RD-2003-2961 Resistance to strobilurin fungicides in septoria disease of wheat - PhD
Field observations have recorded resistance to strobilurin fungicides in wheat powdery mildew and, more recently, Septoria tritici. If this trend continues, it brings into question the future usefulness of strobilurins in crop protection programmes.
RD-2004-2956 Improved Resistance to Septoria in Superior Varieties (IMPRESSIV).
Septoria tritici blotch has been consistently the major disease of wheat in Britain for more than a decade. It is the principal target for foliar fungicides but control with strobilurins has recently become much more difficult because of the emergence of resistance to these fungicides, while there is little flexibility in the timing of application of triazole fungicides. There is therefore an urgent need to increase the availability of wheat varieties which combine good resistance to septoria with excellent yield and quality.
RD-2004-2992 Towards a sustainable whole-farm approach to the control of Ergot (LK0962).
The overall aim of this project is to develop an integrated package of measures aimed at reducing the risk of ergot infection in wheat crops whilst retaining the environmental benefits of grass margins. A new project was added in 2006, RD-2006-3266 Ergot in spring barley.
RD-2004-3024 Impact and interactions of Ramularia collo cygni and oxidative stress in barley.
To determine the conditions in which different barley varieties are at greatest risk from Ramularia and abiotic leaf spots and advise HGCA members on ways to manage the risk.
RD-2004-3025 Appropriate doses network – up to date information on fungicide performance for wheat growers.
To provide growers with up to date information on fungicide activity against all economically important foliar diseases of winter wheat.
RD-2004-3026 Appropriate Fungicide Dose sequences and mixtures in winter wheat according to disease risk.
To establish the principles by which farmers will develop fungicide programmes and mixtures in winter wheat from Appropriate Fungicide Dose information.
RD-2004-3027 Appropriate fungicide doses on barley – production of dose response curves to advise growers on fungicide efficacy and potential resistance.
To provide barley growers with information on appropriate fungicide doses.
RD-2004-3028 Understanding fungicide mixtures to control Rhynchosporium in barley and minimise resistance shifts.
To study the contribution of individual fungicides to Rhynchosporium control in mixtures and to understand the impact of fungicide mixtures and sequences on Rhynchosporium sensitivity.
RD-2004-3128 Understanding evolution and selection of azole resistance mechanisms to septoria leaf blotch in the UK [LK0976]
To understand the genetic basis and evolution of resistance to azoles in the M. graminicola population and to use this knowledge to develop robust strategies to maintain the effectiveness of this important group of chemicals in crop protection.
RD-2004-3134 Monitoring risks of mycotoxin contamination caused by Fusarium head blight pathogens in winter wheat
To monitor and investigate fusarium disease and mycotoxin contamination in winter wheat and to advise industry of seasonal and regional risks.
RD-2005-3187 United Kingdom Ceral Pathogen Virulence Survey (UKCPVS), [cont. from RD-2002-2756]
To monitor changes in virulence of UK cereal pathogen populations and determine their significance for the resistances that are being used in current varieties and breeding programmes.
RD-2006-3288 Improving risk assessment to minimise fusarium mycotoxins in harvested wheat grain
Monitoring the fusarium mycotoxins deoxynivalenol (DON) and zearalenone (ZEAR) at harvest in UK wheat.
RD-2006-3332 Improving risk assessment to minimise fusarium mycotoxins in harvested oats
Project aims are the monitoring and modelling of fusarium mycotoxins deoxynivalenol (DON), HT2, T2 and zearalenone (ZEAR) at harvest in UK oats.
RD-2006-3333 Evaluation of Rapid Test Kits as Potential Screening Tools for Ochratoxin A (OTA) Determination in Wheat.
To identify potential commercially available methods/technologies for the quantitative assessment of OTA in cereals.
RD-2006-3334 Assessing take-all risk in second wheats
To compare and evaluate the molecular PCR based method for detecting take-all DNA in the soil as measured by a seedling bioassay, in the subsequent development of take-all in the following crop.
RD-2003-2726 Reduced fusarium ear blight and mycotoxins in UK wheat through improved resistance (REFAM, LK0932)
To identify and characterise both new and the best available sources of resistance to fusarium ear blight and toxin accumulation in wheat.
RD-2006-3374 Molecular quantification of air-borne pathogen inoculums to predict regional disease epidemic risk (BBSRC IPA)
To optimise efficiency and deployment of air sampling devices to provide warning of regional disease epidemic risk to aid crop-specific disease management decisions.
RD-2006-3397 Fungicide performance on winter wheat
To provide growers with independent information on the performance and use of existing and novel fungicides against the economically important foliar diseases of winter wheat.
RD-2007-3401 Improving risk assessment to minimise fusarium mycotoxins in harvested malting barley
Monitoring and modelling of fusarium mycotoxins deoxynivalenol (DON), HT2, T2 and zearalenone (ZEAR) in UK malting barley at harvest.
