CDFA Pest Prevention Plant Regulation Practice Exam

Which of the following is NOT restricted by the nut tree pest quarantine?

1. Walnut trees

2. Pecan nuts

3. Pecan budwood

4. Pecan trees

The correct answer is: Pecan nuts

The reason pecan nuts are not restricted by the nut tree pest quarantine is that the quarantine typically focuses on live plant material that could harbor pests or diseases that threaten agricultural production. In contrast, processed or harvested products like pecans (the nuts themselves) do not pose the same type of risk for pest transmission. Therefore, they are generally exempt from such restrictions. On the other hand, items like walnut trees, pecan budwood, and pecan trees are all considered live material that could potentially carry pests and diseases harmful to agricultural health. As live plants or parts of plants, they can be vectors for the spread of pests, which is why they fall under the purview of pest quarantines.
