Black scurf affects tubers' quality of presentation and can cause seedlings if the seed tuber or soil is infested. It is causing severe economic losses. Chemical control exists but is not 100% effective. Under the plan ECOPHYTO 2018, we are looking for new cropping systems that tend to reduce the use of pesticides at the expense of alternative products. Since 2006, in order to fight against this disease, we have tested various products such as plant defenses stimulators, antagonistic microorganisms, extracts of plants, animals and minerals. Some alternative products either alone or with a reduced dose of fungicide show encouraging results. Finally, tests biofumigation using mustard intercropping have been underway since 2009.
