| Abstract/Contents: | "An increase of turfgrass density can be achieved by the use of trinexapac-ethyl growth regulator. Increased turf density reduces opportunities for germination of weed seeds. In two studies conducted during dry and rainy season trinexapac-ethyl was applied at 0.1, 0.2, and 0.4 kg ha⁻¹ on a mature stand of weed free 'Tifgreen' bermudagrass under an intensive management regime. All treated plots and control plots were seeded with crabgrass (Digitaria spp.) two days after trinexapac-ethyl application. There were significant differences between treatments within both dry and rainy seasons and also substantial differences between seasons despite adequately applied supplemental irrigation. Application of trinexapac-ethyl at 0.1 kg ha⁻¹ was the most beneficial. Application rates at 0.2 and 0.4 kg ha⁻¹ caused moderate turf injury however within 3 to 4 weeks turf recovered and became denser than control. In all instances denser turf effectively prevented infestation with crabgrass. Magnitude of these changes and possible reasons for observed differences will be discussed." |
