Flood waters likely moved weed seeds, possibly introducing invasive or particularly problematic weeds in new areas of the state. Management of many of these weed species is best achieved early season when several practices may be integrated to achieve control.
Scotch thistle, which can now be found throughout much of North America, is an invasive weed from Eurasia threatening areas along rivers in western Nebraska. Early control efforts are essential to management.
A description of marestail's history as an invasive weed in pastures and its management. Herbicide applications for marestail in pastures and rangeland may be most effective if applied in very early spring from April through early May.
With limited precipitation and warm temperatures this week, dry beans turned quickly and harvest has started. Conditions should provide for good data collection from on-farm research of using direct harvesting methods.
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.
