Certainly, here is an article on Wilt attack on custard apple:
Custard apple, also known as sugar apple or sharifa, is a tropical fruit that is prized for its deliciously sweet and creamy flesh. Unfortunately, custard apple trees are susceptible to a disease called Wilt, which can cause significant damage to the tree and reduce fruit production.
Wilt is caused by a soil-borne fungus called Phytophthora nicotianae, which attacks the roots of custard apple trees. The fungus can also infect the trunk and branches, causing the tree to wilt and die. In addition to being a major concern for custard apple growers, Wilt can also affect other fruit trees and ornamental plants.
The first sign of Wilt in custard apple trees is a yellowing or wilting of the leaves, which may eventually turn brown and fall off. The tree may also show signs of stunted growth and a general decline in health. As the disease progresses, the tree may develop cankers on the trunk and branches, and the bark may become cracked and discolored.
Preventing Wilt in custard apple trees requires a combination of cultural practices and fungicide treatments. For example, custard apple trees should be planted in well-draining soils and irrigated with clean water. It is also important to avoid planting other diseased trees in close proximity to custard apple trees, as this can increase the risk of infection.
Fungicide treatments can also be effective in preventing Wilt in custard apple trees. Fungicides containing metalaxyl or phosphorus acid have been shown to be effective against Phytophthora nicotianae. However, it is important to follow the label instructions carefully and use fungicides only as directed.
In summary, Wilt is a serious disease that can affect custard apple trees and other plants. Preventing Wilt requires a combination of cultural practices and fungicide treatments. If you suspect that your custard apple tree may be infected with Wilt, it is important to take swift action to prevent the spread of the disease and preserve the health of your tree.
