Abstract
A dispenser for agricultural chemicals generally has a small plastic plate defining an affixing enclosure for fitting the dispenser over or around branches, vines etc. The plate has an opening therein. A container for the chemicals having one unenclosed section is attachable to the plate with the unenclosed section substantially aligned with the opening in the plate for emitting the agricultural chemicals to the environment. The opening in the faceplate can be at least partially surrounded by a raised edge and this edge may contain a lip for securing the container to the plate via a snap or sliding fit. Certain other options include forming the faceplate with small nubs which jut outwards over the opening in the faceplate. When the container is attached to the plate, these nubs prevent the chemical within the container from being jostled loose and also limit the exposed surface area of the contained chemical. Variously sized containers are attachable to the plate to selectively choose the rate of diffusion of the chemical through selection of effective surface area exposure.
