<p>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 °F to about 240 °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.</p> |
