Liquid agrichemicals such as pesticides are applied to soil or crops in a continuous stream at low flow rate from microtubes without need for a mixing tank and without clogging of the microtubes during downtime, by a system mountable on a farm vehicle, the system comprising a liquid agrichemical supply tank, a water supply tank, a first conduit connecting the agrichemical supply tank to a manifold feeding the microtubes, a first pump in the conduit, water entrainment means (such as a venturi) and a second, suction pump in the conduit, a second conduit between the water supply tank and the venturi, and other conduits, valves and pressure regulators as appropriate to control the directions and rates of flow, and for recirculation or flushing. By such control, water may be entrained by the venturi for inline admixing with the agrichemical, or the venturi optionally may be bypassed for application of undiluted agrichemical.
