| Abstract/Contents: | "The objective of this study was to evaluate the effect of a preemergence herbicide applied on Kentucky bluegrass (Poa pratensis L.) seedlings derived from seed treated with and without plant growth regulators (PGRs). Propiconazole 1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2yl] methyl]-1 H-1,2,4,-triazole at 1.9 g a.i. kg-1 of seed or seaweed extract at 13 g of product/kg of seed were applied to Kentucky bluegrass seeds prior to seeding. Preemergence herbicide, pendimethalin (N-(1-ethypropyl-3,4-dimethyl-2,6-dinitrobenzenamine), was applied at 3.3 kg a.i. ha-1 and 6.6 kg a.i. ha-1 six weeks after seeding Kentucky bluegrass when seedlings were in the two-leaf stage. Regardless of herbicide treatment, propiconazole or seaweed extract applications enhanced root development. Pendimethalin caused shoot injury up to five weeks after treatment. Plant height increased with PGR treatments when no herbicide was applied, but no significant plant height effect was obtained when herbicide alone was applied. The inhibition of shoot mass with the low dosage of pendimethalin appeared to be associated with an increase in root mass. However, at the high herbicidal dosage, a significant reduction of root mass occurred when compared to the low dosage results. These results suggest that seed treatment with propiconazole or seaweed extract may reduce preemergence herbicide shoot injury of seedlings." |
