Scoping review: impact of fungicide programmes on cereal and oilseed varietal performance



Contract Title:

Scoping review: impact of fungicide programmes on cereal and oilseed varietal performance

Contract Reference:


Contract period:

02/01/2024 – 31/03/2024



 1. Introduction

The AHDB Recommended Lists for cereals and oilseeds (RL) publications and resources provide information on yield and quality performance, disease resistance and agronomic features as well as market options to assist with variety selection.  The project is managed by AHDB and produced in collaboration with the British Society of Plant Breeders, United Kingdom Flour Millers and the Maltsters Association of Great Britain. 


Each year tests and trials are commissioned to provide robust data to allow selection of the best varieties which have a balance of features which are sufficiently better than existing varieties.  Currently information is provided for 11 crops, as detailed below.




Winter wheat

Winter triticale

Spring wheat

Winter rye

Winter barley

Spring oilseed rape

Spring barley

Spring Linseed

Winter oats


Spring oats


Winter oilseed rape



For most crops treated, yielded trials are done using full fungicide programmes which are designed to minimise disease.  Data resulting from these trials shows the genetic potential of a variety.  Trials that do not receive fungicide inputs, but do receive PGRs and other inputs according to best local practice, are also done to provide “untreated” yield data.  Information on resistance to specific diseases is provided as 1-9 ratings alongside yield data.

 2. Background / Aims

In November 2022 AHDB launched a review of the RL project.  Review activities included a questionnaire, focus groups and stakeholder interviews.  Results of this activity have shown that there is demand for information on varietal performance with lower or more commercially typical inputs, this includes fungicides.   


As individual farms face different challenges it is unlikely that it will be possible to determine a ‘typical’ commercial fungicide programme for the UK. 


AHDB is seeking to commission a high-level review that will provide an overview on the evidence for any significant changes to cereals and oilseed varietal performance when trialled with different fungicide programmes.


Examples of work in this area include:

Combining agronomy, variety and chemistry to maintain control of septoria tritici in wheat | AHDB

Fungicide performance in cereals and oilseed rape | AHDB


The results of this high-level review will be used to help guide decisions on how levy payer demand for information on variety performance with lower inputs will be met.


 3. Service Requirement

 a. Provide an assessment on varietal performance of cereal and oilseed varieties under different commercially relevant fungicide programs:

      a.Evidence to show how the rank order of varieties in trial, by fungicide treated yield, is impacted by fungicide rate, product choice and number of applications.

      b. Evidence to show how grain quality characteristics are impacted by fungicide rate, product choice and number of applications. This should include specific weight, Hagberg falling number, protein content and oil content, as appropriate.

      c. An overview of appropriate variety trial design, methodologies and data analysis/modelling to assess performance under different fungicide programmes that is practicable for use within a national trials system.


b. For each of the areas above an evaluation of the strength of evidence should be provided, this should consider:

     a.The robustness of the available evidence base.

     b.The context under which evidence has been obtained, for example laboratory research, field trials and/or on-farm practice.

     c. An assessment of how much confidence we should place in the conclusions reached.


c. Outline where there are gaps in evidence that AHDB may seek to address through the commissioning of future research.


In addition to providing this overall picture, the supplier should – where possible – also provide AHDB with supporting information about:


     a. How recently the evidence was published and an assessment of its quality. A separate spreadsheet should be provided as a bibliography and include web links, if used (this should be in addition to the reference list in the final report).

     b. Upcoming pieces of relevant research – e.g. UKRI-funded research projects and when they’re due to report.

     c. Where – UK/EU/other – the research was undertaken, drawing the boundaries of the search parameters to include only research from climates and locations that will resonate with UK farming practice.

     d. Whether there are any limitations – commercial sponsorship, patents etc – on AHDB’s ability to access the evidence.

     e. A broad assessment of the ‘academic/grey’ split in the evidence – and, alongside that, any attempt to give a sense of proxy measures for the quality of the evidence.


With this information AHDB will consider how information on varietal performance with lower fungicide inputs can be delivered.  This may be achieved through changes to the Recommended List, or outside of the RL through other related activities.  Results of this scoping review will be used by AHDB in direct communication with RL stakeholders, including farmers and processors.


AHDB will arrange a meeting for the selected supplier to present their findings.


A report will be submitted within 3 months of the project’s start date.

All bids will be scored against the criteria shown in the table below.  The selection will be an open and fair competition according to AHDB’s procurement policy, which complies with EU state aid rules.


Quality and relevance of proposal

Scope of the work and value for money

Experience and expertise of bidder


No response is provided or the response fails to answer the RFQ


No response or price not clearly linked to milestones, activity, or resource


No relevant experience for this tender, or no evidence provided


The response significantly fails to meet the standards required, it contains significant shortcomings and/or is inconsistent with other bids


The response contains significant shortcomings, and it is very inconsistent with the other bids


The response contains significant shortcomings relative to other bids, and CVs lack evidence of sufficient expertise or experience by bidding team


The response falls short of achieving the expected standard in a number of identifiable respects


The bid falls short and it is not clear how the costs and resources available will deliver the project


The bid falls short, with poor fit for the elements of the team that will deliver this work. Over-reliance on one or two key people to providing oversight and ensuring the contracted outcomes are met


The response partially meets the requirement and provides certain relevant information, but is lacking or inconsistent in material respects


The response meets some of the bid requirements, but there are risks, or additional costs that may materially risk the project being delivered as planned


Some experience of delivering this type of work. However, the team lacks sufficient support/experience at all levels. Over-reliance on early career expertise to deliver the project, with insufficient oversight, or time dedicated by more experience team members.


The response meets the requirement in most respects, but is lacking or inconsistent in some minor respects


The response meets the majority of the requirements, but there are some minor delivery risks or inconsistencies linked to the project, that may not materially impact planned delivery


A strong mix of support with relevant experience, a good track record of peer reviewed work, but weak evidence that this work has been converted from research to commercial reality. May have some IP/Products/Services that could be relevant to the project


The response meets the requirement in all material respects and is extremely likely to deliver the required output/outcome. Plus it contains a number of innovative solutions/outcomes


The response meets all the requirements, has a clear and transparent costs, which are reasonable and necessary


A strong mix of support with relevant experience, a good track record of peer reviewed work, and work that has been converted from research to commercial reality. In addition, the organisation brings with it additional IP/Products/Services that will enhance this project
