New fungicide for powdery mildew in the pipeline

October 29, 2020  By Fruit and Vegetable

Gatten, a powdery mildew fungicide proposed for use in cherries, cucurbits and grapes, has been submitted to the Pest Management Regulatory Agency (PMRA) for registration which is anticipated in time for the 2022 growing season.

Delaware-based Nichino America and Ancaster-based Cohort Wholesale have reached an agreement for Cohort Wholesale to distribute new Gatten fungicide in Canada. Cohort established demonstration trials this past growing season in cherry and grape-growing regions of the country to support the introduction of the new fungicide.

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


In June 2020, the fungicide was registered for use on grapes in California. In March and April 2020, its label was expanded to be used for melon and cucumber/squash crops, and hops.

Nichino America is a wholly owned subsidiary of Nihon Nohyaku Co., Ltd., Japan’s first and oldest agrochemical manufacturing company.
