Small grain losses due to rust

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%.  Zeros indicate the disease was not reported in commercial fields in that state during the season.   Trace amounts were not included in the calculation of totals and averages.
