Effects of rate of application of triclopyr on wandering jew (tradescantia fluminensis vell.)

Abstract

Wandering Jew (Tradescantia fluminensis Veil.) is a common weed in canopy-depleted indigenous forest remnants in New Zealand. In this study triclopyr was applied to dense stands of wandering Jew at a range of rates in each of two experiments (Diamond Harbour in the South Island and Te Pahu in the North Island) to determine its effects on the weed and subsequent regrowth. The cover of wandering Jew was initially reduced by 80-100% with herbicide application. At about 1 year after application of the herbicide, the wandering Jew had regrown to about 3-50% cover, depending on the rate of triclopyr applied, and some indigenous seedlings had begun to appear. However, the survival of these seedlings was minimal.
