The stem will eventually collapse so completely that the plant falls over. A study designed to look at transplant plug moisture levels in the field proved fruitless as heat girdling occurred in all treatments regardless of plug moisture levels. However, we realized that efforts to establish the treatments had taken so long everything was transplanted between 11a.m. and noon. As a result, another trial was established to test the effect of planting time on the incidence of heat girdling. Your production schedule may not allow you to discontinue planting from 11 a.m. to noon for example, but if you do, we believe your need for resets will be reduced.
Weather plays a dominant roll as well.
These studies will be repeated this month so, we will keep you posted.
