| Abstract/Contents: | Two field experiments were combined to compare the effects of Ethrel, EL 500, Embark, PP-333, and Limit on stem and leaf of Kentucky bluegrass at three different seasonal stages of growth. Embark was the most effective in controlling growth, followed by Ethrel. EL 500, PP-333, and Limit were least effective. EL 500 was the only chemical to show no toxicity over all seasons. PP-333 caused only slight discoloration, while Ethrel and Limit showed more. Embark severely damaged the leaves and apical meristems causing the turf to brown. Carryover effects through winter were studied in the spring. Embark eliminated spring heading, while all other chemicals were ineffective. Spring green-up of these plots showed the toxic effects of Embark, PP-333, and Limit. Ethrel was the only chemical to remain active in leaf growth inhibition. A potential advantage provided by Embark and Ethrel was shown in their ability to inhibit spring heading and early spring leaf growth, respectively when applied the previous fall. |
