The warm weather of the past week has caused symptoms to fade of wheat spindle streak and soil borne mosaic. Wheat streak mosaic symptoms will become more pronounced with new growth and warmer temperatures. The first report of sorghum ergot by Claviceps africana was made this past week. The report is subject to official verification by taxonomists but appears to be correct. The field was one of the few which escaped the frost then bloomed.
Infection is thought to have occurred three weeks ago during flowering.
Symptoms included honeydew which was dripping onto the leaves. Action or comment by Texas Department of Agriculture and United States Department of Agriculture officials was not available at the time of this report. Wheat was beginning to joint in some areas. These reports were trace in Wichita and Greeley counties of overwintering rust. Speckled leaf blotch had some reports this past week.
