What term describes the presence of a pesticide on a treated substance after application?

1. Deposition

2. Exposure

3. Defoliation

4. Susceptibility

The correct answer is: Deposition

Deposition is the correct term that describes the presence of a pesticide on a treated substance after application. Deposition refers to the settling of pesticide particles onto surfaces in the environment. This term is commonly used when discussing the physical process of a pesticide coming into contact with a surface during application and remaining on that surface afterward. Exposure refers to when individuals or organisms come into contact with a pesticide, either through direct contact or by inhaling or ingesting it. Defoliation refers to the loss of leaves from a plant, typically caused by factors such as pests, diseases, or environmental stressors. Susceptibility refers to the likelihood of a pest or organism to be affected by a pesticide or other external factor.
