This invention relates to an improved method and apparatus for application of agrochemicals from a moving vehicle. It utilizes a multiple chemical infusion system for mobile spraying of liquid mixtures at present, controlled, and monitored application rates which integrate ground speed, solute concentration, diluent volume and spray swath path width using dynamic, real time software in a digital computer unit with a read only memory chip. Microprocessor controlled peristalic squeeze pumps, capable of simultaneous or independent application of a plurality of chemicals, infuse chemicals to be applied into solvent water where the mixture is delivered to a boomless spray assembly by a centrifugal pump or application. The microprocessor is controlled by the operator of the moving vehicle.
