Abstract/Contents:"The control of weeds and other grasses is a principal production problem in Kentucky bluegrass grown for seed. Annual weeds are one of the major factors limiting successful stand establishment. No grass seed is harvested during the establishment year. Planting a companion crop such as spring wheat with Kentucky bluegrass could allow some economic return during the establishment year, but also may reduce Kentucky bluegrass stand establishment. A competition study was established in May 1993 to assess the competitive effects of a "Wakanz" spring wheat companion crop and wild oat against Kentucky bluegrass. Wheat and wild oat were planted in a split-plot randomized block design, and the densities attained were 33, 58, 95, 142 and 146 plants/m2 for wild oat and 40, 59, 104, 161 and 184 plants/m2 for wheat. Kentucky bluegrass variety 'Glade' was seeded perpendicular to the crop and weed on the same day at 3.4, 6.7 and 10.1 kg/ha. Kentucky bluegrass biomass at late boot stage of wheat was reduced to 28% and 25% of the control, at the lowest density of wild oat or wheat, respectively. The Kentucky bluegrass seed harvest in July 1994 should demonstrate whether the bluegrass is able to recover from this early competition to sustain adequate yields. The substitution of estatlished burning practices for residue removal with non-thermal methods is likely to have a great impact on the weed population and spectrum. A crew-cutting vacuum machine that removes residue is being tested in combination with herbicides to determine the effects on weed control in established Kentucky bluegrass. In a randomized complete block design 1 spring applied and 8 fall applied herbicide treatments were tested on a crew-cut area of Kentucky bluegrass at two locations. Both sites were in the second seed year, At both locations the spring applied treatment of fenoxaprop-MCPA-2,4-D injured the Kentucky bliegrass 98% which was reflected in the reduced mumber of panicles and low seed yield. Most of the other herbicides controlled weeds effectively."
