Rotty ‘Gibs: A Haiku Gibberella rot Pink mold and mycotoxins Vestige of an ear
Relentlessly wet and dewy weather ahead of harvest has been resulting in more ear rots than I would like to see. Keep an eye on fields, consider harvesting for direct ship instead of risking storage. Fusarium and Gibberella are the main culprits.

High moisture wheat will generate heat, which promotes the development of mould and insects and can impact the end-use quality of grain. Learn more about the risks of adding water to grain: https://t.co/byFd9OT6xP

Stalk decay in corn Beware the wind as pith rots Broken hearts and stalks Haiku for all the corn feeling down out there...
Severe foliar disease can weaken corn stalks. Test stalks using the pinch test and prioritize harvest for that field if 10 percent or more stalk rot. Ask local Extension for more info. @alisonrISU @DTelenko @MandyBish1 @maddishires @MartinChilvers1 @badgercropdoc @tjcksn

New to scouting for verticillium stripe in #canola? The disease is easiest to identify just prior to or just after harvest when symptoms are most obvious. Learn more about identifying verticillium stripe in @CanolaWatch: https://t.co/gkcFyxUQgX

Scouting is similar for all corn ear rots. Starting at late dent stage (R5), choose 20 ears from 5 areas in the field. Pull back the husk to see the entire ear. It's critical to identify ear rots in the field as several ear rot fungi produce mycotoxins, which can harm livestock

Moisture map reveals risks... Surface moisture levels at field capacity are needed for the germination of sclerotia. The @pcdmn has been working with @AAFC_Canada to obtain maps showing soil moisture based on satellite observations. The organizations' findings ⤵️ #WestCdnAg

🚨 Canola Bloom = Time to Scout for Sclerotinia Risk ✅ Check soil & canopy moisture ✅ Scout for apothecia in fields with dense canopies ✅ Monitor conditions daily — moisture + bloom = critical window ✅ Base fungicide decisions on crop stage, canopy wetness & pathogen
