Getting Started

Five Steps to Mighty Mustard® Success:

1. Determine your primary goal:

Do you want to suppress soilborne pathogens? Reduce nematodes? Suppress weeds?

2. Choose the Mighty Mustard® that targets your goal:

Picking the right primary glucosinolates makes all the difference. If suppression of nematodes and soilborne pathogens is your primary goal, choose Kodiak, Pacific Gold or Trifecta Power Blend. If weed suppression if your objective, choose White Gold.

3. Plant:

Time the seeding to ensure maximum biomass production, preferably in early spring or late fall. Mustards are day-length sensitive and will winter-kill at sustained temperatures of 26 degrees Fahrenheit or colder.

4. Chop and incorporate:

Chop, incorporate and irrigate in one day to ensure speedy release of short-lived glucosinolates into soil.

5. Rest:

Wait three weeks before planting next crop.

When done correctly, on-farm testing is a good way to evaluate green manures. However, a single side-by-side comparison, although easy to conduct, will not tell you if your observations were the result of the practices you were comparing or the result of other varying conditions.

For best results:

  • Start with a small part of a larger field
  • Leave areas that are managed as normal
  • Use replication and randomization
  • Call your local Extension office for help and resources to conduct on-farm tests
