Chemical selector
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!

Crop type: Corn
Application type: Postemergence
DiFlexx Herbicide Duo is a premix of Clarity 1.26 lb ae, Laudis Herbicide 0.27 lb, and Bayer's CSA safener. DiFlexx Herbicide 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 Herbicide 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 SL 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 Herbicide 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 Herbicide.
DiFlexx Herbicide is a premix of Clarity and Bayers CSA safener. DiFlexx Herbicide can be applied to all corn types from spike through the 6 collar growth stage; and directed spray through the 10 collars growth stage, or 36 inches tall, or 15 days prior to tassel, whichever comes first. The use of NIS at 0.25% v/v, COC or MSO at 1% v/v, and a nitrogen source UAN at 2 to 4 qt/acre or AMS 8.5 to 17 lb/100 gal will enhance postemergence activity on emerged weeds. For the best control, apply to weeds that are less than 3 inches tall. The addition of AMS to a spray mixture containing DiFlexx Herbicide will increase the risk of volatility of dicamba and mitigate the benefits of lower volatility of DiFlexx Herbicide.
