ABSTRACT:
An installation for the controlled dosing of an irrigation flow with a herbicide particularly for detecting root growth into the outlets of an underground drip irrigation line, includes a sealed container and a slow release herbicide material wherein a portion of the flow is directed through the herbicide impregnated material so that herbicide is controllably released into the diverted flow, and the diverted flow is reintroduced into the irrigation flow.
