Rome Ethredge reported in the Seminole Crop E News this week that cold has damaged a lot of Canola and Carinata in southwest Georgia. Temperatures got down to 18 degrees a week ago and he says now is a good time to assess the damage. If the frost got down to the growing point, then the plant is dead and will need to be replanted, but if it only got the upper leaves, the plant should survive and put out new leaves. The most susceptible plants were the smallest, late-planted ones and the plants in low-lying areas which experienced the coldest temperatures.
