CDFA Pest Prevention Plant Regulation Practice Exam

Where is the golden nematode of potatoes known to occur in the US?

1. In portions of New York State

2. Throughout the Midwest

3. In Idaho and California

4. In the southern states

The correct answer is: In portions of New York State

The golden nematode of potatoes, scientifically known as Globodera rostochiensis, is primarily found in specific regions where conditions are suitable for its life cycle and potato cultivation is prevalent. In the United States, this pest has been reported mainly in portions of New York State, particularly in areas with significant potato farming activities. Management and agricultural practices in New York have also been heavily influenced by its presence, leading to stringent regulations and pest control measures. While the other options mention various regions across the United States, they do not reflect the known occurrence of the golden nematode. For example, while some pests might be widespread in the Midwest or other states, the golden nematode has not been confirmed in those areas. The specificity of the golden nematode's location in New York is a critical aspect of its study and management, making this choice the accurate one regarding its known distribution in the U.S.
