Abstract/Contents:"Single applications of herbicides were applied in March at the recommended rate, and one half that rate followed with and without sequential applications at 60 or 90 days at one-half the initial rate. Recommended rates and herbicides included 1.5 ai/ha oryzalin + 1.5 kg ai/ha benefin, 3.3 kg/ha oryzalin, 3.3 kg ai/ha pendimethalin, 1.5 kg ai/ha prodiamine, 2.2 kg ai/ha flumetralin, 3.3 kg ai/ha oxadiazon, and 6.6 kg ai/ha napropamide. In general, sequential applications were better than single applications and 60-day sequential applications were better than 90-day sequential applications, especially if the initial application was at one half the recommended rate. Crabgrass control was at least 80% with oryzalin, prodiamine, pendimethalin, flumetralin and napropamide when applied at the recommended rate and followed by a sequential application 60 days later. These herbicides as well as oxadiazon and benefin plus oryxalin maintained 80% or greater control of crabgrass with an initial application at the recommended rate followed by a sequential application 90 days later. Prodiamine applied at one half the recommended rate followed by a sequential 60 or 90 days later also gave 80% or greater crabgrass control. The number of goosegrass plants per square meter was significantly reduced by oryzalin, pendimethalin, proiamine, flumetralin, oxadiazon, napropamide and benefin plus oryzalin when applied at the recommended rate and followed by either sequential application. In another experiment, 0.6, 1.1, and 2.2 kg ai/ha MON-15126 applied in March maintained crabgrass control of 80% or greater through October."
