||Mode of action
||Weeds controlled and use
||Systemic contact herbicide (via the leaf). No residual life in the soil.
||Grasses, broadleaved weeds and clovers. Provides short-term weed control
||Avoid contact with desirable plants and immature bark.|
||Emulsifiable concentrate. Half-life in the soil of less than 24 hours
||Selectively controls grasses. Can be mixed with Versatil, Gardoprim or Simazine for controlling clovers and broadleaved weeds.
||Immediately after use, flush sprayer several times with clean water.|
|Glyphosate Roundup, Renew
||Absorbed through foliage and translocated to all parts of the plant, including roots. Half-life <14 days in aerobic soil, and 14-22 days in anaerobic conditions.
||Controls most annual and perennial grasses and broadleaved weeds. Used as a pre-planting or a release spray. Can be used successfully as a stump poison.
||Spray drift must not contact foliage or green-bark of desirable trees.|
|Interceptor (Organic spray - new product with limited information on weed control in establishing native plants)
|Emulsifiable, non-selective, contact foliage spray. Penetrates green plant tissue, and disrupts cellular physiology. Fast acting (within minutes) but may require additional treatment.
||Controls annual weeds and grasses, and perennial weeds. Can be used as a pre-planting or release spray.
||Spray drift may damage foliage, fruit or unprotected green bark of desirable plants. Also kills algae, mosses and liverworts.|
||Absorbed only through roots of germinating plants. Soil residual life ranges from 3 - 12 months. Half-life varies from 27-102 days. Low leaching potential.
||Prevents the emergence of a wide range of annual and perennial grasses and broadleaved weeds.
||Flowable Simazine - poison. Others - low toxcicity.
||Spray drift may cause serious damage to other plants.|
||Absorbed through roots and leaves. Pre- and post-emergent half-life in biologically active soils is 30 - 60 days.
||Controls a wide range of annual and perennial grasses and broadleaf weeds. Apply pre-planting or as a release.
||Follow manufacturers recommendations. Avoid using near desirable plants, where the chemical may be leached into their root region.|
||Absorbed by leaves, stems and roots.
||Controls thistles, yarrow, clovers and many difficult flat weeds. Can be mixed with other herbicides for the control of additional weeds. Do not apply to legumes or compositae (daisy family)
||Follow manufacturer's recommendations. Remains active on plant material - do not use clippings from treated areas for compost or mulch, within 6 months of treatment.|
