In-furrow chemical inputs, such as fungicides and insecticides, are currently applied as a continuous
band at planting. Focusing these applications at the seed, and minimizing the chemical applied between seeds
could reduce in-furrow inputs significantly. The University of Tennessee Sensors and Controls Laboratory has
developed a seed-specific applicator to apply discrete bands of liquid chemical to individual seeds at planting.
First, seeds are detected in the seed tube, then tracked from the point of detection to the point of chemical
application, and finally sprayed with a variable length chemical band as the seed lands in the furrow.
