Crop loss calculator updated with latest data at cropprotectionnetwork.org/yield-loss-cal… In 2025, farmers in the U.S. and Canada experienced estimated losses of: ✅ $5.3 billion from corn diseases ✅ $2.2 billion from corn insect pests ✅ $996 million from wheat diseases ✅ $211 million from cotton diseases ✅ $2.3 billions from soybean diseases @travisfaske @DominicDReisig @justinmcmechan @bick_emily @badgerbean @AlbertTenuta @Jocelynlsmith @KelseyFAndersen @baldpathologist @alabamaED @MPlumblee @MandyBish1 @badgercropdoc @MartinChilvers1 @ppp_trey @DTelenko @BisonBeanDoc @DylanMangel @febina_m @dsmuelle @BorisCamiletti @YuanZeng3 @OhBuggers @NationalCorn @TheCottonBoard @kmbiss @USWBSI #corn #soybean #wheat #cotton

Many pathogens cause corn seed decay and seedling blight. 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; seeds can be difficult to find if badly rotted. Postemergence damping off appears as yellowing and wilting; seedlings soon collapse leaving only dead leaves above the soil. Nodal roots may show the same decay symptoms as seminal roots and the mesocotyl. If the nodal root system escapes decay, the plant will survive; it may be stunted or recover fully. 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. Ask local Extension for more information. @alisonrISU @cropdoc08 @alabamaED @ppp_trey @travisfaske @DTelenko @MandyBish1 @tjcksn @MPlumblee @dsmuelle @YuanZeng3 @baldpathologist @bobkemerait @badgercropdoc @MartinChilvers1 @maddishires @NationalCorn @kscorn @MississippiCorn #plant26 #corn #agx #seeds #farming

Fusarium head blight is one of the most significant diseases affecting small grain production, with epidemics occurring at higher frequencies and over a larger area than in the past. Yield losses can exceed 50% if conditions favor disease; however, it poses a more significant threat to grain quality and animal and human health.

Disease reduced corn yield by nearly 1.3 billion bushels worth more than $5.2 billion USD in 2025. Southern rust caused the greatest losses, followed by tar spot and northern corn leaf blight.

"Most fungicides resulted in greater breakeven probabilities with increasing disease severity. The results emphasize that fungicide applications occurring at VT/R1 and when disease severity exceeds 5% are more likely to result in a positive economic gain."
