The first freeze of the season that hit Southwest Oklahoma earlier this week should have little if any effect on upcoming winter crops and grasses, according to an Oklahoma State University official.

Mark Gregory, area extension agronomy specialist of the OSU Southwest District area office in Duncan, reported that the Monday morning freeze came and went with virtually no effect on ground soils or upcoming winter crops to be grown in those soils.

"It won't have any effect on wheat planting," he said. "But it may have cut down the growth of summer grasses."

Gregory said one benefit of the loss of growth to summer grasses is less competition for other vegetation. "It will help winter grasses grow," he said.

One minor effect of the frost on fields could impact Johnson grass temporarily. "It might pose a minor problem for cattle grazing for the next week or so," Gregory said.
