Five rates of 1-(2 methylcyclohexyl)-3-phenylurea (siduron) were applied to Cohansey and IaGreen cultivars of creeping bent-grass (Agrostis palustris). Siduron had no effect upon leaf respiration or photosynthesis of either cultivar. Cohansey was tolerant to 100 lb/A of siduron while top growth of IaGreen was reduced 90% at 1.5 lb/A. Siduron inhibited new root growth of the IaGreen cultivar and decreased root respiration.
