What are ISUs management suggestions?
“The only management suggestion at the moment is to wait a week or so to see what the damage is,” says Barnhart. He offers these guidelines. New seedings – Seedlings that were frozen so that all trifoliate leaves are discolored and dying will not regrow. If new seedings were permanently damaged, consider reseeding as soon as possible. Keep the good areas and drill into thin or damaged areas. Tillage may not be necessary. If you think that a cereal grain companion crop, still present, will be too competitive or will impede the reseeding, then tillage may be required. Established stands – If regrowth shows frost/freeze damage, wait a week to 10 days then dig some random plants. Check whether remaining crown buds are still firm and intact. Split the taproots. Healthy taproots are creamy-white in color, with a firm texture. Freeze-injured taproots will begin to be watery, tan/brown in color and beginning to soften. If cold injury to established stands was light, only affecting some of the
