Integrated Weed Management Workshop (booklet)

Plantain has become an increasingly important component of pasture seed mixes, driven in part by heightened environmental concerns regarding nitrate leaching from grazed pastoral systems. Nitrogen (N) fertiliser management is widely regarded as the principal agronomic lever for increasing plantain seed yield, especially in environments with low inherent soil fertility. This project aims to improve the agronomy of plantain seed production by identifying optimal biological and economic N application rates.

Perennial ryegrass (Lolium perenne L.) is the main ryegrass species grown for seed in New Zealand, supporting both pasture and turf markets. Canterbury leads production, with around 12,000 ha sown annually. This study pulls together results from ten Canterbury field trials to assess how different fungicide programmes and timings affect seed yield. It compares early versus late applications and offers practical advice to help growers improve rust control and maximise returns.

Catch up on the booklet for the white clover seminar held April 2026. 

A large-scale research project is establishing a diverse and sustainable toolkit of weed management strategies for cropping farmers in the face of rising rates of herbicide resistance. 

This arable extra discusses how emergence timing influences Vulpia development, flowering, and seed production Canterbury field conditions.

Sometimes, the only way to bring in a crop is to harvest in conditions that are less than ideal. If you find yourself in this situation, it’s a good idea to think about your combine settings to help reduce losses and prevent unnecessary breakdowns. This Technical Update  covers some of the key points for getting the job done .

Read information on scouting and the current black-grass situation in this January 2026 update.

Arable growers worried that some weeds in their crops may have developed herbicide resistance can now get the suspected plants tested for free. Find out how you can take part here.
