Abstract

Intensive cattle grazing in May and June reduced yellow starthistle plant size, summer and fall canopy size, and seed production in the first year of a 3-year, northern California study. Combining grazing and herbicide applications caused large reductions. Abundant late rains favored yellow starthistle growth.
