ABSTRACT:
A wick applicator assembly for wiping liquid chemical on vegetation, such as weed growth among young field crops, comprises a tractor-mounted elongated bar having a plurality of individual wick stations arranged serially therealong. Each wick station comprises a porous tube individually connected at one end to a common line containing liquid chemical under pressure and at the other end to a common return line for recycling unused liquid to a supply tank. Each tube is covered with a sleeve of fabric material which becomes saturated with liquid seeping from the tube pores for wiping against target vegetation. Adjustable flow restrictors at the inlet and outlet ends of each tube serve to control the saturation level of its sleeve.
