Abstract

If the 1950's became known to California rice growers as the years in which broadleaf weeds were finally controlled, then the 1960's appear to be the years in which grassy weeds—especially watergrass or barnyard grass—might also be brought under control with the use of selective chemicals. Preliminary tests and observations described in this report indicate that propanil, applied as a postemergence spray, and Ordram, a granular material applied at the preflood stage, may offer good control of watergrass in California rice fields which are continuously flooded during the growing season.
