Serval yellow mustard is a popular, fast-growing green manure with a good ground cover. Due to the very fast establishment, Serval can be sown relatively late in autumn, where it still gives a rapid ground cover and a good weed suppression. The crop is susceptible to frost and freezes off in winter.
Serval is resistant to white and yellow beet cyst nematode (Heterodera schachtii and betae) at the BCA-2 level, this implies that a reduction of 70 to 90% of the nematode population is possible.
When SERVAL is in early flower stage, the crop can be chopped down and worked into the top soil. The chopped up crop will release glucosinolates which act as a biofumigant to kill nematodes, insects and even weed seeds. Best method is to chop, work into moist soil and pack all in one pass over the field. When properly managed, this will have the same effect on nematodes as a chemical fumigation, at a fraction of the cost.
