VEGETATION CONTROL USING HIGH PRESSURE LIQUID SPRAY

摘要

An apparatus and method for controlling vegetation, as well as insect infestation, as are typically encountered in agricultural environments is disclosed. The apparatus is characterized by its construction to include a high pressure pump (26) whereby liquid spray material may be applied to vegetation at a pressure from about 100 psi to as much as about 4,000 psi. The apparatus further includes a heater (34) whereby the liquid spray material may be heated to a temperature of from about 100 DEG F to about 240 DEG F before it is sprayed. The apparatus is constructed so that it can be attached to a standard tractor (10) for ease of use. The method of this invention is characterized by its utilization of a high pressure spray so that agricultural chemicals in amounts from virtually 0 % to about 50 % of their current recommended dose rates can be used with efficacy.
