Project seeking farmers to investigate crop physiology traits
A project led by the Agriculture and Horticulture Development Board (AHDB) is set to investigate crop physiology traits in winter wheat that enhance weed competitiveness in low-input and organic farming systems.
The initiative will support cereal and oilseed growers with sustainable strategies to naturally suppress weeds, reducing reliance on herbicides and supporting the transition to more environmentally friendly agricultural practices.
According to the AHDB, the project builds on findings from the 2022/2023 review of the recommended lists of cereals and oilseeds, where levy payers highlighted the importance of variety competitiveness against grass weeds.
It said that with a growing body of evidence supporting the use of competitive varieties for weed suppression, this new research aims to pinpoint the specific varietal traits that deliver this benefit – informing both farmer decision-making and long-term plant breeding strategies.
Delivered in collaboration with RSK ADAS Ltd, Cope Seeds UK Limited, the Organic Research Centre (ORC), and UK Grain Lab, the project will run from June 2025 to December 2027.
It will involve a UK-wide network of on-farm trials focused on identifying key traits that correlate with weed competitiveness under organic and low-input conditions.
The AHDB said that the results will contribute to a "robust, multi-year dataset", which will enhance the information gained through RL crop physiology assessments.
The project will equip farmers with additional insights into variety selection – helping them choose winter wheat varieties that offer greater natural weed suppression.
Senior knowledge transfer manager at AHDB, Henny Lowth said: "We know that managing weeds without chemicals is a key challenge for growers in low-input and organic systems.
"This project represents a major step toward providing clear, evidence-based guidance on how variety choice can support integrated weed management."
"We're excited to be working with our partners and the farming community to deliver meaningful, field-tested results," Lowth added.
For farmers interested in taking part and hosting an on-farm variety trial, the form is available online.

Germs: The dirtiest items are ones we might least expect but there are ways to protect yourself
One of the legacies of the Covid pandemic is an increased awareness of microbes. Many bacteria and viruses lurk on surfaces we touch everyday. Most are harmless, but a few of these bugs can make us seriously ill . Writing in The Conversation recently, Dr Manal Mohammed, senior lecturer in Medical Microbiology at the University of Westminister, looked at how some of the dirtiest items in our lives are ones we might least expect. With many of us travelling during the summer months, she highlighted the hidden dangers of items, such as hotel TV remote controls and airport security trays. I was surprised to read that hotel remote controls can be dirtier than toilet seats. Then again, they are rarely sanitised, with research showing they harbour common bacteria including E. coli and Staph. aureus. READ MORE So, how can we protect ourselves from becoming infected? We can either wipe the remote with an antibacterial wipe or place the remote in a transparent plastic bag before using it. Airport security trays are another source of potential infection. Despite being handled by hundreds of people daily, they are rarely cleaned. Research has found high levels of bacteria on the trays, including E. coli. And a study that looked for viruses on surfaces found in airports found that security trays had the highest concentration of respiratory viruses. Dr Niina Ikonen, a virology expert, and colleagues from the University of Nottingham and the Finnish National Institute for Health and Welfare collected surface and air samples from Helsinki-Vantaa airport. [ How your tongue and gait can give important clues as to your overall health Opens in new window ] Research has found high levels of bacteria on the airport plastic security trays, including E. coli. Photograph: Smith Collection/ Gado/ Getty Images Some 20 million passengers pass through Finland's busiest airport every year, making contact with surfaces such as armrests, escalator handrails, toys in the children's play area, trolley handles and luggage trays. Researchers swabbed these surfaces and tested them for viruses such as influenza, respiratory syncytial virus, adenovirus, rhinovirus, and coronavirus. The results showed viruses were present on 10 per cent of the surfaces examined, with rhinoviruses - the culprit for the common cold - the most widespread. And while plastic security trays had the highest concentration of viruses, perhaps the most unusual positive swab location was the buttons on the credit card payment pad at the airport pharmacy. In terms of protection, either wash your hands after security or use hand sanitiser, especially before eating or touching your face. Shopping trolley handles are another potential source of infection. A US study found that more than 70 per cent of shopping trolleys were contaminated with coliform bacteria, a group that includes strains like E. coli, often linked to faecal contamination. A separate study found Klebsiella pneumoniae and Pseudomonas species on trolleys. It would help if we could get into the habit of cleaning shopping trolley handles before use. Mobile phones have become a big part of travel, with airlines encouraging us to display boarding cards on their screens. Frequent handling and their warmth make them ideal for bacterial contamination. Research shows phones can carry harmful bacteria including Staph. aureus. Mohammed advises not using our phones in bathrooms and to clean them with a slightly damp microfibre cloth and soap. [ The way to a human's brain and immune system is through the gut Opens in new window ] Flushing a toilet releases a plume of microscopic droplets, which can land on nearby toothbrushes. Photograph: Getty Images When we are on the move, staying in hotels or Air BnBs, we have to use unfamiliar bathrooms. It's worth being careful how we store our toothbrushes in each new location as flushing a toilet releases a plume of microscopic droplets, which can land on nearby toothbrushes. Research found that toothbrushes stored in bathrooms can harbour E. coli, Staph. aureus and other microbes. If we rinse the toothbrush after each use, let it air-dry upright and store as far from the toilet as possible, we can protect ourselves from this source of microbes. Finally, take care if sharing nail and beauty tools with your travel companions. Nail clippers, cuticle pushers and other grooming tools can spread harmful bacteria if they're not properly cleaned. We can't avoid all germs. But with a few good habits you can help protect yourself and others. mhouston@

UK taskforce recommends ‘targeted' bird flu vaccination trial in turkeys
A new report from a UK joint industry, cross-government taskforce has recommended a targeted on-farm vaccination trial in turkeys – one of the most susceptible poultry species to bird flu. The taskforce, which was set up to examine the UK's position on bird flu vaccinations and make recommendations, in general supports the principles of vaccination but has warned that 'significant uncertainties remain'. Its report highlights during the 2022 to 2023 season, turkeys had the highest proportion of infected to uninfected premises of any species. 'Economic modelling suggests that turkeys offer a favourable value for money profile due to their higher per-bird value and shorter production cycles. 'A targeted trial in this sector would generate UK-specific evidence on vaccine efficacy, duration of immunity, and surveillance feasibility,' the taskforce outlined. Current UK policy does not permit the vaccination of birds against highly pathogenic avian influenza (HPAI) – except in zoos in England and Northern Ireland. Bird flu According to the UK taskforce 'stringent biosecurity on farms is the best way to prevent infection of poultry flocks'. But it also recommended a series of actions – including an on-farm vaccination trial in turkeys – and exploring laboratory capacity for surveillance purposes, in order for the UK to find an effective way to protect poultry flocks from the disease. In its opinion there are three main vaccination strategies which could be implemented in the UK including: Allowing preventative vaccination either nationwide or within targeted geographic regions or species group; Maintaining the UK's current policy and only allowing vaccination in zoo birds; Use of emergency vaccination based on risk assessment and agreed trigger points. According to the taskforce 'significant uncertainties remain and the taskforce cannot make a final recommendation without more evidence'. 'No single product fulfils all of the criteria agreed by the taskforce as being an ideal vaccine, due to diversity in the dosing regime and species for licensed use,' it stated. There are currently three vaccinations authorised for use in GB and NI including nobilis Influenza H5N2 Emulsion for Injection for Chickens, Vectormune HVT-AIV Concentrate and Solvent for Suspension for Injection for Chickens and Innovax-ND-H5 Concentrate and Solvent for Suspension for Injection for Chickens. In its report the taskforce detailed that its analysis found that 'overall vaccination of all poultry in the UK would likely offer poor value for money'. 'Given vaccines are not fully effective at preventing outbreaks, it is unlikely the full cost savings from intervention would be realised. 'Similarly, there is the possibility that uptake is lower than estimated, reducing effectiveness,' it outlined.
