it will produce some ring spot on papaya fruits as well. In severe case, trees will die very quickly. Currently there are no effective remedies for this disease. People are advised to get rid of the infected leaves and branches quickly to prevent the spread of the disease. Regularly pruning is necessary to lower the chance of cross infection to other papaya trees.
Phytophthora collar rot will infect the parts of the trees in the soil, mainly the tree roots and some part of the trunk. It will cause the roots to rot and result in the demise of the tree. This disease will cause the leaves to drop quickly and severely weaken the health of the tree. This disease is caused by fungi, and some fungicide can be applied as a disease controlling method. Another way to decrease the possibility of this disease is to improve the drainage ability of the soil. You should apply fungicide as early as possible to prevent the disease from spreading into the whole orchard.
Fruit anthracnose is a disease which will infect the ripening fruits in harvesting season. It will produce spots on the surface of the papaya fruits. The size of the spots will expand during the ripening process. To prevent the happening of this disease, you should pick up the ripened fruits as quickly as possible. Do not leave ripened fruits on the branches for a long time. Some hygiene actions can also decrease the possibility of getting infected.
