Heavy populations of immature grasshoppers were found in field borders in south central Nebraska corn fields this week. Scout and if numbers warrant, treat now when they're small and concentrated in borders. See story for identification tips, treatment thresholds, and control recommendations.
While European corn borer numbers have greatly decreased regionally since the introduction of the first Bt corns, local populations may still cause damage on untraited corn such as popcorn or white corn or in field planted to non-BT corn to take advantage of lower seed costs. These fields should be scouted now.
After recent severe storms that rolled across parts of Nebraska, growers are encouraged to wait 7-10 days to fully assess crop damage and determine next management steps. Research-based estimated yields from replanting now are included.
Hail strikes Nebraska crops each year, creating uncertainty and questions for farmers: “Does the level of damage warrant replanting or will the remaining stand yield better than a replant would? How should I adjust inputs for the remaining season? Would a cover crop be cost effective?”
Seeding year alfalfa is just getting its "field legs" and needs to be managed differently than established alfalfa. Stems are spindly, roots are small and growth is slower. Following these harvest guidelines can help assure multiple harvests and a strong first season.
Dalmatian toadflax is a perennial herb that spreads quickly in disturbed pastures and rangelands. Prevention is the best and cheapest management option; once established, mechanical, biological and chemical measures may help achieve control.
As Excel workbooks get more complex, it often becomes necessary to review different parts of a spreadsheet or different spreadsheets in the workbook at the same time. Using multiple windows can be a real time saver, helping users be more effective.
The High Plains Ag Lab Field Day, scheduled for Thursday, June 21, will highlight UNL research on dryland crops, especially field pea and winter wheat, as well as grazing and forages. View field trials and hear reports from researchers.
This week's USDA NASS Nebraska Crop Condition Report rated corn as 86% good to excellent and soybean, 87%. Progress for both crops was similar to or ahead of 2017 and the average. Winter wheat condition was 68% good to excellent.
