Improved apparatus and method for controlling weeds and undergrowth

摘要

An apparatus and a method for controlling weeds and undergrowth, as well as insect infestation. The apparatus is characterised by its construction to include a heater (34) whereby liquid spray material is first heated to a temperature of from about 100 DEG F to about 240 DEG F and then sprayed on the substance to be controlled. The apparatus further includes an insulating apron (90) for maintaining the heated spray material in close contact with the substance onto which it is sprayed, while at the same time insulating the heated spray and treated substance from ambient conditions. A variety of fluid conduits and controls are provided so that a variety of spray liquids may be applied in predetermined fashion. The apparatus can be attached to a standard tractor (10) for ease of use. The method is characterised by its utilisation of agricultural chemicals in amounts from virtually 0% to about 50% of their current recommended dose rate.
