Footnote 1 Consultation on the proposed MRL for triclopyr is being conducted via this document (see Next Steps , the last section of this document). Garlon 3A and Garlon 4 are brand names of common triclopyr herbicides. There are numerous chemical treatment options available to manage Canada thistle. 4 Changes in vegetation, rather than toxicity of triclopyr itself, may affect populations of beetles, butterflies, and spiders. Triclopyr, formerly only available as a brush killer but now available to control weeds, is probably the best herbicide for killing creeping Charlie, according to Cooperative Extension specialists. It remains active in decaying vegetation for about 3 months. A breakdown product of triclopyr called TCP* is slightly to moderately toxic to fish and shellfish.4,5 For water fleas, the acid and salt forms are practically non-toxic, but the ester form is slightly to moderately toxic.5 Triclopyr is practically non-toxic to bees.4,5 Data is not currently available on the long-term toxicity of triclopyr to Western wheatgrass was highly tolerant of triclopyr and was only negatively affected by residue levels found in study soils for a few hours after applications.

Health Canada recently re-evaluated the use of glyphosate, finding no unacceptable risks to human health or the environment when used as directed.” [3] Health Canada is taking this stance even as Bayer-Monsanto has been losing court case after court case in the U.S. to juries awarding billions in damages to individuals harmed by the pesticide. Many herbicides are available with triclopyr as the key ingredient (Table 3). Another of the strongest weed prevention solution that you can take advantage of is the Southern AG 2,4-D Amine. Products containing aminopyralid, clopyralid, chlorsulfuron, dicamba, metsulfuron, picloram (Restricted Use), triclopyr, glyphosate (non-selective) and 2,4-D have been shown to work. Toxicological studies show no evidence that triclopyr causes cancer, birth defects, genetic damage, genetic mutations, or adverse effects on the immune system or nervous system in humans. • Do not apply more than 2 qts . It is non-toxic to bees but highly toxic to fish. Alkali sacaton and Canada wildrye were also sensitive to triclopyr, with predicted I 20 values of 2.1 − 3.6 d for soils with fast to moderate degradation profiles. In the province of Quebec (Canada), the phytocide Garlon 4, whose active ingredient is triclopyr, is often used to prevent trees from reaching electrical conductors.The object of this paper is to assess the potential health risks in workers coming into contact with Garlon 4.Ten workers collected their urine during the 22 hr following the beginning of a work shift. • Do not apply Alligare Triclopyr 4 to golf course greens . The object of this paper is to assess the potential health risks in workers coming into contact with Garlon 4 ® . Many wild violets started wilting within a a few weeks. TCP is moderately toxic to fish [9]. [Explanation of LC50s] Table 5: Available toxicity values for triclopyr acid, triclopyr BEE and Garlon RTU. Triclopyr is a broadleaf herbicide used primarily on pastures, woodlands, and rights of way. Triclopyr degrades rapidly in water. In bermudagrass and zoysiagrass, metsulfuron and flazasulfuron are effective wild violet control herbicides. 7 *TCP: trichloropyridinol Triclopyr will control many of Canada's problemat ic woody species, such as alder, ash, beech, birch, poplar and maple. It is a highly effective selective weed killer, which is truly appropriate for your needs if what you are trying to control are broadleaf weeds. Canada.

Two forms of triclopyr are used as herbicides: the triethylamine salt (found in Garlon 3A) and the butoxyethyl ester (found in Garlon 4) . The available test data indicate that triethylamine salt of triclopyr is only slightly toxic to practically non-toxicto organisms tested. The compound is slightly toxic to ducks (LD 50 = 1698 mg/kg) and quail (LD 50 = 3000 mg/kg). Spring and fall applications may be necessary for effective control. Few products contain triclopyr as the only active ingredient. Triclopyr ester (0.75 to 1% solution) is the most effective formulation of triclopyr on thimbleberry and the other three species of wild blackberries.
