Abstract
A subsurface drip irrigation (SDI) pipe including a polymer water conduit with drippers spaced along a length of its wall and one or more essential oils (EO) adsorbed to a nanoclay (NC)/polymer structure so that EO is delivered to soil surrounding the SDI pipe.
Claims16
A subsurface drip irrigation (SDI) pipe comprising:
- (a) a polymer water conduit with drippers spaced along a length of its wall;
- and
- (b) one or more essential oils (EO) adsorbed to a nanoclay (NC)/polymer structure forming at least a portion of the SDI pipe so that EO is delivered to soil surrounding the SDI pipe as a sole active ingredient to mitigate root invasion.
A method comprising:
- incorporating an essential oil (EO) adsorbed to a nanoclay (NC)/polymer structure as a sole active ingredient to mitigate root invasion in at least a portion of a subsurface drip irrigation (SDI) pipe.
An irrigation dripper comprising:
- polymer having incorporated therein one or more essential oils adsorbed to a nanoclay/polymer structure without any other active ingredient to mitigate root invasion.
