Which one of the following states is NOT under quarantine for cedar-apple rust?

1. A. Oklahoma

2. B. Wyoming

3. C. Alaska

4. D. New York

The correct answer is: B. Wyoming

Cedar-apple rust is a fungal disease that affects apple and cedar trees and is more commonly found in certain regions. Quarantine measures are typically implemented in areas where a pest or disease poses a significant threat to agricultural interests or natural resources. The correct answer indicates that Wyoming is not under quarantine for cedar-apple rust. This is likely due to the state's environmental conditions, which may not support the lifecycle of the disease as actively as other states. For instance, states like Oklahoma and New York may have established quarantine protocols in place due to higher prevalence of the disease or conditions favorable for its spread. Alaska, having a different climate, typically does not harbor these kinds of agricultural threats, impacting the spread of diseases as well. Understanding the distribution and life cycle of cedar-apple rust can help in identifying areas that require quarantine and those that do not. By noting which states are quarantined, you can appreciate how local agriculture might be affected or safeguarded from such diseases.
