Sprayed 8 areas with aquatically labeled Roundup for yellow-nut sedge release combined with woody vegetation control. About half produced fair to good stands of yellow-nut sedge with this one being the best. The other areas produced very little nut sedge. Hard to know if the lack of release was due to a lack of seed/tuber source there or too dry at that location. We had just started into a dry cycle at the time of spraying. Quality release depends on good moisture. All of the green vegetation is yellow-nut sedge.
