The Autumn Cereal Cultivar Evaluation Book for 2024/25 is now available to read.

Planting a crop consisting of multiple cereal cultivars (cultivar mixtures) enhances genetic diversity, which can improve both seasonal and long-term agronomic performance and slow or reduce disease spread. To assess the viability of this approach for feed wheat production under current commercial conditions in New Zealand, FAR conducted a series of field trials in Chertsey, Mid Canterbury, between 2021 and 2024.

This Maize Update discusses key issues for consideration in the choice and establishment of over-winter cover crops, along with the results of a five-year trial at FAR’s Northern Crops Research Site which researched the potential for over-winter cover crops to suppress weeds in the following no-till maize grain crop.

This FAR Focus on maize weed management covers research on issues maize growers currently face, including; Herbicide resistance, problem weeds, herbicide options and on-farm biosecurity. 

Seed and Grain Readiness and Response Incorporated (“SGRR”) is a biosecurity entity for the arable sector. It was established in 2020 under the Government Industry Agreement for Biosecurity (GIA). It is currently collecting levies to cover the costs of the two biosecurity incursions, black grass and fall armyworm.

Current status: FAW populations continue to develop across New Zealand. Northland awaits the third main moth flight of the season, with the key time for scouting and decision-making approaching. Maize grain and sweetcorn growers should be particularly vigilant during this period.
