Abstract
A post directed crop spraying apparatus and related method, comprises a pair of opposed substantially vertically extending hood members coupled to a main mounting means. Spray nozzle means are coupled to the main mounting means and disposed between the hood members for spraying liquid material toward the ground between and under the hood members to cross row centers at the base of plants being sprayed. Knockdown bar means are coupled to the main mounting means and extend substantially transversely between the hood members for contacting and for pushing down on weeds during operation of the apparatus. The knockdown bar means are located sufficiently close to the nozzle means to permit the nozzle means to spray liquid material onto the weeds from the bases to the tips thereof and to permit liquid material to be applied in a substantially uniform pattern to the soil around the plant bases.
