Iowa Pesticide Applicator Practice Exam

Which application method involves gravity to drop granules below the feed-gate opening?

1. Band application

2. Drop application

3. Broadcast application

4. Directed application

The correct answer is: Drop application

The method that involves gravity to drop granules below the feed-gate opening is commonly referred to as drop application. This technique allows for granules, such as fertilizers or pesticides, to be released directly onto the target area, leveraging gravity to facilitate the precise dropping of material. This method is beneficial for ensuring that the application is localized to the intended area, which can enhance efficacy and reduce waste. Utilizing gravity in this method also allows for a controlled distribution, minimizing the chance of drift and ensuring that the product reaches the ground as intended. This is particularly useful in situations where other methods might lead to uneven distribution or require more complex equipment setups. The simplistically effective nature of drop application makes it a preferred choice for many applicators who want to ensure maximum application accuracy while using granular products.
