High pressure injection system for applying a pesticide beneath the surface of the ground

A portable handheld application tool for a high pressure injection system for applying pesticide, the portable handheld application tool comprising:

• a handle;
• a manifold head connected to the handle, the manifold head having at least one internal passage;
• a plurality of high pressure nozzles positioned in the manifold head and fluidly connected to the at least one internal passage, the plurality of high pressure nozzles each being operable at pressures of about 25 psi to about 10,000 psi;
• a contact plate mounted to the manifold head, the contact plate having a matrix of openings arranged such that at least two of the openings are spaced from each other both longitudinally and transversely with respect to the contact plate, each opening aligned with a respective one of the high pressure nozzles;
• a source of pesticide fluidly connected to the a plurality of high pressure nozzles;
• and
• a discharge valve moveable between a closed position wherein the pesticide is inhibited from flowing from the plurality of high pressure nozzles and an opened position wherein pesticide flows from the plurality of high pressure nozzles.
