Virginia Commercial Pesticide Applicators CORE Exam

What is one significant advantage of using dust formulations in pesticide application?

1. High cost per unit of active ingredient

2. Requires extensive measurement

3. Usually ready to use

4. Uniform application

The correct answer is: Usually ready to use

The option "usually ready to use" highlights a significant advantage of dust formulations in pesticide application. Dust formulations are typically pre-mixed and do not require further dilution or preparation before application. This ease of use allows applicators to quickly and efficiently apply the pesticide without the need for additional steps, which can save time and reduce the potential for measurement errors that could occur if the product needed to be mixed. The other aspects mentioned, such as high cost per unit of active ingredient and the need for extensive measurement, point to disadvantages or additional concerns related to the use of pesticides in general but do not reflect a key benefit of dust formulations. Uniform application is certainly important as well, but it does not specifically relate to the immediate usability of dust formulations, which is primarily what sets them apart regarding convenience and ease of application.
