ABSTRACT:
A liquid applicator roller apparatus evenly applies liquids to plants even when moving over uneven terrain. A sponge extends into engagement with the peripheral surface of the horizontally mounted applicator roller for depositing a film of liquid on the roller surface just before it contacts plants. Liquid is supplied to the sponge, and a metering device controls the flow of liquid to the sponge to ensure that the elevated end of the sponge is fed with liquid when one end is higher than the other. The metering apparatus includes a housing having a central bore parallel to the roller, and liquid connectors at opposite ends of the bore having sealing surfaces which cooperate with a metal ball that rolls within the bore. A supply line extends into the housing from the top, to supply liquid to the bore.
