Illinois Field Crop Applicators Practice Test

What category of droplet measures between 250-350 microns and its abbreviation?

1. Coarse - C

2. Medium - C

3. Fine - C

4. Very Fine - C

The correct answer is: Medium - C

The category of droplets that measures between 250-350 microns is classified as "Coarse." This classification is based on the size of the droplets, which is crucial for understanding how they behave during application and how they interact with environmental factors such as wind and evaporation. Coarse droplets tend to settle more quickly and are less likely to drift, making them preferable in certain situations to minimize off-target application. The abbreviation used for coarse droplets is "C." Thus, when identifying droplet size categories, it is important to refer to established standards for effective pesticide application. In this context, understanding droplet sizes helps applicators make informed decisions regarding equipment setup and operational methods to achieve the desired coverage and efficacy while also adhering to safety regulations and environmental considerations.
