CDFA Pest Prevention Plant Regulation Practice Exam

What type of organism is primarily targeted by regulations concerning Copper's broomrape?

1. Parasite

2. Fungus

3. Bacteria

4. Virus

The correct answer is: Parasite

Copper's broomrape, known scientifically as Orobanche cupularis, is primarily classified as a parasite. This organism specifically invades and feeds on the roots of other plants, deriving nutrients from its host without contributing any beneficial use in return. The regulations surrounding Copper's broomrape focus on its impact on agriculture and ecosystems, as it can severely affect crop yield and health. Parasites are organisms that depend on a host for survival, and in the case of Copper's broomrape, the plant's hosts often include various crops, which makes this regulation particularly important for agricultural management. The other options, while representing different categories of organisms, do not accurately reflect the nature of Copper's broomrape. Fungus, bacteria, and viruses each have distinct modes of action and implications in pest prevention and are not the focus of regulations concerning this specific plant parasite.
