The A-1 EZ Feeder is simple to operate. Just set for the desired amount, place the tube near the surface of the container and depress the plunger. The material is then deposited into the container. The tube will easily fit through thick foliage keeping the chemical off the plant. May be used for bench applications by simply removing the extension tube from the funnel. Adjustable application range of 1/8 - 1 1/2 teaspoons (.75 - 5 grams).
