Glyphosate-Resistant Waterhemp Arrives
Glyphosate resistance has been confirmed in waterhemp in six Nebraska counties. Even if you're not farming in one of them, don't be surprised to see problems this year as resistant genes can travel via pollen in the wind. MORE
Winter Wheat Condition Varies Widely
Dry conditions last fall and winter followed by hard freezes in April are taking a toll on some wheat in the Panhandle and southwest Nebraska. Conversely, cool, wet conditions in southeast Nebraska have led to soilborne wheat mosaic disease. See Field Updates & WSBM
April 26, 2013
- Glyphosate-Resistant Common Waterhemp Confirmed in Nebraska. Resistant populations in Antelope, Dodge, Lancaster, Pawnee, Seward, and Washington counties reinforce the need to rotate herbicide modes of action to reduce resistance from developing.
- Wheat Soilborne Mosaic in Southeast Nebraska Wheat. Favored by wet soils and cool temperatures, symptoms from this disease would be expected to wane as temperatures rise. Planting resistant cultivars is the best management strategy.
- Freezes Stress, Injure Wheat; Rains Bolster Soil Moisture, but Subsoil Still Lacking. Catch up with field reports from educators and specialists across the state.
- Drought Outlook Improves for Eastern Nebraska. Only 78% of the state is in one of the two worst drought categories, compared bo 91% last week. Southeast corner of the state one step from being drought-free.
- Record-Setting Cold, Wet April About to Improve. April rains have been nothing short of "remarkable," although cool temperatures will likely make this one of the top five coldest Aprils since 1895.
- ACRE or DCP? UNL Webinar Examines Features and Future of Each. An extension of the 2008 farm bill requires producers to reselect whether they want to participate in the ACRE or DCP farm programs. Learn more in these April 29 and May 3 webinars.
- Bean Leaf Beetle Numbers Down, but Hot Spots Still Possible. Insecticide seed treatments are keeping numbers in check, but beetles are still present and pockets of relatively high populations can cause problems.
- Western Nebraska Likely to see Fewer Grasshoppers Again in 2013. However, while the risk is lower, there could be pockets of damage in western and north central Nebraska pastures and rangeland.
Alfalfa & Forage Production
- Your Next Options after Rain Delays Alfalfa Planting. Consider no-till seeeding and using a burndown or postemergence weed control to speed up planting.
- Forage and Pasture Plants Still Weak Despite Rains
