Frost and/or freeze damage will be evident several days after a frost event and will result in a brown-purple water-soaked appearance on the hypocotyl and cotyledon. Soil crusting may slow or prevent seedling emergence causing the seedling to die before emergence.
Environmental issues can be exacerbated by non-uniform planting depth and/or seed spacing in addition to incomplete closure of the seed furrow. This would result in a gap in the row where seedlings may be absent or only partially emerged.
- Plant after risk of freeze/frost passes
- Calibrate planter for each field and regularly check that the furrow is being closed. Adjust planter as needed for optimal planting depth and density.
