Growth of <i>Eucalyptus nitens</i> after application of herbicide to control parsley dropwort

Abstract

Problems in establishing eucalypt trials on some Northland sites were caused by severe competition from parsley dropwort (Oenanthe pimpinelloides). In a trial Eucalyptus nitens seedlings grew well with the application of a herbicide, dichlobenil, which controlled parsley dropwort and other weeds at rates of 0.74 g/m 2 and 1.15 g/m2. The seedlings grew poorly in the absence of herbicide. Bare-rooted seedlings and smaller container-grown seedlings were included and the barerooted seedlings remained larger after one growing season, which would be an advantage in competing with weeds the following season.
