Watergrass seed request (482KB)

The UCCE Rice Team is conducting a field survey to collect watergrass samples over the next few weeks. The samples will be used to develop chemical and non-chemical management plans for watergrass.

We are looking for all types of watergrass: "mimic", early watergrass, late watergrass, barnyardgrass, and the new species that we started seeing a couple of years ago. See attached flyer for pictures.

For more information, and if you are interested in having us come out and sample your field(s), please contact Whitney Brim-DeForest (wbrimdeforest@ucanr.edu), or call 541-292-1553.
