Selective herbicides eradicate a specific type of plant. 4. Crop management practices, such as banding rather than broadcasting nitrogen, and the quick establishment of a competitive crop, help to control the spread. Winter wheat yield, expressed as a percent of the weed-free control, also was regressed against imazamox rate using the same equation but with … Downy brome (Bromus tectorum) continues to be a problematic and widespread weed in inland PNW wheat-fallow rotations. Pre-plant glyphosate applications are somewhat effective at keeping downy brome populations from getting out of hand as this weed will germinate in the fall. Its presence in the southwest and its ability to infect many habitats makes it a threat to winter and spring cereals, dryland hayfields, pastures and rangelands. Downy brome is one of the earliest plants to get going in the spring, says Neeser, which makes it a particular challenge in winter wheat. Imazapic Effects on Competition Dynamics Between Native Perennial Grasses and Downy Brome (Bromus tectorum). Initially cheatgrass was only present as isolated populations, but it has since become one of the most widely distributed plants (invasive or native) in all of North America. There simply are no herbicides that control downy brome in-crop. This publication outlines both how to identify prickly lettuce and how to manage it in wheat.
