‘Strongest set' of oilseed rape pest management strategies released
The further we get into the summer, the warmer temperatures will become, and the higher the risk of pests and diseases among crops.
Therefore, farmers need to be diligent in checking for signs of pests and diseases within crops, in order to prevent reductions in quality and yield.
With this in mind, the strongest set of cabbage stem flea beetle (CSFB) management strategies to date has been released today (June 11).
The strategies, which were compiled by a large consortium of stakeholders passionate about the future of oilseed rape in the UK, will reduce the risks associated with growing this important break crop, especially when combined.
To prepare the strategies, the group evaluated the latest evidence, including data generated by AHDB-funded research.
AHDB will continually review the management strategies and adapt them in response to new sources of robust evidence arising from research activities.
Sacha White, Agriculture and Horticulture Development Board (AHDB) lead crop protection scientist said: 'The amount of oilseed rape grown in the UK in recent years has fallen sharply, partly due to CSFB pressures.
'However, the demand for oilseeds remains strong and the crop provides good market and rotational opportunities.
'These evidence-based management strategies will reduce the risks associated with the pest and stack the odds in the favour of farmers', she added.
Pest management strategies
The AHDB has outlined the top ten CSFB management strategies as follows:
Ditch the date: Do not stick to traditional calendar dates – sow early or late to avoid the peak migration period, which usually occurs during late August to mid-September. Good establishment: Always wait for adequate moisture before sowing, use the best seed, promote good seed-to-soil contact, ensure adequate nutrition and select varieties with appropriate vigour. Keep your distance: Any distance (space and time) between previous and current crops will improve the chance of success. Improve larval tolerance: Fewer, bigger plants will stand up better to larval attack. Make use of muck: Apply organic materials, which can reduce beetle damage and support crop growth.
They have also advised carrying out companion cropping and intercropping, which can shield crops from CSFB, and using sacrificial strips of brassica (e.g. turnip) or oilseed rape volunteer trap crops to lure beetles away.
The AHDB also called on farmers to stop using pyrethroids as 'resistance is real and the chemical can harm beneficial insects'.
The board recommended cultivating OSR stubble soon after harvest to target emerging CSFB and integrating other tactics to suppress the pest.
The management strategies were identified as part of the Oilseed Rape Reboot initiative.
Led by United Oilseeds, the initiative established an advocacy group to provide a collaborative path to help UK farmers grow stable and profitable OSR crops.

Harkin praise for MSLETB during visit to her home town
Her visit is part of a series of visits to all 16 Education and Training Boards across the country. Her visit also included an afternoon at the Northside Community Centre. Minister Harkin commended Tom Grady and the team at MSLETB for the breadth of educational and training opportunities they are offering over a huge geographical area, 'With a catchment area that stretches from Inishturk and Belmullet in West Mayo to Mohill and Rossinver in Leitrim it overs the largest geographical area of all ETBs and services a population of 240,000 people,' Minister Harkin said. 'Despite the numbers and the huge area, MSLETB provides a responsive, comprehensive education and development service to about 15,000 learners on 27 different sites in 40 different buildings and has a budget of almost €57m. 'They play a pivotal role in the social and economic development of the region and I was glad to be here to listen to the success stories and hear about the challenges.' As part of the visit Minister Harkin called to the Northside Community Centre, which she described as a hive of activity and learning that plays a key role in empowering individuals, supporting families and communities. 'Here today I saw first-hand some of the work that is being done and met people of all ages whose lives are being transformed by the opportunity to learn and explore everything from cookery to film-making.' Founded in 1996, the centre is managed by Sligo Northside Community Partnership a voluntary board of directors from the local community. It offers a range of services, including room rental, educational and learning activities, pre-school and after-school services, drug and alcohol addiction support services, and counselling support services. In the 2024/25 period, approximately 200 learners enrolled in MSLETB-funded courses at the centre. MSLETB has provided €28,000 in funding to support these initiatives. Everything from film-making to cookery and art is offered at the centre to a wide range of participants. Minister Harkin concluded, 'The Sligo Northside Community Centre exemplifies the spirit of community-led development, and the thngs that can happen when statutory bodies like the MSLETB and the community come together. 'I am committed to supporting such initiatives that foster inclusion, education, and empowerment across our region.'

Calls for suspension of EU-Israel Association Agreement
The head of a leading Palestinian human rights organisation has urged the European Union to suspend the EU-Israel Association Agreement in light of Israel's deepening military campaign in Gaza and the planned expansion of illegal Jewish settlements in the West Bank. Issam Younis, managing director of the Al Mezan Centre for Human Rights, was addressing a meeting in Brussels on the situation in Gaza and the West Bank hosted by the European Endowment for Democracy (EED), an EU-funded organisation supporting democracy in the Middle East. "If not now, when? Shall they wait until how many Palestinians are killed - more than 54,000," asked Mr Younis. "We have no need to prove that Israel is violating the basic principles of international law and international humanitarian law. "It's well documented." Last month a majority of EU member states, including Ireland, signed up to a Dutch proposal for a review of the Association Agreement, on the basis that Israel may be in breach of its binding human rights and international humanitarian law clauses. On foot of that shift in member state opinion, the EU's foreign policy chief Kaja Kallas has begun the review process, with the possibility that it may be completed in time for a meeting of EU foreign ministers in Luxembourg on 23 June. Mr Younis said the advisory opinion last July of the International Court of Justice was clear and the EU had a moral, legal and political obligation to abide by the court's finding. "First, the occupation is illegal. It should be ended," he said. "Palestinians have full rights for self-determination. "What is really important [regarding] the advisory opinion is that it has obligations on third party states, and here we're talking about act not to prolong the occupation and to cease any cooperation with the state of Israel that would prolong the occupation. Mr Younis said the statements by religious right ministers in the Israeli coalition amounted to the ethnic cleansing of Gaza and that the time was ripe for the EU to apply concrete measures which would help bring about a two-state solution. "If Europe is still advocating the two-state solution, then they should say clearly that settlements are illegal and genocide [has] be stopped, and that Gaza is for Gazans," he said. Mr Younis accused Israel of deliberately frustrating the two-state solution by expanding illegal settlements in the West Bank and by creating irreversible facts on the ground. The Al Mezan Center for Human Rights is an independent, non-partisan, organisation based in Gaza.
