From the Ground Up, Issue 76

Stem rust (Puccinia graminis subsp. graminicola) is the most damaging of the ryegrass diseases. This update discusses 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.

This Herbage Update defines a more accurate harvest window for perennial ryegrass seed crops. Read more here.

Welcome to the revised 2025 version of  The drying and storage of grain and herbage seed, first published in 1999. The book comprises six chapters that cover grain characteristics and their reaction to climate, the importance of seed moisture, the drying system, the storage environment, storage pests and their control, and construction considerations. These have been edited and updated by FAR staff and independent experts from the original chapters written by the late Murray Hill.

A velvetleaf find in a paddock that has been ‘clean’ for seven years, is a clear reminder of how long this weed’s seed will remain viable.

Between January and May 2025, FAR and harvester specialists conducted a comprehensive study to quantify the grain and seed left in the paddock by New Zealand growers and identify opportunities to optimise harvester performance. 

This Cereal Disease Management Strategy summarises the results of FAR research conducted between 2022 and 2024. It provides an overview of the most important diseases currently affecting wheat and barley in New Zealand, and outlines a range of cereal disease management strategies and approaches derived from numerous FAR research trials. 

Growers are reminded to report any grass weeds that appear unfamiliar or could resemble black-grass (Alopecurus myosuroides). Early reporting remains one of our strongest tools for protecting the industry.

This report outlines a fungicide evaluation field trial conducted during the 2023-24 growing season, evaluating the efficacy of a range of fungicides targeting oomycetes for managing cocksfoot downy mildew pathogens.

The AIMI survey of New Zealand cereal growers, as at 10 October, 2025 is now available online.
