Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with CO₂ precision plot sprayers. Unless otherwise indicated, preplant...

Field experiments were conducted in 2002 and 2003 in the Willamette Valley of Oregon to investigate the effects of two plant growth regulators on the growth and reproduction of the weed annual bluegrass. Previous research suggested that the plant growth regulator prohexadione-calcium hastened senescence of annual bluegrass. Another plant growth...
A two year study was conducted at two locations to determine the effect of three perennial ryegrass (Lolium perenne L.) row spacings on creeping bentgrass (Agrostis stolonfera L.) biomass and seed production. At Location 1 in 2002, the creeping bentgrass biomass within the 7.62 cm row spacing was less than...
