Goosegrasses in nut orchards
Cross-post from UCWeedScience In the past couple of years, I’ve gotten a lot of questions about goosegrass in orchard production systems, particularly about suspected glyphosate-resistant biotypes. From a California orchard standpoint, we have two main goosegrasses (Eleusine spp) to deal with; these are goosegrass (Eleusine indica) and threespike goosegrass (Eleusine tristachya). These species are fairly similar but have quite different flowers (see the photo below).
