CDFA Pest Prevention Plant Regulation Practice Exam

Which type of citrus is affected by the federal Domestic quarantine #83?

1. Foreign grown limes

2. Spanish lemons

3. Japanese grown Unshu oranges

4. Mexican grapefruits

The correct answer is: Japanese grown Unshu oranges

The correct answer pertains to the specific types of citrus fruits that are subject to federal Domestic Quarantine #83, which is primarily aimed at preventing the spread of specific pests and diseases that can threaten citrus crops in the United States. This quarantine addresses concerns related to pests such as the Asian citrus psyllid and other diseases like Huanglongbing (HLB), commonly known as citrus greening disease. Japanese grown Unshu oranges are significant in this context because they are included in the regulations outlined by the quarantine. The quarantine measures are designed to restrict the importation of certain citrus varieties from regions where these pests and diseases are prevalent, directly impacting international trade and domestic agricultural health. While the other options may be types of citrus or fruit, they are not specifically included in the scope of the federal Domestic Quarantine #83, making the Unshu orange the correct answer concerning the regulations and their objectives. Understanding these regulations is essential for anyone engaged in the pest prevention and plant regulation field, as they aim to protect U.S. citrus production and market stability.
