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.
Claims12
In an underground drip irrigation system including a drip irrigation line having successive spaced apart drip outlets, an installation for deterring root growth into said outlets comprising an irrigation supply conduit coupled to said drip irrigation line;
- a bypass having a bypass inlet flow-coupled to an upstream portion of the conduit, a bypass outlet flow-coupled to a downstream portion of the conduit upstream of said drip irrigation line;
- a single sealed container having a flow inlet flow-coupled to an upstream portion of the bypass, a flow outlet flow-coupled to a downstream portion of the bypass;
- a flowpath in the container provided between the flow inlet and the flow outlet thereof and extending through at least a major dimension of the container;
- and a slow release herbicide impregnated material selected for the group consisting of synthetic polymer and rubber and located within said container;
- said container and said bypass being arranged such that a portion of irrigation flow passes through said container and is controllably dosed with said herbicide and is reintroduced into said conduit to pass through and out of said outlet.
