The harvested acreage and yield production data used in this report are from the Small Grains Summaries developed by the National Agricultural Statistics Service, USDA. Loss data are a summary of estimates made by personnel of the state departments of agriculture; university extension and research projects; Agricultural Research Service, USDA; and the Cereal Disease Laboratory. Please be aware the estimates provided by cooperators may be developed using different methodologies.
Losses (in bushels) were calculated for each rust as follows:
Loss (specific rust) = (Production) X (Percent loss)/(100%) - (Percent loss due to rusts)
Losses are indicated as a trace when the disease was present in commercial fields but losses statewide were less than 1%. Trace amounts were not included in the calculation of totals and averages.
