CDFA Pest Prevention Plant Regulation Practice Exam

Which of the following is NOT covered under the peach mosaic interior regulation?

1. Almond trees

2. Peach trees

3. Peach pits

4. Prune trees

The correct answer is: Peach pits

The peach mosaic interior regulation primarily focuses on specific host plants that can carry or transmit the peach mosaic virus, which causes significant damage to peach crops. The correct response indicates peach pits fall outside the regulation's coverage. Peach pits are the seeds of the peach fruit and, while they are related to the peach tree, they are not living plants subject to direct regulation regarding pest prevention. Instead, the regulation is concerned with whole trees and susceptible plant matter that can harbor or spread the virus. In contrast, the other options include live plant species (almond trees, peach trees, and prune trees) that can directly influence the ecology and spread of the peach mosaic virus. These trees are included in the regulation since they can be carriers of the disease or at risk of infection themselves. Understanding the scope of regulations like this is essential because it helps ensure that the management practices are focused on living hosts that could perpetuate pest issues versus inert plant parts like seeds, which do not pose the same level of risk.
