Tank mix demonstrations have impact on Kentucky Farmers

Tank mixing of herbicide is a common practice to capture control of a broad spectrum of weed species within a field and has become more common over the past year with a decrease in availability of broad-spectrum herbicides.  Tank mixing of herbicides can also come with pitfall such as physical compatibility leading to products falling out of solution as participants or gel and not being able to be effectively applied with a sprayer.   Tank mixing can also lead to antagonism in which the effectiveness of one herbicide is reduced by a tank mix partner.   Understanding the proper sequence to mix herbicides and what herbicide mixes should be avoided are important aspects of weed control that are often not discussed.   I developed a tank mix and adjuvant talk that was first presented at the 2021 Spray Clinic and have since been asked to present the talk at several counties.  In Webster County in February 2022 a farmer approached me following the talk and said he had been spraying for 20 years and this was the first time anybody had every told him the proper way to mix herbicide and why its important.   It is often assumed that farmers know all these fine details, but all to often that assumption is incorrect as I found out in this case.  This talk will continue to be a primary part of my message in the future.
