Gatten CA Fungicide: A New Mode of Action for Control of Powdery Mildew in Grapes Now Registered in California

Wilmington, Delaware (June 15, 2020)--Gatten CA, a unique mode-of-action fungicide marketed by Nichino America, is now registered for use in grapes in the state of California, the company announced today.

 

This product brings a much-needed alternative chemistry for control of powdery mildew in grapes as well as apples and cherries. Gatten CA is a FRAC Group U13 fungicide that has shown no cross resistance with existing fungicides. Gatten CA has demonstrated a high level of efficacy similar to or better than that of current fungicides. This makes Gatten CA an ideal rotational tool for resistance management programs.

The active ingredient in Gatten CA, flutianil, works by inhibiting the formation of the haustorium which is the structure the fungus uses to extract water and nutrient from plant cells. It also inhibits secondary hyphal extension, stopping growth of existing infections. Additionally, Gatten CA has translaminar movement which provides protection to both sides of the leaf and improves control, especially when foliage is dense.

For grapes, Gatten CA should be applied using 6.4 fluid ounces per acre. The label for Gatten CA states a 12-hour REI, and there is a 14-day PHI. Always read and follow all use directions.

MRLs exist for registered crops for many major export countries; refer to the global MRL database for current established tolerances www.globalmrl.com/db#query.
