No. 109 Have wild oats in Canterbury become resistant to herbicides?

This arable extra discusses trial results from the 2024 herbicide screening trial at Kowhai Farm in Lincoln, Canterbury. 

This update outlines the results of five years of trials exploring pre-desiccant options for managing bulky white clover crops, aiming to reduce rapid leaf regrowth following diquat desiccation under wet or high-fertility conditions. Achieving effective desiccation required balancing this process with post-harvest regrowth, as clover seed crops are often used for lamb grazing on New Zealand cropping farms.

This FAR Focus outlines the key practices required to grow cocksfoot seed crops, covering topics such as crop establishment, nutrient requirements, crop management and harvesting. Topics outside the scope of this booklet include emissions profiles and off-farm considerations such as seed cleaning etc.

Pure Oil NZ and FAR are collaborating to monitor oilseed rape (OSR) paddocks to identify strategies to improve yields. Their work has identified that many growers could reduce the amount of nitrogen applied to OSR crops without impacting on yield or profit.

This report describes 2023 data from FAR’s ongoing herbicide screening trial at Chertsey, mid-Canterbury, where the efficacy and crop safety of a number of new and old herbicides were tested against several problematic weed species and in a number of common crops. This is the third consecutive year that FAR has run this trial, after a nine-year break.

This handout covers herbicide resistance management, PGRs, nitrogen and disease management.
