Interpretive Summary:

Technical Abstract: Wheat stem rust was light in most of the U.S. in 1996 due to unfavorable weather and effective resistance in most wheat cultivars. Greatest yield losses to stem rust in wheat were 3 percent in Illinois and Indiana and 2 percent in Michigan and Wisconsin. Race TPMK was the predominant wheat stem rust east of the Rocky Mountains as it has been for the past 4 years. Wheat leaf rust caused little damage in the Great Plains, but leaf rust caused 12 percent yield loss in California and 2 percent losses in Florida, Louisiana, and Washington. Four new leaf rust races were identified, but race MBRL, which was most common in each of the last three years, remained predominant. Stripe rust was more prevalent than last year in the Pacific Northwest, but losses were limited by moderate to good levels of resistance in most wheat cultivars. Washington suffered 2 percent yield loss to stripe rust in 1996.
