Abstract

Subirrigated pot-plant systems were developed for greenhouse simulations of field methods being tested for herbicidal control of saltcedar (Tamarix pentandra Pall.). The methods included: over-the-top spraying; soil injection; soil layering, with whole plants transplanted onto the herbicide layer; and soil layering by severing the roots and concomitantly injecting herbicide. Existing foliar application techniques were improved for greenhouse testing of herbicides and results from preliminary tests were apparently similar to literature reports of limited efficacy in the field. Preliminary results from these greenhouse techniques showed that root zone applications, either by soil layering or soil injection, were very effective; stem or foliar applications were less effective.
