Weeds

FAR weed research focuses on herbicide resistance and trials to assess the efficacy of new herbicides.

PROJECTS

Herbicide resistance

Herbicide resistance is an increasing threat for the New Zealand arable industry. A number of weeds are becoming harder to kill particularly wild oats and Italian ryegrass in Canterbury.

For further information on herbicide resistance.


Grassweed herbicide trials

Grassweeds are a continuing problem in New Zealand cereal and herbage seed crops. Several key grassweeds have been an increasing problem in recent years. Grassweeds compete with crops for water, light and nutrients, and in the case of members of the Bromus genus, harbour take-all. This research was designed to indicate potential herbicide options for a range of problematic grasses.
