In New Zealand, pastoral farming for dairy and meat production is the major land use. As
with any agricultural production system, weeds are a threat to efficient pasture production in …

ABSTRACT Although New Zealand is developing an increasing number of herbicide-
resistant weed populations, it has a much lower incidence of herbicide resistance than …

To estimate the prevalence of herbicide-resistant weeds, 87 wheat and barley farms were
randomly surveyed in the Canterbury region of New Zealand. Over 600 weed seed samples …

Herbicide-resistant weeds are serious threats to agricultural production. Since a review
published in 1996, the number of different examples of weed biotypes developing resistance …

BACKGROUND Perennial ryegrass (Lolium perenne) has developed resistance to
glyphosate within New Zealand vineyards following many years of herbicide application …

Recently, the acetohydroxyacid synthase (AHAS) amino acid substitution Asp376Glu was
detected in a Lolium perenne population originating in France. This is the first documented …

Herbicide resistance has repeatedly developed under intensive herbicidal weed
management regimes globally with 255 species having resistant biotypes. In New Zealand …

This study examined if glyphosate-resistant populations of Lolium multiflorum and Lolium
perenne from some New Zealand vineyards were still susceptible to glufosinate and …

Glyphosate, currently the world's most extensively used herbicide was on the market for
more than 20 years since its introduction in 1975 without reported evolution of resistant …

Herbicide resistance in weeds necessitates the continued monitoring of herbicide resistance
evolution in weed species. This study investigated the level of paraquat resistance in two …
