REVIEW OF INTEGRATED WEED MANAGEMENT FOR ONTARIO ROADSIDES

This review investigates integrated weed management (IWM) techniques that could apply to roadside vegetation management in Ontario conditions. IWM incorporates multiple approaches including cultural practices; biological weed control; competitive vegetation; allelopathic species; and mechanical, physical and chemical control. Competitive vegetation could be incorporated by encouraging development of naturally occurring communities of herbaceous or shrub vegetation that are resistant to invasion by weeds or brush due to allelopathy or competition. In more intensively managed areas, planting of competitive ground covers is an alternative. Roadside turf mixtures should be evaluated with competitive ability as a prime consideration. Establishment of vegetation on construction sites should promote rapid, vigorous growth of desirable plants to minimize invasion of weeds on exposed soil. In existing turf areas, maintenance should encourage vigorous growth to compete with undesirable vegetation. Targeted mowing of noxious weeds may augment chemical and cultural control efforts. In the long term, biological control agents could be used to supplement other methods. There is a need for continued development of chemical control options to optimize effectiveness by improved timing and to expand the use of targeted applications. Chemical control can be combined with technologies such as cut surface applications for brush control, and programs of herbicide use, mowing, fertilization and overseeding for noxious weed control. The development of IWM programs is discussed and sample IWM programs are outlined for 1) brush control and 2) noxious weed control in turf areas. The report concludes by summarizing existing technologies, and ones requiring further development under Ontario conditions.
