SOIL PREPARATION

DOUGLAS AG

Important information for maximum efficacy and safety.

Soil Preparation

  • Soil should be in good seedbed condition prior to fumigation.
  • Break up clods and loosen soil by cultivation one week before application.
  • Work soil deeper than intended fumigation.
  • Soil should be free of trash to prevent the "chimney effect" and to reduce fumigant "tie-up" in organic matter.

Soil Moisture

  • Adequate soil moisture should be available.
  • Soil capacity must be at a minimum 50% field capacity.
  • USDA Soil Moisture "Feel and Appearance Test".
  • DO NOT FUMIGATE DRY SOIL.
  • Apply at depth according to label.
  • Make sure the field is properly posted with appropriate signage.

Ensure Proper:

  • Soil preparation
  • Soil temperature
  • Soil moisture
  • Soil sealing
  • Application depth
  • Calibration, set-up, and maintenance of application equipment
  • Prevention of end row spillage
  • Soil must be left 10 - 14 days after application.
  • An unlicensed person may NOT re-enter the buffer zone 48 hours after application, and 5 days after the application in the fumigant block.
  • At end of fumigation period and prior to planting make sure there is no chloropicrin present.
  • Perform a lettuce seed test, or place transplants in field to test for residual fumigant.
