Improving Soybean Profitability: SCN
March 3, 2017
The easiest and least expensive way to improve profitability for many soybean growers in tight economic times, or any time, is to sample fields for soybean cyst nematodes (SCN). In Nebraska trials growers realized an average six-bushel-per-acre soybean yield increase after taking no-cost steps to manage SCN.
SCN Scouting Recommendation Changes; SCN Resistance Possible
July 8, 2016
Mid-summer is an effective time to scout for soybean cyst nematode (SCN) using either the visual or soil test method. This story describes both methods. If SCN is identified, a follow-up soil test approximately six years later can help assess effectiveness of treatment efforts as well as identify SCN resistance.
Herbicide Injury and Pathogen Infection on Soybean Seedlings
June 17, 2016
In an ongoing survey for soilborne pathogens in soybeans, closer examination of soybean seedling injury in a Keith County field found several causes, including herbicide injury and damping off from Fusarium or Rhizoctonia root rot.
UNL Plant and Pest Diagnostic Clinic June 15 Update
June 15, 2016
The UNL Plant and Pest Diagnostic Clinic lists the diseases they've found in the past two weeks in corn, soybean and wheat samples submitted from various districts in Nebraska.
Corn Nematodes: Scout Sandy Soils Now, Other Soils Any Time
June 7, 2016
This year nematode damage in some Nebraska fields may be masked by the ample rainfall we’ve received, but rest assured, these plant parasitic nematodes are still there in almost every field. Their impact ranges from no obvious sign to severe crop injury and tremendous yield loss.
Stripe Rust Increasing; Spray Your Wheat to Protect the Flag Leaf
June 2, 2016
Stripe rust has significantly increased in all wheat-growing areas in Nebraska. It is recommended that wheat be treated with a fungicide to protect the flag leaf. If the incidence (percentage of flag leaves diseased) or severity (percentage of the flag leaf area diseased) is less than 50%, spraying a fungicide will significantly reduce yield loss due to stripe rust.
Seedling Diseases Continue to Develop in Nebraska Corn
June 2, 2016
Following several weeks of rainy conditions, seedling diseases are becoming more apparent in corn. See what symptoms to look for when scouting fields.
