Coyote brush; coast sage- brush; purple and white sage; mixed coastal brush; chamise; chaparral; oak woodlands; big sagebrush Coyote brush. Encroachment of coy- ote brush onto pasture land can well be handled by the use of chemicals. This was demonstrated by the late J. T. Mc- Namara, Farm Advisor of San Mateo County. From a series of tests, in 1945 and later, he found that 2 to 3 pounds per acre of actual 2,4-D (acid) as the amine salt would kill coyote brush. Ap- plication by helicopter in May or June, with the amine of 2,4-D in 10 gallons of water per acre, has become standard practice. Results of recent tests have shown that coyote brush could be killed as late as September 1 by adding 1 gallon of light emulsive summer-spray oil to the mixture containing 3 pounds of 2,4-D (amine form) and S1/^ gallons of water per acre. In tests by Bryan Sandlin, Farm Advisor in San Mateo County, and others, this combination has given excellent control in June. Although oil is not necessary at this time, it is ad- visable where growth conditions are not optimum. Some poor results in 1951 may be attributed in part to the fact that no oil was added to the spray mixture. Left: Coyote brush killed by the use of 2 pounds of brush killer per acre, applied by helicopter in 1 gallon of Diesel oil and 8V2 gallons of water. Note the abundance of grass in the formerly dense brush area. (George Wheelwright ranch in Marin County.) Right: California coast sage- brush controlled (almost 100 per cent) by 2,4-D, applied at the rate of 2 pounds per acre (amine salt) in 6 gallons of water. Note the abundance of grass. On the right the sprayed area was disked several months after spraying. (Sedgewick ranch n
