Planting season is getting fully underway across the state, and with that we should all be getting our residual herbicides applied. Residuals are critical to successful season-long weed control as we have less documented herbicide resistance to these chemistries compared to postemergence products, as well as generally we see more consistent control from these herbicides because we’re targeting weeds before they’re even out of the ground. However, for residual herbicides to be successful, they require precipitation to be activated. I frequently get asked how much rainfall is required to fully activate these herbicides, how long can the herbicide wait until we’d receive this rainfall, and if a shallow tillage event would help the situation. These answers can be highly variable across herbicides (Tables 1 and 2), as they are normally dependent on water solubility and soil adsorption of the active ingredients; however, there are some general estimates that can be[Read More…]

What do you think of when you hear the word climate? I would guess answers would range from ‘average weather conditions’ to ‘hot, muggy summers’ to ‘climate change’ to ‘environmental policies and politics’.  What a range!  Fields of climate can vary from paleoclimate studies (e.g., ice cores and tree rings), to applied climate science (e.g., architectural design and vector-borne diseases like West Nile Virus and Malaria), to climate modeling (e.g., lots of physical equations and computers), to climate change (e.g., ‘but the polar bears, Daddy!’), to climate services (e.g., data translated into information). Among all this diversity, the common thread is the consideration and correlations of what has occurred in our atmosphere historically to better understand and prepare for current and future decisions. Since the late 1800s, our country has had an organized effort to collect observational data (e.g., temperature and precipitation) at hundreds of locations so we can monitor[Read More…]
