This post links to lists of fungicides labeled for use on Mississippi grown peanuts as of February, 2014. Each document sorts the same information different ways.

These references have many uses:

  • What if you have been using the fungicide “Onset” but your supplier does not have any in stock? You can look up “Onset” in the “byTrade_Name” and find that the active ingredient is tebuconazole. You can then use the “byActive_Ingredient” list to find other products that have tebuconazole in them. One choice would be Muscle.
  • Say that you want to use a tebuconazole fungicide on your peanuts. You could use the “byActive_Ingredient” reference to find all the fungicides that have tebuconazole as their major ingredient.
  • Except for chlorothalonil (sold as Bravo, Echo…), and mancozeb (sold as Dithane, Koverall…) most fungicides kill fungi by a single mode of action. Each mode of action has been given a number, called a FRAC Code.

To avoid the fungi developing resistance to fungicides, you should rotate the FRAC codes. There are three common groups of fungicides labeled for use on peanuts, 3, 7, and 11. Each of these kills the fungus one way, but a different way for each number. Fungicides which kill fungi multiple ways, begin with an “M”. You can use the “byFRAC_Code” to find some rotation products.

New this year:

Based on your suggestions, this year I have added some additional information on the products. Included is the post-harvest interval, rotation restrictions, and whether the product can be used in-furrow or at emergence (for stem rot control).

The first document lists the fungicides by Trade Name. The second lists the fungicides by Active Ingredient, the third by FRAC code (Fungicide Resistance Action Committee code) whereas the fourth link incorporates all three into a single pdf. All documents are available in either PDF or a spread sheet format. The format is LibreOffice or Open Office. They are a free download (www.libreoffice.org).
