Full Title: Evaluation of the efficacy of biofumigant crops for management of potato cyst nematodes
Duration: March 2014 to October 2017
Collaboration: Harper Adams University, Barworth Agriculture, SRUC

Background

Biofumigation is a strategy which exploits plants, mainly belonging to the Brassica family, that produce compounds called glucosinolates. When the tissues of the plants are damaged glucosinolates are broken down and various volatile compounds, including isothiocyanates (ITCs), are released. ITCs have been shown to affect nematodes and their release is the basis of the biofumigation effect. A range of biofumigant crops are commercially available in GB and field trials have been completed to:

  • determine the potential of biofumigant crops in Northern and Southern Britain
  • optimise the incorporation of the biofumigants
  • determine the effect of different nitrogen and sulphur inputs on glucosinolate profiles and the impact on PCN populations.

The work has been carried out in parallel with the related project 114R478.

Aims and Approach

Aim: To determine the potential of biofumigant crops for the management of PCN. The field trials have been completed and analysis of plant samples (for glucosinolate content) from the trials is ongoing.
