Abstract
2-Amino-4-methylphosphinobutyric acid or its metal salts, or acid-addition salts thereof are used as perennial weeds and brush controlling agents. The L-isomer is twice effective than the racemic acid. The perennial weeds and brush controlling effect may be obtained by foliar application over a prolonged period.
