A mechanical device was developed for attachment to mechanical toppers mounted on a high clearance sprayer that permits topping concurrent with precision application of sucker control chemicals. A pair of hydraulically driven belts actively guides a plant into the topper (for bud/flower removal) and then positions the plant directly beneath a small spray manifold. Another feature senses the stalk position and opens a solenoid for one-eighth second, thereby applying 15 ml spray in a confined pattern (ca. 12-18 cm dia.) directly over the stalk. In initial tests in 1995, complete sucker control was obtained on 65% of the plants in the early flower stage using a single application of Off-Shoot T. Design modifications and a second topping and chemical application to increase sucker control will be tested in 1996. Potential benefits are reduced: 1) quantity and cost of chemicals, 2) labor and operational costs, 3) chemical release into the environment, and 4) chemical residues.
