Comments and limitations

DiFlexx Duo is a premix of Clarity 1.26 lb ae, Laudis 0.27 lb, and Bayer's CSA safener. DiFlexx Duo can be applied to field, silage, seed, and popcorn preplant, preemergence or postemergence on corn up through V7 or 36 inches tall, whichever comes first. It can be applied with a directed spray on 7 to 10 collar corn up to 36 inches tall. DiFlexx Duo applied sequentially, two applications only, must be separated by a minimum of two weeks and must not exceed a total of 78 fl oz. Use MSO or COC at 1% v/v when applied alone or tank mixed with atrazine. When Liberty 280 is the tank gallon of spray solution or 1.5 lb AMS/acre. The use of 1.5 qt/a of UAN or 8.5 to 17 lbs AMS/100 gallons spray solution with DiFlexx Duo will improve weed control when applied in conditions of low humidity. The addition of AMS to a spray mixture containing dicamba will increase the risk of volatility of dicamba and mitigate the benefits of lower volatility of products like Clarity or DiFlexx.

The Pesticide Selector includes suggestions for chemical control of pests in Kansas crops, which are provided by K-State Research and Extension, and may not be relevant for states other than Kansas. We will continue to expand this tool for help in selecting other types of agricultural chemicals, and for other states. Contact the myFields Team if you are interested in contributing content!
