Atrazine (11.2kg/ha active ingredient) was applied in 1967 and 1968 to three areas of the northern Mohave Desert to destroy perennial shrub cover. Of the 23 perennial species 12 were completely eliminated. Two species, Mohave Yucca (Yucca schidigera) and big galleta (Hilaria rigida) showed no effects. Plants of creosote bush (Larrea tridentata), Nevada Ephedra (Ephedra nevadensis), and range ratany (Krameria parvifolia) were severely damaged but many survived through crown sprouting. Scattered plants of the invading species shadscale (Atriplex confertifolia), desertalyssum (Lepidium fremontii), and Russian thistle (Salsola paulsenii) became established by 1975 on the fertile mounds under killed shrubs. Glasshouse tests of seedling survival on soils sampled eight years after treatment showed 65 to 95% mortality, as compared to 3 to 8% mortality on control soils.
