7 INTRODUCTION This report is compiled to inform industry, extension and research personnel of the weed management research conducted at the Department of Plant griculture, University of Guelph, Simcoe, Ontario during The herbicides listed in this report do not constitute a recommendation for use. Please consult the Ontario Ministry of griculture, Food and Rural ffairs, Publication 75 -Guide to Weed Control" for approved chemical recommendations. dditional copies of this report as well as more detailed information are available on request. We acknowledge the assistance and cooperation of Peter White and Bob Roy for trials coordinated at the Southern Crop Protection & Food Research Centre (Delhi). We acknowledge the assistance of Paul Zeldon, ndrew Dale, Kris Heil, Kelly O'Neill, Shannon O'Neill, and Lee nn Van Hooydonk, our summer research assistants. We acknowledge the cooperation and assistance provided by chemical companies; the chemical samples supplied as well as monetary assistance. We also acknowledge funding from OMFR Food Systems 2002, Pickle Packers International- Chicago, Ontario ProceSSing Vegetable Growers, NSERC, OMFR Special Research Fund, gricultural daptation Council, PMR, IRP, FC, MultiFoods (Sicks), and OFVG. J.O'Sullivan, S. Lonsbary and R. Grohs MTERILS and METHODS Liquid formulations were applied with a R+D research sprayer (back pack) using CO 2 as a source of pressure. Unless otherwise stated, applications were made at the rate of 200 liters per hectare at 200 kpa pressure using XR 8002 Tee Jet nozzles. Nozzles were set at 50 cm apart with a boom length of 1.5 or 2.0 m, depending on the plot size. Boom height was set to 50 cm above the target. ll chemical rates are expressed as kilograms of active ingredient per hectare. In several abstracts, a visual rating system has been used to evaluate weed control and crop tolerance. The system used is advocated by the Expert Committee on Weeds. The scale is linear from For weed control, 0 = no control, complete control. For crop tolerance, 0 = no injury and 100 = death to crop. In several abstracts, a weed biomass is used to evaluate the weed densities. The weed biomass ratings represent a count of the number of weeds present in the plot (1m2) multiplied by the average height of each species (cm). This number is then expressed as a percent of the untreated check. Negative percentages denote zero control for that particular weed species. -1-
