Nitrogen application timing effects on downy brome (Bromus tectorum) and winter wheat (Triticum aestivum) growth and yield.
The history and distribution of downy brome (Bromus tectorum) in North America.
Because of an atypical weather pattern in southern Idaho during the winter of 2001-2002, growth of invasive downy brome
was suppressed on all pastures during the first year of the study.
A few of these weeds - volunteer rye (rye that escaped harvest and sprouted the next season), jointed goatgrass, and downy brome - have been reduced by up to 75 percent in his studies near Akron, Colorado.
That's because wheat roots extend deeper into soil than those of downy brome and can extract fertilizer that's moved a couple of inches down.
Until we find alternatives to control weeds like downy brome
and Russian thistle, herbicides are crucial to make conservation tillage work," says weed scientist Alex G.
The crop rotation breaks up the life cycles of diseases like Cephalosporium stripe and of grassy weeds like jointed goatgrass and downy brome
Adding the summer annual crop helps control winter annual grassy weeds such as jointed goatgrass, downy brome
, and volunteer rye that are a problem in the wheat-fallow rotation.
Planting peas or barley in the spring breaks the growing cycle of winter annual grassy weeds such as downy brome
and jointed goat grass.
