SCEPTREplus Trials

SCEPTREplus Trials

Fifteen new priorities have been selected for the second year of AHDB’s crop protection programme, SCEPTREplus.


Trials will investigate the effects of plant protection products and soil disinfestation techniques to control the potentially damaging disease, lettuce Fusarium wilt, which was confirmed in the UK for the first time in October 2017.


Following consultation with industry, other new priority targets include: capsids, bean seed fly, southern green stink bug, plum rust and celery septoria; along with a range of weed control trials on crops including Brassicas, onions, field-grown cut flowers and blackcurrant.


Work will also continue on some of last year’s trials, where promising results have been identified and further research is needed in order to expand the understanding of the products, including further efficacy and crop selectivity data.


The trial priorities for each horticultural sector can be found here: 


An update on the progress of SCEPTREplus in the first two years was given at the AHDB Agronomy Conference. Read the technical presentation from the Agronomy Conference here. 

Growers are encouraged to contact the project team to discuss and inform all trial priorities within SCEPTREplus. Contact joe.martin@ahdb.org.uk.

About the trials

All trials will be carried out to following ORETO standards. Once products have been tested for efficacy and crop safety, the results will be able to be used to support approvals where appropriate and link in with the EAMU programme to generate new approvals.


Where appropriate, we will again be taking a model crop approach to trials, then extrapolating on to other crops. This is to improve efficiencies and to make sure each crop sector is getting the most value from SCEPTREplus. 


SCEPTREplus will work closely with other research trials being funded by AHDB and other industry research to ensure that the trials being undertaken are building on and sharing existing knowledge. This will ensure there is no duplication of research and to maximise the value of the SCEPTREplus project. The results from the biopescticide trials within AMBER and the extensive AHDB fruit research programmes will be of particular value to SCEPTREplus.
