Virginia Commercial Pesticide Applicators CORE Exam

Which of the following is NOT a characteristic of weeds?

1. They produce seeds that can remain dormant.

2. They are typically cooperative with cultivated crops.

3. They can tolerate harsh environmental conditions.

4. They are often aggressive in growth.

The correct answer is: They are typically cooperative with cultivated crops.

The choice stating that weeds are typically cooperative with cultivated crops is accurate in identifying a characteristic that does not apply to weeds. Weeds are generally known for their competitive nature rather than cooperation. They compete with cultivated crops for essential resources such as nutrients, water, and light, often leading to reduced crop yields and disrupted growth patterns. In contrast, the other points illustrate common characteristics of weeds. Weeds can indeed produce seeds that remain dormant for extended periods, allowing them to survive adverse conditions until the environment is favorable for germination. They are resilient and can endure harsh environmental conditions, which contributes to their success as a persistent problem in agricultural and landscaped areas. Additionally, aggressive growth is a hallmark of many weed species, enabling them to outcompete and overwhelm desired plants. Understanding these traits of weeds is crucial for effective pest management strategies in agriculture and horticulture, emphasizing the need to recognize what constitutes a weed's nature and behavior.
