Abstract

Soybean (Glycine max [L.] Merrill) yield losses as a result of plant diseases were estimated by university and government plant pathologists in 29 soybean producing states in the United States and in Ontario, Canada, from 2015 through 2019. In general, the estimated losses that resulted from each of 28 plant diseases or pathogens varied by state or province as well as year. Soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) caused more than twice as much loss as any other disease during the survey period. Seedling diseases (caused by various pathogens), Sclerotinia stem rot (white mold) (caused by Sclerotinia sclerotiorum [Lib.] de Bary), and sudden death syndrome (caused by Fusarium virguliforme O'Donnell & T. Aoki) caused the next greatest yield losses, in descending order. Following SCN, the most damaging diseases in the northern United States and Ontario differed from those in the southern United States. The estimated mean economic loss from all soybean diseases, averaged across the United States and Ontario, Canada was US$45 per acre (US$111 per hectare). The outcome from the current survey will provide pertinent information regarding the important soybean diseases and their overall severity in the soybean crop and help guide future research and Extension efforts on managing soybean diseases.

Bibliographical note

Funding Information:
Support and funding were obtained from the United Soybean Board and the Crop Protection Network to aid in compiling the disease loss estimates. Ontario participation was supported by the Grain Farmers of Ontario, who obtained funding, in part, through “Growing Forward 2” (GF2), a federal-provincial-territorial initiative. The Agricultural Adaptation Council assists in the delivery of GF2 in Ontario. Thanks are also extended to individual state commodity boards for their financial support. Special thanks to the many people and agribusinesses that supplied information to help inform the disease loss estimates made by members of the North Central Extension and Research Activity 137 and the Southern Soybean Disease Workers. This manuscript is published in memory of Dr. Stephen Koenning, who, along with Dr. Allen Wrather, initiated this project many years ago.
