Giant
foxtail is the only grass on Indiana's list of restricted noxious weeds.
Giant foxtail is closely related to green and yellow foxtail but these
two weeds are much smaller and not as damaging as giant foxtail.
It is an annual grass with a very shallow root system. |

If you
look at the seed head of giant foxtail you will see that there are 3-6
bristles attached to each seed and the seed head bends over as it matures.
This is a characteristic that can help distinguish giant foxtail from the
other foxtails. |

The seed
of giant foxtail is light green to yellow and will still have the lemma
and palea attached. Giant foxtail is a very troublesome weed in Indiana
soybean and corn fields. Because it produces so many seeds per plant,
it spreads very rapidly if not controlled. The seeds of Giant foxtail
are larger than the seeds of Green and Yellow foxtail. |
