Abstract: A foliage coating and treating apparatus is provided for treating plants with a coating in a manner which advantageously removes excess coating from plants passing through the apparatus. The apparatus includes a coating stage wherein the plants are coated with a coating and a hanging stage wherein the plants are hung on a conveyor. The apparatus further includes a blowing stage wherein the plants are blown with air to promote drying and removal of excess coating and/or preserving liquid. To remove excess coating from the plants, the apparatus includes a coating removal stage which employs a booth having first and second opposed side surfaces between which the plants pass on the conveyor. The booth also includes a plurality of first air vents situated on the first side surface and a plurality of second air vents situated on the second side surface, each of the first air vents being laterally staggered with respect to the second air vents.
