Use of Ronstar and Barricade for Pre-Emergence Control of Poa Annua at Overseeding. Both of these per-emergent herbicides have been applied in 1998 at six and eight weeks before overseeding with perennial ryegrass to see if they will allow adequate germination of the rye and suitable control of Poa annua. Some treatments had poor initial stand density. Weed control varies with product, application, timing and use rate. The idea is to find an ideal treatment which affords overseeding and adequate control of poa.
Future funding depends on results.
Subsurface Drip Irrigation for Turf. Plots of Midiron bermudagrass are being irrigated either by sprinkler or by subsurface tape. The first year's data shows little benefit in water savings by using subsurface, relative to sprinkler. Development of a Dwarf Type Saltgrass for Golf Courses. K.B.
