Query multiple types of production and estimated yield loss data by timeframe, disease, and geographic area*

Select desired start year and end year. For a single year of data choose the same year for both start and end.
Select a disease category, which will autofill the diseases.
Select one or multiple diseases.
Further define geographic area by country, region, or select one or multiple states.
Click on Search and results will display.
Further details are available by clicking on Production and Losses within results.
If specific diseases or states are not selected, the output will include values for all diseases and states present in the selection boxes.
NA means data not collected for that year and geographic location.

*Not all data categories are available for all locations and all years, and disease categories changed slightly as data collection progressed. Disease loss data was traditionally presented separately for the Northern U.S and Southern U.S., categories which differ from the states within regional IPM center groupings.

These data are expert estimates only.
Data is currently available from 2012 onwards.
Mycotoxin contamination values are currently unavailable.
Corn loss data are not available for Alabama from 2012-2018, Georgia from 2012-2019, Missouri in 2013, South Carolina from 2012-2019, and Virginia from 2012-2016.
Categories for Curvularia leaf spot and crown rot were added in 2022; however, detailed notes allowing for the separation of crown rot and stalk rot were not obtained in all states in 2022.
Inflation has NOT been accounted for in reported USD values.
