Commodity Fumigation License Practice Exam

What is one method of application for soil fumigants?

1. Broadcasting

2. Drenching

3. Injecting

4. Both A and C

The correct answer is: Both A and C

The method of application for soil fumigants is indeed both broadcasting and injecting. Broadcasting involves spreading the fumigant evenly across the soil surface, allowing it to volatilize and penetrate the soil. This method is effective for treating large areas and ensuring an even distribution of the fumigant throughout the topsoil layer. Injecting, on the other hand, involves applying the fumigant directly into the soil using specialized equipment. This method allows for deeper penetration of the fumigant, targeting specific layers of the soil and maximizing the effectiveness of the treatment against pests or diseases present in the root zone. Choosing both broadcasting and injecting recognizes that different situations may call for different application methods. Each technique has its advantages depending on the type of soil, the target pest, and the specific conditions of the area being treated. Therefore, acknowledging both methods as valid application techniques comprehensively covers the range of practices used in soil fumigation.
