Title: EVALUATIONS OF IMAZETHAPYR AND IMAZAPYR FOR EFFECTIVE SUPPRESSION OF ROADSIDE VEGETATION
Accession Number: 00489658

Availability: Find a library where document is available Abstract: The objective of these studies was to evaluate rates and mixtures of imazethapyr and imazapyr with isopropylamine (1:1) plus imazethapyr combinations for growth suppression, seedhead control, and turf discoloration of tall fescue (Festuca arundinacea Schreb.) intended for highway roadside turf. Imazethapyr applied alone at rates of 25 to 123 g/ha provided effective suppression of height for 4 to 9 weeks, controlled seedheads, and generally failed to discolor turf to unacceptable levels. More discoloration was evident in turf treated with imazethapyr plus imazapyr combinations in comparison with turf treated with imazethapyr alone. Rates of 94 + 5.0 to 123 +4.4 g/ha imazethapyr plus imazapyr, respectively, provided good growth and seedhead suppression, and although discoloration occurred, turf generally recovered following termination of suppression.
