N Field Observations

Keeping a close watch on the rapidly changing situation with Southern rust and Tar spot in our fields, Tamra Jackson-Ziems, discusses this emerging issue and ways to manage other notable bacterial diseases. @tjcksn podbean.com/ew/pb-wt99p-16… #NebExt #NFieldObs

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

Planting annual #forages and #covercrops in #drought? Check out our demo plot at Middle Niobara NRD in Valentine! @NebraskaNRDs #NFieldObs #NebExt

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

#VolunteerCorn is a problematic weed in Nebraska's crop production fields and poses a significant challenge in #sorghum cultivation. @AmitUNL discusses the herbicide, quizalofop (FirstAct), and how it can be used to manage volunteer corn in Double Team sorghum. @UNL_CropWatch

This week Extension Educator, Steve Melvin, discusses tips to quickly evaluate your center pivot’s performance while it is running. @UNL_CropWatch @UNLExtension #NfieldObs #NebExt

Southern #rust has made its appearance in NE. What impacts does it potentially have on 2024 #corn yields? Which fields are at the highest risk? #NFieldObs #NebExt @tjcksn @CropNetwork @AmyTimmerman2
