Abstract: The invention comprises an apparatus for treatment of seeds with liquid insecticide-fungicide and other materials. The apparatus has an opening at its upper end formed by a wall for receiving seeds for treatment with the liquid. A cone is mounted beneath the opening to deflect and spread the seed outward evenly about the cone as they travel down the outer surfaces of the cone. Adjustable plates are mounted in the opening to vary the size for matching the incoming flow to direct the seeds onto the center of the cone, the wall has circumferential overflow openings spaced above the lower edge of the wall. A lever is provided to raise and lower the cone with respect to the wall whereby the movement of the cone upward moves the cone sufficiently close to the wall so as to slow the amount of seeds traveling off the cone to allow the seeds to build up and constantly fill the annular space formed between the cone and wall with a constant overflow through the overflow openings.
