No. 74 Wild oats - biology and control

Following a very wet winter, FAR has received a number of requests for information around managing yellow autumn sown crops. This Arable Extra outlines ways to distinguish between nitrogen and sulphur deficiencies and provides some information to support decision making around crop management.

Wet conditions throughout winter 2025 have created challenges for growers across Canterbury. This Arable Extra addresses issues around 1) autumn sown wheat paddocks with drowned out patches and 2) considerations around sowing autumn milling wheat seed in the spring.

This Arable Update summarises yield and profitability results from 47 FAR trials since 2013, comparing programmes with and without a T0, to help guide your decision-making.

The AIMI survey of New Zealand cereal growers, as at 1 July, 2024 is now available online.

This book outlines trial-specific yields and individual cultivar disease ratings for spring sown wheat and barley cultivars included in the 2024-2025 CPT trials.

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.

Watch the recording for a webinar with FAR Senior Field Officer Ben Harvey on managing herbicide resistance pre-autumn sowing, covering what is herbicide resistance and methods to reduce the risk of herbicide resistance.

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