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
Giant foxtail has been introduced to North America, where it is a widespread weed. It is a significant pest of maize/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 maize/corn because they are both Poaceae.[4]
