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

“The pesticide programs with the highest probability of being profitable for white mold management were Cobra at R1, Cobra at V4/V5, Endura at R3, and Delaro Complete at R3 across varying levels of [disease].... Although the average yield increase associated with Cobra in the meta-analysis was relatively modest, its lower cost and moderate white mold control resulted in a high likelihood of positive net return.” From the updated publication "Pesticide Impact on White Mold and Soybean Yield" at cropprotectionnetwork.org/publications/p… by @hoperbecton @MartinChilvers1 @dsmuelle @badgercropdoc @DTelenko @BisonBeanDoc +more @SoyResearchInfo @WISoyCheckoff @MichiganSoybean @IowaSoybeans @INSoybean @NDSUExtension @NDAgExpStation @ILSoybean #soybeans #USSoy
