Abstract/Contents:"There are several methods of controlling weeds in Turf varying through cultural practices such as weeding and maintaining dense turf coverage to the application of herbicides. Herbicides themselves come in several forms and work in several ways. The major categories of Herbicides are [pre-emergence and post-emergence]. These two categories can then be subdivided into [selective and total]. This gives us four new categories: [pre-emergence - total (Ustilan), pre-emergence - selective (Kerb), post-emergence - total (Roundup), post-emergence - selective (Bindii Killer)]. As turf managers, except in very specific and limited areas such as footpaths and car parks, the two areas of particular importance to us are selective pre-emergence and selective post-emergence. There are two ways that herbicides can enter a plant. Firstly through the green, above the ground parts such as leaves or stem, secondly through the roots. Many herbicides are either specifically taken up through the foliar parts or, alternatively the roots only, however some herbicides can be absorbed by both root and leaf - usually such a herbicide works much better by one means uptake than the other... We are extremely limited in the weed control avenues open to us. In all the various categories of pre and post emergence selective herbicides, only 16 (now 15) products are available, often under several trade names and in many different mixtures. When using a selective herbicide we must always be aware that few, if any herbicides can be said to be selective under all conditions. At high rates of application for instance, all herbicides are less selective to young plants and should not be used on newly laid turf. By the same token some products will control only the vulnerable young stages of the target weed and will have no effect after the weed reaches a certain growth stage. The universal rule when using herbicides, or any pesticide is READ THE LABEL. For a selective herbicide to work properly several factors come into play, growth stage of weed, growth stage of crop, temperature, light, dilution rates, nozzles - if these are likely to alter the effectiveness of a product they will be clearly stated on the label." Includes a list of herbicides and their characteristics and uses.
