Which statement about granular applicators is true?

• A. Ground speed has no effect if the application rate.
• B. In a rotary spreader, lighter granules are thrown further than heavier ones.
• C. Drop spreaders are superior to rotary when more precise placement of the pesticide is desired.
• D. Granular spreaders are always less accurate than liquid applications.

Answer: (C)

Granular applicators differ in how they place material on the ground. Drop spreaders release granules straight down, creating a narrow, well-defined band of coverage right where you want it. Rotary spreaders fling granules outward with a spinning disc, producing a wider pattern that is more affected by wind, ground speed, and the weight and shape of the granules. Because of this, drop spreaders provide more precise placement, which is essential when treating close to edges, structures, or small areas. Ground speed does influence how much area a given amount of product covers; if you go faster without changing the rate, the coverage changes and the application rate per area shifts. The idea that faster ground speed doesn’t matter is not correct. The relationship between granule weight and how far they travel in a rotary spreader isn’t a universal rule; many factors—wind, hopper design, and particle properties—play a role, so it isn’t a reliable statement to rely on. And granular spreaders can be just as accurate as liquid applications when properly calibrated and operated, not inherently less accurate.
