Cold weather hampers Virginia corn planting

An early April cold snap may halt corn planting in Virginia and could cause problems for growers already well along in planting the 2007 crop.

Wade Thomason, Virginia Tech Extension gains specialist, says projected lows in the mid-30s and highs in the mid-50s are not conducive to corn germination.

Typically corn comes up in 5-7 days.

Corn that has emerged has a high risk of imbibing cold water, causing cell membrane eruption.

Corn planted and not emerged will tend to just sit there in the ground, exposing the crop to disease pathogens for a longer period of time.

Thomason suggests growers wait for a 6-8 day stretch of prolonged warm weather to plant corn in Virginia.
