CDFA Pest Prevention Plant Regulation Practice Exam

The peach wart area under quarantine includes which of the following?

1. all states and districts in the US

2. Arizona, New Mexico, Texas, and Utah

3. Idaho, Oregon, and Washington

4. All states east of and including New Mexico, Colorado, Wyoming, and Montana

The correct answer is: Idaho, Oregon, and Washington

The correct choice identifies specific states that are commonly associated with the peach wart pest, which is a serious concern in peach cultivation. Peach wart, caused by the fungus Taphrina deformans, can lead to significant damage to peach trees. Under regulations aimed at controlling the spread of this pest, certain areas may be quarantined to prevent its movement to unaffected regions. The quarantine typically includes states where peach wart has been found or states that are at a higher risk due to climatic or agricultural conditions conducive to the pest's survival and reproduction. States such as Idaho, Oregon, and Washington have historically been included in discussions around peach wart due to their production of stone fruits or their geographical proximity to affected areas. This targeted approach ensures that efforts to contain or manage peach wart are effective, protecting peach crops in regions that are not yet infested. The other options either overgeneralize the areas included in the quarantine or identify regions that are not aligned with the known distribution of peach wart. This indicates a lack of understanding about the specific ecological and agricultural impact of the pest in different states.
