Key Words: Weed Control, Soybean Cyst Nematode (SCN)
Soybean cyst nematodes (SCN) are the most limiting disease of soybeans in the United States and about 10% of Nebraska soybean production fields are infested with SCN. Research has been reported that SCN can reproduce on selected winter weeds. Unknown is whether the SCN can reproduce on these weeds in Nebraska’s winter environment.
The objectives of this project are to:
• Measure the emergence, growth, and survival of key winter annual weed species in Nebraska;
• Measure the effect of four common winter annual weed species on SCN population density;
• Measure the effect of henbit density and removal time on SNC density; and
• Determine if SCN can complete its lifecycle after a winter annual weed has been treated with a herbicide.
