Chloride significantly increased grain yield at both sites, although not all treatments increased yield. That means -it generally will readily leach out of the soil. Adding more than what the plant can use in a single season is not economical, because it probably won't be there for the next crop. Small amounts appear to be better than large amounts -10 pounds per acre. Not all varieties respond the same.
Key issue is variety and soil test.
If the levels are less than these, consider a 10 pound per acre application of any form of chloride. Pyrenophora triticei-repentis and the Septoria 'complex', including Septoria nodorum and S. triticei. Accurate diagnosis will be necessary but growers in high residue management may have a higher incidence of tan spot disease. Chloride will not control the disease but there may be an indirect effect on yield from the improved plant nutrition. On the other hand, expensive fungicide applications will not 'cure' the physiologic leaf spot, so once again an accurate diagnosis will pay big dividends.
