Information Sources for Soybean Pest and Weed Management
From now forward into the soybean growing season, management and/or control of soybean diseases, insects, and weeds is most critical.
Proper management of pests and weeds in soybeans requires access to complete and up-to-date information so that advance planning can be done. Links to much of this information are contained in postings throughout this website. The following compilation of some of the more important links will allow quick access to pertinent information.
DISEASES
A Soybean Disease Atlas provides pictures of disease symptoms, plus a written description of symptoms and management options. Information about Taproot Decline (TRD), a recently-identified disease of soybean, can be found here and here.
A fungicide classification chart that provides the mode of action of fungicides that are available for soybean disease control is provided by USB’s TakeAction resistance management program.

PEST CONTROL GUIDES
Up-to-date Disease, Insect, and Weed Control Guides for soybeans grown in the Midsouth states can be accessed here.
Click here for a combined Disease and Insect Identification and Control Guide from the Univ. of Tennessee.
IN-SEASON STATUS OF PEST INFESTATIONS
A Soybean Scouting Guide on this website is a detailed reference that can be used for the identification of soybean diseases, insects, and weeds, as well as recommended management practices for their control.
Updates for pest infestations during the growing season in the Midsouth are provided by crop specialists and consultants in the Mississippi Crop Situation blog, the Arkansas Row Crops blog, the UT Crops News blog, and AgFax.com. Advisories and analyses provided on these sites can be used by producers to anticipate pest outbreaks, plan or adjust scouting schedules, and select proper control measures.
