Herbicide injury, fertilizer injury, drought injury - lack of water during establishment.
Damage can vary from death within days of planting to only slight stunting. Cool moist conditions do not favor fumigant dissipation.
Damage may be more prevalent in wetter areas and heavier soils. During very wet years injury may be through entire field. Secondary infection on affected tissue may be present. Small areas of affected plants will be present where fumigation rig stops prior to turning off fumigant.
May be able to replant if problem is discovered shortly after planting and fumigant has dissipated. Punch holes 24 hours prior to plating if fumigant residue is detected to allow fumigant to escape. Plant a few test plants several days prior to planting entire field if in doubt.
Apply fumigant at proper rate. Allow extra time between application and planting if conditions are cool and wet. Fumigate earlier than minimal plant back date to allow for poor environmental conditions.
