GENERAL FACT SHEET TRICLOPYR National Pesticide Information Center 1.800.858.7378 4 Can triclopyr affect fish or other wildlife Triclopyr is practically non-toxic to slightly toxic to birds. The mechanism of action for HPPD inhibitors was misunderstood for the first twenty years that these products were sold, starting in 1980. MOA Common Name WSSA Code ... triclopyr 4 O POST Confront Dihydropteroate Auxin and Auxinic Herbicide Mechanism(s) of Action - Part 1 - Introduction. From woody plants to annual and perennial weeds, Alligare Triclopyr 3 Herbicide provides an effective mode of action for targeting bothersome blackberry, Canada thistle, ragweed and wild lettuce. Triclopyr was initially registered with the EPA in 1979 and was reregistered in 1997. The active ingredient triethylamine salt (3,5,6-trichloro-2-pyridinyloxyacetic acid), commonly called triclopyr, is the formulation registered for use in aquatic systems. Triclopyr is an herbicide used to control woody plants and many broadleaf weeds including rights-of-way, industrial areas, forestry, railways, rangeland, home lawns, and permanent grass pastures, rice, turf, and plantation crops such as palm oil. The term "mode of action" refers to the sequence of events from absorption into plants to plant death, or, in other words, how an herbicide works to injure or kill the plant. It also kills other weed pests such as dandelion, poison ivy and chicory. They were originally thought to be inhibitors of protoporphyrinogen oxidase (protox).. 4-Hydroxyphenylpyruvate dioxygenase (HPPD) is an enzyme found in both plants and animals which catalyzes the catabolism of the amino acid tyrosine. 5 Long-term exposures to birds (acid form) may affect eggshell thickness.4 While the salt form is practically non-toxic to slightly toxic to shellfish, the ester form is moderately to Submitted to: Paul Mistretta, COR. 4 2 9 5 14 HERBICIDE CLASSIFICATION byACTION MODE OF (effect on plant growth) This chart groups herbicides by their modes of action to assist you by PREMIX in selecting herbicides 1) to maintain greater diversity in herbicide use and 2) to rotate among effective herbicides with different sites of action to delay the development of herbicide resistance. SERA TR-052-25-03c . Alligare Triclopyr 3 Herbicide Target Weeds. At low doses, dicamba has similar hormonal properties to natural auxins. 7 High concentrations of dicamba in plant tissues induces abnormal and uncontrollable growth, disrupting normal plant functions, resulting in death.

Tracy M. Sterling, Department of Entomology, Plant Pathology and Weed Science at New Mexico State University ; Deana Namuth, Department of Agronomy and Horticulture, University of Nebraska-Lincoln The current knowledge of the mode of action followed by auxins can give clues to determining the characterization of the kind of resistance occurring in the field. Authors. Auxinic herbicide resistance can be induced in two areas: one in plasma membrane and the other in transcription ARFs. CC. Triclopyr acid has different formulations for aquatic and terrestrial use. The specific site the herbicide affects is referred to as the "site or mechanism of action."
