Is it dead?
Chaotic winter weather can wreak havoc on your winter forage. In most cases, as long as the bottom portion of the tiller is still healthy the crop will still survive. If the plant is exposed to this type of freeze incident after the jointing stage? It is more likely that this crop would not survive. In all these examples the crop is still in the vegetative stage.
Freezing damage on your winter forage.
Complete Tiller Death. The crown may still be viable but expect a complete loss.
Normal Survival
Normal Survival shows good green spring growth.
Browning
Browning is present from the middle of the leaf extending towards the tip. The browning area will dye and drop from the plant. Extremely dark leaf areas (water-soaked look) will also die and sluff from the plant. But in this case the lower portion of the tiller is still health.
Growing out of damage.
This is what the crop will look like as it drops dead tissue and begins to grow out of the damage. Looking for an assessment of your field, your local TriCal Associate would love to help.
