ABSTRACT:
An irrigation deterrent tube, particularly adapted for drip or trickle irrigation, the tube having, normally, a flat configuration when free of internal pressure, and expansible to an essentially cylindrical configuration, when pressurized, the tube having laterally projecting webs which tend to be the first to be bitten by a rodent while exploring the presence of the irrigation tube; the lateral margins of the webs may be enlarged to contain a concentration of a deterrent or toxic material. In one embodiment, the tube and webs form a single extrusion, in other embodiments, the tube and webs may be separately extruded and subsequently joined together.
