vary, based in part on the distance the plant is located from walkways. (and therefore,
on the likelihood of the damage being observed.
Airblast sprayer - CORRECT ANSWERS-Pesticide application equipment that uses a
stream of air from a fan to break up and distribute the pesicide onto the plant that is
being treated.

should be removed prior to planting. The burlap should (optimally) be removed as much
as possible also, as amany types of modern burlap contains synthetic fibers that will not
