Question

What are the uses of a sprayer?

Answer 1

There are lots of different kinds of sprayers but I gather from your other questions you are interested in the agriculture type.  There are all different sizes from smaller than a quart  to giant tractor mounted units that can cover many feet at once.  However, they are all used for the same purposes.  To spray liquid fertilizers, insecticides, herbicides, or fungicides.

Answer 2

To spray chemicals on plants to control insects and diseases. Also used for weedkiilers, use seperate sprayer for this purpose.
