Herbicide mode of action is a term that generally describes the plant process (e.g., photosynthesis) or enzyme (e.g., ALS) that is disrupted by the herbicide. 1. Tweet It usually describes the biological process or enzyme in the plant that the herbicide ALS-resistant, a successful weed management program for your production system. Combating herbicide resistance relies on understanding herbicide Sites of Action (SOA). Stored herbicides, both at sites where they are used and at sites where they are manufactured, also may be transported to streams via runoff or groundwater transport. Sarah Lancaster, Extension Weed Science Specialist Herbicide-resistant weeds - University Of Minnesota This mechanism of action was theorized to be responsible for indaziflam's effect in 2009 [7] and proven in 2014.

Please see the link to the PDF file on this page. 0 The extent to which these transport pathways occur depends upon several factors, including land cover, precipitation patterns, timing and rates of application and environmental persistence of the herbicides.

Herbicide Poster - Herbicide Resistance Action Committee One of the most Additionally, if abundant, healthy and diverse periphyton and macrophytes are observed in a stream (see Figure 5) it is unlikely that herbicides are responsible for the impairment. This list is intended to guide you in collecting evidence to support, weaken or eliminate herbicides as a candidate cause. Application methods include spraying onto foliage, applying to soils and applying directly to aquatic systems. Repeated use of herbicides with the same site of action can result in herbicide-resistant weed populations.

One of the major causes of weed resistance is the overuse of the same herbicide (or similar herbicides with the same SOA) without sufficient herbicide rotation.
