Abstract

Basal bark and foliar applications of triclopyr ester, 2,4,5-T ester and ground application of hexazinone were evaluated for the control of false sandalwood (Eremophila mitchellii).
Triclopyr ester and 2,4,5-T ester gave 93% and 95% kill, respectively, of false sandalwood when applied as a basal bark spray at 10 g L^-1. Misting treatments with triclopyr ester in water (10, 20 and 50 g L^-1) were ineffective.
Hexazinone applied on a grid pattern at rates of 4 and 8 kg ha^-1 gave similar control to a basal bark spray of 2,4,5-T ester at 10 g L^-1. Individual treatment of false sandalwood with 1g hexazinone resulted in greater than 95% kill of multi-stemmed plants up to 1.75 m tall.
