An apparatus for applying a fluid such as an insecticide to grain or similar material that is carried by a conveyor. A flap device which is formed from a sheet of resilient flexible material is pivotably mounted at one of its ends to a supporting structure which is located above the conveyor, and the flap device is positioned to contact and ride over the material that is carried by the conveyor. A distributor extends across the width of the flap device and includes a series of distribution channels which open to a lower surface of the flap device. The fluid is delivered to the distributor and is directed into the material which, in being carried by the conveyor, is contacted by the flap device. A sensing device is incorporated in the apparatus for detecting the degree of pivotal movement of the flap device as it rides over the material on the conveyor and, thus, for providing a measure of the quantity of material on the conveyor.
