Abstract/Contents: | Endothall (7-oxabicyclo(2.2.1)heptane-2,3-dicarboxylic acid) has shown selective toxicity toward annual bluegrass (Poa annua) in Kentucky bluegrass (Poa pratensis) and creeping bentgrass (Agrostis palustris) turf. At relatively low application rates, (0.25 to 0.5 lbs/A ae) the growth rate of annual bluegrass plants may be substantially suppressed with little or no suppression of the perennial grasses. At higher rates (2 to 4 lb/A ae), an overall browning of the turf may occur followed by a selective vegetative recovery of Kentucky bluegrass. Annual bluegrass is frequently killed and bentgrass injured from these higher application rates. Annual bluegrass generally recovers from seed in bare areas where the perennial grass has not filled in. Hence, a follow up treatment by a pre-emergence herbicide may be necessary to preclude reinfestation. The actual toxic effects exhibited by annual bluegrass, following endothall treatment, are highly variable and depend not only upon the application rate, but the temperature, moisture condition and the physiological state of the plant. |
