Brown Mustard

(Brassica juncea)

  • Natural bio-fumigant of root-knot nematode
  • Reduces soil crusting
  • Improves soil infiltration
  • Increases organic matter and the subsequent increase in beneficial microflora and microfauna
  • Reduces effects of bacterial wilt on successive vegetable crops
  • High pollinator value

Scala has been selected for bio fumigation. After the bruising and processing of the crop, the active substances are converted into gases that are toxic to a large number of soil organisms. Bio fumigation is mainly aimed at combating soil fungi, such as brown rot in potatoes. Seed should be sown in very early spring for spring use and in the autumn for winter use.


Brown mustard requires a good sandy loamy soil, with adequate N; P; K; S to ensure rapid establishment. This crop should not follow other Brassica crops in rotation. For disease control, it is best grown once every 3–4 years.
