ABSTRACT:
Normally crops are sprayed with herbicide or the like by means of expensive and heavy spray bar equipment pulled or carried behind a tractor. The present device comprises a pair of spaced and parallel bars which include porous tubes or wick-like devices connected to a tank of herbicide or other chemical so that a film of the liquid chemical is maintained on the surface of the tubes. These are mounted transversely behind a tractor together with a supply tank and the tubes can be raised and lowered relative to the ground so that they can be drawn across the crops and adjusted so that the tubes engage the weeds but not the crops as the weeds normally grow higher than the crops in the initial growth stages.
