Methods and apparati for screening compounds for agricultural activity has now been developed which employ e.g., intact plants grown in microtiter plates on very small amounts of plant growth media containing a test compound. In comparison to the standard greenhouse screen, the microscreen requires vastly less space, labor, and test compound. However, unlike in vitro screens, responses of intact plants are assayed. Using the microscreen, high-throughput screening of test compounds can be accomplished using whole plant responses as the assay.

A multiple dosage feeder for a cage is provided. The multiple dosage feeder includes a frame having a cage-interior side, a food holding member rotatably mounted on the frame, and a food presentation member disposed on the cage-interior side of the frame. The food holding member holds a plurality of measured dosages of food or other substances, and at least a portion of the food holding member extends to the cage-interior side of the frame. The food presentation member permits access to a single dosage of the plurality of dosages by an animal within the cage. At least a portion of the food holding member is rotatable within the food presentation member so as to expose the single dosage of the plurality of dosages, while the food presentation member prevents access to any remaining dosages on the cage-interior side of the frame.
