ABSTRACT:
A method of metering and spraying toxic pesticide comprising a vacuum line having a first end attached to a vacuum source, such as an intake manifold on an internal combustion engine, and having a second end communicating with the inside of a metering chamber. A float valve in the metering chamber on the second end of the vacuum line to close the vacuum line or in a vent passage to the metering chamber is adjustable in the metering chamber to control the level to which liquid is drawn into the metering chamber. A pesticide transfer line is connected from the metering chamber to a source of liquid pesticide positioned at a level below the metering chamber such that a vacuum in the metering chamber will draw pesticide from the pesticide source through the pesticide transfer line into the metering chamber. When the surface of the liquid reaches the float valve flow of liquid through the liquid transfer line to the metering chamber is terminated. After the liquid has been deposited in a spray tank with a predetermined amount of water to dilute the liquid pesticide, a pump is used to spray the liquid through a spray nozzle.
