Low-to-moderate wheat bulb fly risk, says autumn survey

5 October 2021

AHDB’s autumn survey of wheat bulb fly indicates the general risk trends for this potentially serious cereal pest. Sue Cowgill, who manages pest research at AHDB, explores the latest results and how a lower-risk year can mask higher-risk pest pockets.

Improved phoma forecast suggests late disease onset

29 September 2021

AHDB’s newly improved phoma leaf spot forecast suggests the oilseed rape disease will develop relatively late this autumn. The 2021 forecast has been refined, partly in response to industry concerns that the service had become disconnected from field realities, with the new model focusing on damp, rather than wet, conditions.

Barley rhynchosporium resistance research advanced by PhD

4 August 2021

A glance along the rhynchosporium disease resistance rating lines in the Recommended Lists (RL) reveals plenty of room for improvement. Robert Saville, who manages disease research at AHDB, looks at a PhD project that has provided genetic leads in the quest to deliver more durable resistance to this major barley disease.

LEAF and AHDB exchange knowledge on IPM

20 July 2021

Many farmers have used IPM as an integral part of IFM for years, even decades. Lucy Bates, Technical Manager, LEAF, explains how AHDB research and resources support LEAF farmers in the implementation of best practice across the wide range of farm sizes and sectors that they represent.

Can companion crops give OSR the edge over CSFB?

19 July 2021

Recent AHDB research cited companion crops as one of several options for cabbage stem flea beetle (CSFB) management in oilseed rape (OSR). However, with the evidence to support the approach largely anecdotal, Diss Monitor Farmer, Richard Ling, hopes his on-farm trial will help tease out the benefits.

Fatal attraction: the wheat chemicals aphids can’t resist

12 July 2021

With pesticide options for aphid control waning, an AHDB PhD studentship aims to turn the tables on these damaging pests. Sue Cowgill, who manages pest research at AHDB, investigates how the work exploits the power of natural chemicals released by old wheat varieties.

Septoria tritici disease resistance in winter wheat

2 July 2021

Some winter wheat varieties in our Recommended Lists (RL) trials appear to show higher levels of septoria than would be expected from the disease ratings published in the current RL (2021/22 edition). With disease assessments currently being undertaken by RL trial inspectors, Paul Gosling, who leads the RL at AHDB, takes a look at the emerging picture.

Sclerotinia: 2021 disease-pressure overview

24 June 2021

The 2021 risk period was relatively cool. This delayed flowering and extended the flowering period. It also resulted in a relatively low number of weather-based infection risk alerts and, generally, low spore levels, AHDB crop protection scientist Robert Saville reports.

How drill date affects septoria disease resistance ratings in winter wheat

23 June 2021

With new research results showing how septoria disease resistance shifts in response to drilling date, Robert Saville, AHDB Crop Protection Scientist (disease), looks at what it might mean for control in 2021–22.

How drill date affects CSFB management in oilseed rape

21 June 2021

Now the risk from cabbage stem flea beetle (CSFB) has passed for this year’s oilseed rape (OSR) crop, it is time to take stock and plan ahead. In particular, it is essential to consider the drilling window and how this affects pest pressure – of both CSFB adults and larvae.

‘Interesting’ wheat yellow rust isolates identified by UKCPVS

19 March 2021

The UK Cereal Pathogen Virulence Survey (UKCPVS) continues to detect new and interesting wheat yellow rust isolates associated with unique crop disease patterns. AHDB crop scientist Robert Saville reports on the latest developments and what it means for management.

Can decision support systems narrow the odds on making better choices?

4 March 2021

Some decisions are so simple that we don’t even know we are making them. Others, such as deciding the appropriate course of action to prevent, detect and control pests, weeds and diseases, are time-consuming and complex. That’s why AHDB is collaborating in a pan-European project to put robust decision support systems (DSS) at your fingertips. Emily Pope, Senior Knowledge Transfer Manager, explains.

How the autumn and winter changed BYDV risk in cereals (IPM blog)

2 March 2021

Due to their prolific reproduction (during asexual reproduction, females are born ‘pregnant’), aphids can build up on crops rapidly. They are also notorious for developing resistance to commonly used insecticides and, consequently, can be a headache to manage. As we enter spring, Charlotte Rowley, who manages pest research at AHDB, reflects on the recent autumn/winter, including the effects on aphid pressures and the spread of Barley yellow dwarf virus (BYDV) in cereals.

Cabbage stem flea beetle (CSFB) control collaboration

9 February 2021

When a big issue arises, everyone wants a solution. An all-too-human response is for everyone to react in their own ways. Although better than nothing, it is not often an efficient route to an industry-wide answer. AHDB pest scientist Charlotte Rowley reveals how the UK has found itself at the heart of a coordinated attack on CSFB.
