Updated information on fungicide efficacy 🌽 🫛 🌾

Many pathogens cause seed decay and seedling blight in corn. The first symptom may be an area of the field with poor or no stand. Decayed seeds are very soft and may be covered with fuzzy fungal growth. Post emergence damping off appears as yellowing and wilted seedlings that soon collapse leaving only dead leaves above the soil. Favored by cool, wet soils, these diseases are more common in low-lying or poorly drained areas or in fields planted too early in spring. Standard seed treatment fungicides reduce risk. Planting when the soil is above 50°F and soil moisture is not excessive also may reduce risk. Ask local Extension for more information. @baldpathologist @alisonrISU @tjcksn @cropdoc08 @DTelenko @badgercropdoc @MartinChilvers1 @ppp_trey @travisfaske @YuanZeng3 @alabamaED @MandyBish1 @maddishires #plant26 #corn #grow26

@itsAmit_Sharma @badgerbean @badgercropdoc Congratulations 🎈🎊🍾🎉

Excited to win 🥇1st place at the Southern Soybean Disease Workers Annual Meeting in Pensacola, FL Grateful to @badgercropdoc, Carol Groves and @badgerbean for their support. Also honored to receive the Thomas L. German Student Support Award from Department of Plant Pathology.

Need something to watch on this ghastly weather day?

D. Mueller of ISU received the Communications Award 🥇 from the Alabama Assoc. of County AG Agents. He was honored along w/t A. Sisson (Sebastian Bartholomew) for the phytopoetry book “It’s Still Edible” released by the Crop Protection Network @phytopoetry @CropNetwork @ISU_IPM

@WestTexasIPM Thanks for the info, @WestTexasIPM! There is also a recent CPN TV episode on Managing Cotton Jassid at youtu.be/liREK5nlJKI from @ScottGraham72 and Isaac Esquivel. #cotton @CottonInc

Septoria brown spot, one of the most common soybean diseases in MS especially in continuous soybean fields. Normally, brown spot stays in the lower canopy. Rarely do fields need a fungicide. Cooler than normal temps and heavy dews have made it look worse this year #mscrops

Charcoal rot is the main disease reducing soybean yield in Oklahoma Drought conditions during the growing season favors the development

Southern rust affects double-crop corn in Oklahoma every year! Corn growers, stay alert for possible corn yield losses due to diseases 🌽

“Accurate diagnosis of [soybean vein necrosis virus] is important because it can be easily confused with other soybean diseases, disorders, or damage, potentially leading to unnecessary fungicide applications.” From the updated publication An Overview of Soybean Vein Necrosis Virus at cropprotectionnetwork.org/publications/a… by @badgercropdoc @cropdisease @MartinChilvers1 @dsmuelle @AOV_OlmedoVelar @alabamaED @AlbertTenuta @cropdoc08 +more @baldpathologist @MandyBish1 @MahDuffeck @travisfaske @ppp_trey @maddishires @DTelenko @BisonBeanDoc #soybeans #thrips #virus #USSoy

Updated information on yield losses caused by diseases in cotton in 2025 growing season

“Management of charcoal rot includes the use of resistant varieties when available and certain cultural practices, including those that conserve soil moisture. No fungicide seed treatments have been identified that offer consistent control of charcoal rot.” From the updated publication An Overview of Charcoal Rot at cropprotectionnetwork.org/publications/a… by @badgercropdoc @MartinChilvers1 @NCLegumeLady @dsmuelle @maddishires @BisonBeanDoc and @cropdoc08. @baldpathologist @MandyBish1 @MahDuffeck @travisfaske @ppp_trey @DTelenko @AlbertTenuta #soybeans #fungi #USSoy

Fusarium head blight (FHB) is a devastating disease of wheat. R. Debacker Moura et al. present an evaluation of single and two sequential fungicide applications during flowering for FHB management in winter wheat in Kansas: doi.org/10.1094/PHP-06… @KSUPlantDr

“Chemical management strategies do not result in complete control of white mold and, therefore, should be considered only as one component of an integrated management program. Reduction of white mold incidence achieved by fungicides in university field trials has ranged from zero to approximately 60%.” From the updated publication An Overview of White Mold at cropprotectionnetwork.org/publications/a… by @badgercropdoc @cropdisease @MartinChilvers1 @travisfaske @DylanMangel @dsmuelle @ISU_IPM @BisonBeanDoc @cropdoc08 +more @AlbertTenuta @baldpathologist @MandyBish1 @MahDuffeck @maddishires @DTelenko #soybeans #USSoy
