Potato Cyst Nematodes reduced with Caliente Mustard

Posted Apr 18 2011 1:37pm

Caliente mustard reduces root invasion from potato cyst nematodes.

The mustard should be sown, on the ground which is going to grow the potatoes, in the early autumn before the potatoes are to be planted.  The mustard is chopped up and incorporated into the soil in the spring, before potato planting.

Caliente mustard releases a gas called isothiocyanate  when it is chopped or crushed in damp conditions.  This gas acts as a biofumigant in the soil, and reduces the actions of  potato cyst eelworm.
