I was wondering if there is any risk of bio mustard releasing substances that may work against the good fungi etc and inhibit the growth of my veggies in the following growing season? I know it has fantastic bio fumigant properties to work on nematodes etc; but is that all it affects in the soil? The plan is to clear out all the summer veggies and sow the bio mustard seed and then turn it back into the soil later in the season and then plant out agin for the Spring.

Thank you for contacting us regarding mustard seed. It has been scientifically proved effective for deterring nematodes, as the chemical glucosinolates released from the seeds is similar to synthetic commercial products. Some company claims their mustard seeds has been found to suppress many soil-borne fungal pathogen such as sclerotinia, Verticillium wilt, rhizoctonia, fusarium, and apahanamyces. You could read more from http://www.mightymustard.com/benefits. There is no evidence yet to indicate the chemical will work against beneficial soil fungi. Another commonly used companion plant is French Marigold (Tagetes patula), you could sow the seeds direct to soil and use as a bio pesticide. Please see more information Seeds Vegetables Hope this helps and happy gardening. Best Regards, Louise Yates Horticulturalist
