Biosterelant Mustard seed ?

I use victoriana nurseries a lot, and have done so for a few years now. I always find their stuff reliable, and the plants have always been strong and healthy.
I have planted bio-sterilant mustard, as I have eelworm.  I looked it up first on Google, which recommended it as an organic method of getting rid of them,then found Victoriana was the only place I could buy it.
I have sown it on one of the new beds, which haven't been cultivated for 20 or more years, as I want to put potatoes in next year.
I will let you know if there is any improvement on the crop next year.
The only problem I can see is that you have to dig the flowers in within one hour of cutting them, so will have to work like a steam roller when the time comes.

I was googling about some brassica problem and came accros a few articles relating to this topic.  Apparently, all brassica foliage will sterilise the soil to some extent, most effective being mustard and Indian/green mustard at that.

Kings is £9.75 for 2.5 kg white mustard seed to cover 850 sq m.

Also Asian supis sell very cheap mustard seed.
