Biofumigation Seed Mix – Root Knot Nematode Control Green Manure Seeds
Botanical Blend: Brassica spp. + Raphanus sativus
High Glucosinolate Brassica Blend for Natural Soil Disease Suppression
Our Biofumigation Seed Mix is a specialised green manure blend designed to help suppress root knot nematodes, reduce soil-borne diseases, and improve long-term soil health naturally. This carefully selected mix contains high glucosinolate brassica species chosen for their strong biofumigation performance, vigorous biomass production, and excellent soil improvement benefits.
When grown and incorporated into moist soil at early flowering, these brassicas release natural biofumigant compounds called glucosinolates. These compounds help reduce harmful nematodes, fungal pathogens, and pest pressure while improving soil biology, organic matter, and overall growing conditions for your next crop.
Ideal for vegetable growers, orchard preparation, peony and rose gardens, flower beds, regenerative farming systems, and crop rotations before planting sensitive crops such as tomatoes, carrots, brassicas, onions, roses, and peonies.

- Excellent for crop rotation, fallow periods, and orchard preparation
- Suitable for organic gardening and regenerative farming systems
What’s Inside?
A carefully balanced blend of proven biofumigation brassicas selected for maximum glucosinolate production, strong root development, and powerful soil cleansing action.
- Black Mustard (Brassica nigra) – High glucosinolate levels for strong nematode suppression and soil disease control
- Ethiopian Mustard (Brassica carinata) – Excellent biomass production with strong biofumigation performance and deep rooting
- Forage Rape (Brassica napus) – Fast-growing brassica with strong glucosinolate production and vigorous biomass accumulation
- Cappuccino Mustard (Brassica carinata) – Late flowering mustard with strong leafy growth and excellent soil conditioning benefits
- Biofumigation Radish Types (Raphanus sativus) – Deep taproots help relieve compaction and support broad nematode suppression
- High Glucosinolate Brassica Selections – Carefully chosen biofumigant brassica lines for enhanced disease suppression and stronger soil cleansing effects
Plant Details
- Plant Type: Cool-season annual biofumigation green manure mix
- Coverage: Approximately 1 kg per 400–500 m² depending on sowing method
- Best Use: Root knot nematode suppression, disease break crop, soil improvement, orchard preparation, flower bed preparation, and regenerative farming
Sowing Information
- Sow When:
Temperate: Late summer to autumn or early spring
Subtropical: Autumn to early spring
Tropical: Dry season and cooler months
Cool Regions: Late summer to early autumn - Germination: 5–10 days at 10–25°C
- Sowing Depth: 5–10 mm deep
- Position: Full sun preferred
- Sow Where: Broadcast evenly over prepared soil and lightly rake in
- Soil Type: Fertile, well-drained soil with moderate moisture
- Spacing: Broadcast evenly or sow in rows 20–30 cm apart
Management
- Water regularly during establishment for strong early growth
- Allow 6–8 weeks of vigorous vegetative growth before incorporation
- For maximum biofumigation effect, slash or mulch at early flowering
- Immediately incorporate green material into moist soil
- Seal moisture with irrigation if conditions are dry to improve fumigation effect
- Wait 2–4 weeks before planting the next crop
Harvest and Incorporation
For best results, chop and dig in the crop at early flowering when glucosinolate levels are highest. Immediate incorporation is critical to maximise the release of natural fumigant compounds into the soil profile. This process is especially effective for reducing root knot nematodes before planting roses, peonies, tomatoes, carrots, onions, brassicas, and other susceptible crops.
When to Sow Biofumigation Mix in Your Climate
| Climate Zone | Best Planting Time | Growing Tips |
|---|---|---|
| Temperate | February–April or August–October | Ideal after summer crops or before spring vegetable planting |
| Subtropical | March–July | Best during cooler months; avoid peak summer heat |
| Tropical | April–July | Use during the dry season for strongest establishment |
| Cool | Late summer–early autumn | Excellent after harvesting summer vegetables; tolerates light frost |
| Arid | March–May | Use irrigation and mulch for strong early establishment |
