    FRAC launches new website

    We are excited to bring you the new FRAC Website!  It has a very similar look and feel to the previous version but brings key information to the webpages themselves for easy reference. Some of the key changes are:

    1. The 2015 Use Recommendations are found by crop under the General Use Recommendations tab within each Working Group.  The entire pdf containing the previous year's monitoring results and the current year's use recommendations can still be found at the bottom of the General Use Recommendations page.
    2. We've included a Resistance Overview Section for people who are new to the science of fungicide resistance and its management.  For more information, our 3 monographs can still be found under the Publications tab.
    3. Information on the MOA Expert Panel and how active ingredients get included in the FRAC Code List has been included.
    4. The Benzimidazole Expert Fora has been updated.
    5. A new search feature to find pertinent information is now located at the top right of each page. 

    For comments or suggestions, please contact Lisa Hoffman.

    FRAC Code List and FRAC Mode of Action Poster updated

    Both the FRAC Code List and the FRAC Mode of Action Poster were updated in January, 2015. Three new compounds were included in the list.

    1.  Dimethaclone was added to the dicarboximides (E3: Map/Histidine-Kinase in osmotic signal transduction; FRAC Code number 2).  

    2.  A new group within melanin biosynthesis was created for tolprocarb  (I3: polyketide synthase in melanin biosynthesis; FRAC Code number 16.3).  
    3.  A new unknown group was created for picarbutrazox (FRAC Code number U17).

    The FRAC Mode of Action Poster was also updated to reflect these additions.
