The last year seemed to be a concerning one in terms of weedy rice issues in California.  While the year ultimately ended with overall low occurrences of the weed species, there was a troubling discovery of a new biotype. “We’re getting a lot of reports but low numbers that are new locations, but we did have one new biotype identified this year, said Whitney Brim-DeForest, UC Rice Farm Advisor for Sutter, Yuba, Placer and Sacramento Counties.  “So, good and bad.”

Brim-DeForest described the characteristics of the new biotype as being easily mistaken for type 4 at first glance.  “The seed looks a lot like our type 4, so it’s black hulled with awns again.  So very similar to the type 4,” Brim-DeForest noted.  Growers who may need assistance in identifying weedy rice in their fields can visit the California Weedy Rice website.
