Each year I get a lot of questions about chemical tank mixes for peanuts. The main problem with this is that there are thousands of possible tank mixes when you consider all the herbicides, fungicides, fertilizers, and insecticides. It would take years of research to test all of them. But we do know a lot about tank mixes which has been published by our extension research scientist. Follow link below to access Tank Mixing Chemicals Applied to Peanut Crops. This list may not have some of the newer fungicides, but hopefully it will help you with some basic tank mix combinations. It will be best to print the document for better observation.
