Named Vittasso brown mustard, the product is already popular in the US and some parts of Europe. It works as a biofumigant - meaning that it contains volatile, plant-derived chemicals that can suppress soil-borne pathogens, nem- atodes, insects and weeds - on potato, soft fruit and salad crops.
The plant is grown as a crop and then ploughed into the ground where it breaks down and releases isothiocyanates into the soil.
These isothiocyanates work in a similar way to other chemical fumigants, such as methyl bromide.
According to Boston Seeds, the product is best used as a green manure, potato disease suppressant or organic catch crop.
Boston Seeds representative Andrew Wallis said: "We are just beginning to advise the wider industry through contractors, packers and agronomists about the natural benefits of biofumigation. Initial response is very positive and I expect to see Vittasso being used extensively - especially by potato growers and organic farmers."
Vittasso costs £65/ha.
