Setaria faberi, the Giant Foxtail, also known as Chinese foxtail, Chinese millet, giant bristlegrass, or nodding foxtail, is an Asian grass. It is a summer annual, with plants emerging from seeds in the spring, and setting seeds in the late summer or fall.

Giant foxtails prefer compacted soils, high in nitrogen and phosphorus. The plant gains a competitive edge on crops as the soil pH increases.

As a weed[edit]

Giant foxtail has been introduced to North America, where it is a widespread weed. It is a significant pest of corn, reducing crop yields by 13-14% at average plant distributions. Mechanical control of giant foxtails by night tillage, rotary hoeing, or flaming is very difficult. Crop rotation with two years of alfalfa effectively reduces giant foxtail populations. Herbicides can effectively control the plant when it is growing amongst broadleaf crops, but are less effective when it is infesting corn.[1]
