Abstract: An apparatus for preparing a biofungicide mixture for application to harvested fruit. The apparatus includes a storage container for holding a dry biofungicide component. The storage container is attached to a conduit which has a screw conveyor rotatably disposed within it for transferring a desired amount of the dry biofungicide component to a preparation tank. A feed motor is attached to the conveyor and controls its rotation. An agitator mounted within the preparation tank mixes the biofungicide component with water to form a biofungicide mixture. A water level control device determines the level of the liquid within the tank. The water level control device controls flow of water into the preparation tank by actuating a valve along a water conduit. The water level control device also controls the startup of the feed motor. A transfer pump transfers biofungicide mixture from the preparation tank to an application tank.
