How can Integrated Pest Management & Integrated Farm Management strategies make a viable difference? 

With ever increasing pressures and legal regulations being placed upon the armoury within our chemical tool boxes and the farming economics, we will have to place more emphasis on Integrated Pest and Farm Management Strategies in order to help resolve these issues. Therefore, at this event you will get the chance to understand what these popular terminologies mean. Hear about current Integrated Pest Management research and the possible alternative pest control strategies that could increase the future viable protection of your crops.


  • Dr Sacha White specialises in developing integrated pest management programmes (IPM) for arable pests. A focus of his work at ADAS in recent years has been on cabbage stem flea beetle (CSFB), having led projects investigating control methods, larval population surveys for AHDB and monitoring the impact of the 2015 neonicotinoid derogation in winter oilseed rape. He is currently working an AHDB-funded three-year IPM project looking at improving control of CSFB, which includes investigations into crop tolerance, varietal resistance, agronomic risk factors, pest predictions methods and non-chemical control options for the pest. He has presented at numerous grower and agronomist events and scientific conferences, and contributed to several publications, including AHDB’s ‘Encyclopedia of pests and natural enemies in field crops’.
  • Andy Barr who many will know through his regular farming up-dates in the Farmers Weekly, farms at East Lenham in Kent. He moved to a no-till strategy in 2010 introducing cover crops on the farm together with, integrating companion crops with wheat and oilseed rape. After stopping using foliar insecticides some 12 years or so ago, he has been trialling a decreased fungicide regime i.e. using resistant crop varieties, varietal mixes in wheat and oilseed rape, and experimenting with crop competition. He has been reintegrating livestock (sheep), bringing grass back into the rotation, rotational grazing cover crops, and cultivating herbal leys; increasing the diversity in the grass. His farming ethos is to reduce chemical inputs, through a systems approach; combining different feasible, practical techniques.
