Location: Based in Burt County with responsibilities there and in Thurston and Dakota counties; statewide responsibilities with soybean cyst nematode education Program Areas: Crop Production, particularly corn, soybeans & alfalfa; integrated pest management, particularly insects, diseases & nematodes Focus Area: Soybean cyst nematodes and soybean diseases Education: BS and MS degrees in agronomy (crop production option) from University of Nebraska-Lincoln
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.
Soybean cyst nematode is estimated to cause $40 million in lost soybean yields annually in Nebraska. Soil tests, available free through a program funded by the Nebraska Soybean Board, can help growers identify where this nemesis is a problem so they can manage that field accordingly.
If you noticed some areas of your soybean fields that didn't yield as well as expected, this fall would be a good time to soil test for soybean cyst nematode. In University of Nebraska research of SCN-infested fields, switching to an SCN-resistant variety increased yields as much as 6 bu/ac.
Nebraska soybean producers are being asked to answer a survey about their soybean fields and contribute to a benchmark study of current soybean production in Nebraska. Researchers from 10 north central states, including Nebraska, are collecting the data to identify factors that may be impeding growers from reaching full yield. See what they've learned in the first two years of the study and how they hope to use the information.
This week soybean aphids were found in several northeast Nebraska fields at low numbers. Although it has been too hot for soybean aphids to thrive, populations could quickly increase with cooler temperatures. Scouting is recommended at this time.
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.
Moth traps have been established at 12 sites in northeast, east central, southeast and south central Nebraska to monitor flights of armyworm, black cutworm, and variegated cutworm moths. The results are presented below and will be updated weekly through May.
