A quantifiable rating scale based on disease severity was developed for frogeye leaf spot (FLS) using image analysis software. The scale may be useful for estimating FLS severity in producer fields, which may aid in management decisions. Other applications of the scale include quantifying FLS severity in cultivar evaluations and foliar fungicide efficacy trials. Accepted for publication 17 February 2016. Published 22 February 2016.
Northern corn leaf blight (NCLB) is an annual issue for corn producers throughout the United States. Consequently, researchers are constantly evaluating hybrids for resistance and fungicides for efficacy. In most cases, NCLB severity is evaluated by visually estimating the percentage of affected foliage. Perceptions of disease severity are variable among stakeholders; therefore, a rating scale was created using photo analysis software that may be used to increase accuracy of disease severity estimations.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
