N Field Observations

Sudden Death Syndrome (SDS) is showing up across Nebraska. Dylan explains how cool, wet weather triggered it, key symptoms to spot, and how to manage it next season with resistant varieties and #seedtreatments. 🌱 #Soybeans #SDS #CropDisease

🚨 Sudden Death Syndrome (SDS) is starting to show up in soybean fields. 🔍 How to identify SDS: * Yellowing between leaf veins while veins stay green * Leaf tissue may turn brown & die, but veins remain visible * Roots often show rot & deterioration ⚠️ Reminder: SDS infections occurred this spring, so there are no treatment options at this stage. Management decisions will need to focus on future seasons. #Soybeans #CropScouting #PlantHealth #NFieldObs @DylanMangel @UNL_CropWatch @holtboyd @UNLExtension

Talon Mues, a UNL Extension WICS Instructor, shares quick tips for identifying tar spot in your corn. #NebExt #NFieldObs #PlantDisease #CropScouting #CropManagement

White Mold is showing up in #soybeans across #Nebraska. Watch here to see the symptoms and learn what you can do about it. #nfieldobs #whitemold #disease @DylanMangel

There's a few options for annual forages and cover crops in drought. We return to our demo plot at Middle Niobrara NRD in Valentine for a quick update! @NebraskaNRDs #CoverCrops #Forage #NFieldObs #NebExt #UNLExt

Hail damage at V4-V5 = bruised stalks, potential entry for rot later. 📅 Flag these fields for a September check to prioritize harvest & avoid lodged corn. @tjksn @UNL_Cropwatch @CropNetwork #HailKnow #NebExt #NFieldObs #CornWatch #HailDamage #HarvestPlanning #AgTwitter

🚨 Corn hail at V4-V5 can open the door for bacterial diseases to infect through wounds. Keep an eye out—fungicides won’t help here. Scout often, stay alert. 🌽⚠️ @tjcksn @UNL_CropWatch @CropNetwork #NebExt #NFieldObs #HailKnow #CornDiseases

#Marestail is tough to control post-emergence in #soybeans—many populations resist #glyphosate. Choose #herbicides based on the resistant soybean variety you plant. Limited options mean planning matters. @AmitUNL @MarthaMamo3 @unlagrohort @UNLExtension #WeedControl

🚨 Tar spot showing up on V6-V7 corn! Don’t rush fungicides—research shows VT–R3 is the best time to treat. 🌽🦠@tjcksn @CropNetwork @UNL_CropWatch #NFieldObs #NEBEXT

👖Properly washing clothes after #pesticide use is key to safety! 🫧Wash separately, use hot water & run the washer empty when done. #NFieldObs #NebExt

🌾 Fall-planted #cerealrye suppresses winter weeds + Palmer amaranth (if terminated after corn planting). Split N apps = stronger corn emergence: at planting + ~3 weeks later. @AmitUNL @MarthaMamo3 @unlagrohort @UNLExtension #CoverCrops #Corn #NebExt #NFieldObs

Alfalfa #weevils are a key pest of #alfalfa, especially before and just after the first cutting. #Scouting is an important component of effective alfalfa weevil management. #NFieldObs #NebExt @UNLExtension

Hairy vetch is an important legume #covercrop that can convert atmospheric #nitrogen into N that can be used by plants such as #corn and #sorghum. It can also suppress weeds. #NFieldObs #NebExt @AmitUNL @unlagrohort @UNLExtension

#CerealRye is Nebraska’s common grass #covercrop in corn & #soybean. Planted in fall, it helps control winter weeds like henbit & marestail. Terminate after planting to suppress summer weeds like #PalmerAmaranth. @AmitUNL @MarthaMamo3 @unlagrohort @UNLExtension #NFieldObs

Harvesters are urged to take precautions this week, as dry conditions & strong winds have increased the risk of rapid fire spread in #Nebraska & western Iowa. » buff.ly/4h37AWn #NebExt #harvest24 #drought #ag #cropproduction #wildfire #naturaldisaster @NebraskaClimate

All prevention and maintenance can be done perfectly but combine fires still can happen. Explore steps to be prepared when that disaster occurs. Key is to be prepared! #NebExt #Nfieldobs @UNLExtension

We have all seen the news articles about combine #fires then leading to large wildfire. Reminder of steps we all can take to help prevent combine fires. #EDEN #NFieldObs #NebExt

Herbicide-resistant Palmer amaranth is the most troublesome weed in corn-soybean production fields in Nebraska. @amitUNL discusses the three basic principles that should be adopted before or after it emerges. @MarthaMamo3 @unlagrohort @UNLExtension @andreabasche

#Planting cash crops into actively growing green #covercrops is referred to as planting green. It is crucial to time the termination of cereal rye correctly to ensure effective weed suppression without negatively impacting corn yields. @AmitUNL @unlagrohort @andreabasche
