Nearly all herbicide labels (soil-applied or postemergence) have rotational crop intervals that specify the amount of time that must elapse between herbicide application and planting a rotational crop.  This becomes particularly important with late-season herbicide applications, and when soil moisture is limited. Additionally, the labels of almost all postemergence soybean herbicides indicate a preharvest interval or a soybean developmental stage beyond which applications cannot be made.  Labels of some products may indicate both a developmental stage (before soybean bloom,…

Soil-residual herbicides are important components of integrated weed management programs. Labels of many single and multiple active ingredient products allow application before and after soybean emergence, but other active ingredients can cause severe soybean injury if applied to emerging soybean. In fields where a PRE herbicide application has been delayed and soybean are beginning to emerge, the following active ingredients (applied either alone or as a premix product) should not be applied:
sulfentrazone (many Authority-based products,…

The Illinois Department of Agriculture recently announced additional restrictions for dicamba applications to soybean. In addition to the requirements of the federally-approved labels, all use on soybean of pesticides containing dicamba in Illinois shall comply with the following requirements:
Temperature Restriction: A pesticide containing dicamba shall not be applied on soybean if the air temperature at the field at the time of application is over 85 degrees Fahrenheit or if the National Weather Service’s forecasted high temperature for the nearest available location for the day of application exceeds 85 degrees Fahrenheit.…

In late October 2020, the United States Environmental Protection Agency (US EPA) announced new five-year registrations for the dicamba-containing products XtendiMax, Engenia and Tavium.  These labels include new and/or additional application restrictions that were not included on previous labels.  Annual dicamba-specific training (which we hope begins soon) offered by the product registrants will undoubtedly cover many/all of the new label changes, but there are a few changes that some currently might not be aware of and might come as a bit of a surprise. …
