Yield Loss Calculator
The purpose of these calculators are to share economically important information on estimated crop losses from diseases and insect pests. These calculators query multiple types of production and disease or insect pest yield loss data for a variety of user-defined factors. The loss values here are expert estimates and not actual loss values. The goal is to better inform industry agronomists, researchers, extension workers, commodity groups, and funding agencies about the impact of diseases and insect pests on corn, soybean, and wheat production in order to more effectively direct limited time and resources.
Severity Estimation Tool
Use this web tool to help train your eyes for more accurate disease and defoliation ratings on field crops. Crop scouts and researchers often overestimate the amount of disease severity or defoliation on leaves, and the activities here will help hone assessment skills for common crop diseases and insect pests.
