Abstract/Contents:"Endothall (7-oxabicyclo (2.2.1) heptane -2,3-dicarboxylic acid) was evaluated for the control of annual bluegrass (Poa annua L.) infestations in Kentucky bluegrass (Poa pratensis L.) and creeping bentgrass (Agrostis palustris Huds.) turfs. Foliar spraying of single-plant sand cultures of the 3 grass species resulted in selective growth suppression of annual bluegrass at certain rates and numbers of applications. Field spraying produced results varying from partial to complete browning of the turf depending upon the season. Generally, warm weather of late summer favored greater foliar browning of all turfs, followed by selective recovery of Kentucky bluegrass in 3 to 4 weeks. Bentgrass was moderately injured from these treatments while nearly complete eradication of annual bluegrass occurred. Applications of 50 ppm solutions of endothall to the roots of the 3 grasses in sand culture resulted in selective kill of annual bluegrass. Granular endothall formulations, applied to field turfs, produced similar results at rates as low as 9 kg/ha. The efficiency of control was greatest when the underlying soil was a sandy loam, low in organic matter."
