Abstract

An injection apparatus for treating soil adjacent a structure includes a handle and a manifold head connected to the handle. The manifold head has a first high pressure nozzle, a second high pressure nozzle, and a contact member having at least one opening therein. The contact member is configured to rest on the ground surface during operation of the injection apparatus. The first high pressure nozzle is adapted for emitting a discharge stream of pesticide through the at least one opening in the contact member for injection of the pesticide into the soil. The discharge stream from the first high pressure nozzle is emitted in a first direction. The second high pressure nozzle is adapted for emitting a discharge stream of pesticide through the at least one opening in the contact member for injection of the pesticide into the soil. The discharge stream from the second high pressure nozzle is emitted in a second direction that is angled relative to the first direction of the discharge stream of pesticide emitted from the first high pressure nozzle. A supply of pesticide is in fluid communication with the first and second high pressure nozzles.
