Wyoming Pesticide Applicator Certification Practice Test

What is a winter annual plant?

1. An adjuvant used to reduce liquid surface tension

2. A plant that completes its life cycle within a year

3. A device with multiple spray nozzles

4. A pesticide application device attached to a vehicle

The correct answer is: A plant that completes its life cycle within a year

A. This option describes a chemical used in agriculture, not a plant. C. This option describes a mechanical device, not a plant. D. This option describes a device used in agriculture, not a plant. A winter annual plant is a specific type of plant that goes through its complete life cycle, from seed to maturity and back to seed, within a period of one year. This means that the plant germinates, grows, flowers, produces seeds, and dies all within a span of a single year. Therefore, this option (B) is the correct answer. The other options (A, C, D) do not accurately describe a winter annual plant. Option A describes an adjuvant, which is a substance used to enhance the effectiveness or stability of another substance. Option C describes a device that sprays liquid, which is not related to a plant's life cycle. Option D describes a device that helps with the application of pesticides, not the attributes of a plant.
