CDFA Pest Prevention Plant Regulation Practice Exam

Peach wart disease typically produces symptoms primarily in the:

1. fruits

2. roots

3. leaves

4. blossoms

The correct answer is: fruits

Peach wart disease is a fungal infection caused by the pathogen Taphrina deformans, and it predominantly affects the fruit of the peach tree. The symptoms of this disease manifest as warty growths or deformities on the fruit surface, which can lead to premature fruit drop and affect the overall yield and quality of the crop. While the disease may impact other parts of the tree, such as leaves and shoots, the most conspicuous symptoms are clearly visible on the fruits. This is significant because fruit quality is a crucial factor in commercial peach production, making the impact on the fruit the most important aspect to address for growers facing this disease. In contrast, symptoms on roots, leaves, or blossoms, although they may occur in some instances, are not the primary concern when it comes to peach wart disease. The fruit is therefore the area of focus for identifying and managing this particular pest issue.
