Weed control snapshots

Weed control snapshots

Early season rains kept many growers out of the fields pushing planting dates much later than normal. The rains also delayed weed control applications in some regions of the Cotton Belt. Rain makes weeds grow as well as cotton, making delayed layby applications particular important.
