Abstract

The carbon banding technique was evaluated for control of volunteer Kentucky bluegrass (Poa pratensis L.) while Kentucky bluegrass was established for seed production. At Madras, Oregon, where terbacil (3-tert-butyl-5-chloro-6-methyluracil), diuron [3-(3,4-dichlorophenyl)-1,1-dimethylurea], atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine], and simazine [2-chloro-4,6-bis(ethylamino)-s-triazine] were applied at several rates each, volunteer Kentucky bluegrass control between the carbon bands ranged from 80 to 99+%. At Corvallis, Oregon, where Colonial bentgrass (Agrostis tenuis Sibth. ‘Highland’), red fescue (Festuca rubra L. ‘Pennlawn’), perennial ryegrass (Lolium perenne L. ‘NK-100’), and orchardgrass (Dactylis glomerata L. ‘S-143’) were planted to allow identification of volunteer Kentucky bluegrass both between and in the carbon bands, diuron, atrazine, and a combination of diuron and terbacil eliminated volunteer Kentucky bluegrass. Terbacil did not control all Kentucky bluegrass between the bands. None of the herbicide treatments adversely affected crop establishment or seed yield.
