Using multiple effective SOAs helps growers to better manage weeds. It also prevents weeds from going to seed, limiting their impact the following year and minimizing unmanaged weeds being harvested with the crop. Type of Herbicide Not all herbicides contain the sites of action (SOAs) that will be effective against the weeds present in your fields. Herbicides have different active ingredients that target different weed species. For instance, many generic premixes contain an active ingredient called metolachlor, an older and less potent version of S-metolachlor. The metolachlor rate in many of these generics has to be 1.5 times higher than the S-metolachlor rate in Syngenta premixes in order to provide a similar level of control. These subtle differences can have a major impact on weed control. 4 Use Rate Experts recommend always using the full, labeled rate of a herbicide. An Iowa State University study found that reduced rates may be adequate against a flush of early- season weeds, but the residual control is greatly reduced, potentially creating problems later in the growing season. Syngenta Research and Development Scientist Joe Wuerffel says using a three-quarter or half-rate essentially guarantees having to follow up with a post-emergence application. Use of reduced rates could also lead to yield loss, as well as contribute to the development of resistant weeds. 5 BONUS
