Herbicides are applied to forests after harvesting to suppress brush and noncommercial trees. Summary of Herbicide Mechanism of Action According to WSSA Several herbicides have been identified as having an unknown mode of action including organic arsenicals (Group 17), arylaminopropionic acids (Group 25), and other non-classified herbicides (Group 26). PostScript For instance, tanking mixing two herbicides with different SOA, but only one of the herbicides will kill the weed, there is only one effective SOA. The bioavailability, uptake and toxicity of herbicides vary with environmental conditions (e.g., pH). Refer to the Mode of Action chart for more . The publication is divided into the following topic areas: Understanding how herbicides work provides insight into how to use the chemicals and helps diagnose causes of poor weed control or crop injury. 0 0 All crop protection products must be handled and applied strictly as specified on the product label or APVMA permits. The Mode of Action classification for herbicides is being changed in Australia. Anthropogenic activities and sources can supply streams with high concentrations of herbicides and their metabolites, which can lead to lethal and sub-lethal effects on aquatic biota (see Figure 6).
