Southern rust, tar spot & gray leaf spot = fungi. Bacterial leaf streak & Goss's wilt = bacteria. Properly ID & assess risk for best disease management outcomes. Ask local Extension for more info. @DTelenko @alisonrISU @baldpathologist @MahDuffeck @maddishires @MandyBish1…
#Corn kernels near the tip often fail. Ears prioritize their lower portion and set kernels by 20 days after tassel. Thus, kernels often abort when energy is limiting. Reasons may include: 🌽Saturated soil ✔️Cloudy days 🌽Nutrient deficiencies ✔️Genetics 🌽Variable growth
Here are reminders of what Southern rust looks like and what to expect. Send samples to @UNLPlantClinic @UNLExtension @UNL_CropWatch

Because I’m walking plots today…..be mindful, there is plenty of “poop spot” (the black spots in the pics) on corn this year in MS. Two things to know: 1) this isn’t tar spot, and 2) fungicides don’t protect you from poop spot #mscrops

With diseases starting to pop up, a quick reminder that some of those popular disease prediction apps (Tarspotter and Sporecaster) are no longer active. These models have been move to the Crop Protection Network. cropprotectionnetwork.org/crop-disease-f… @CropNetwork
🎥Deciding when to terminate irrigation starts by estimating #corn maturity. We do this by evaluating kernel milk-line progress as hard starch develops after dent. #mscorn #mscrops #MSUext (Erick Larson, MSU Extension grain crops specialist)

Fusarium head blight (FHB) reduces wheat yield and quality and can result in toxin contaminated grain. A properly adjusted combine can help reduce scabby kernels in harvested grain. Combine fan speed adjustment can help remove moldy and lightweight kernels and reduce toxin…
Dent corn fungicide trial applied this afternoon. 13 different treatments (with the check). Some great Curvularia leaf spot already present, and a little southern rust @MississippiCorn @MStateCorn #mscrops

NEMATODE MONDAY: Something special (NOT good) about digging up a root system infected w/tRoot-knot nematode. Symptoms of most plant-parasitic nematodes are just not as dramatic. The galling disrupts the plants normal function leading to stunted unthrifty plants #Nematology #SON
