Columbia, MD, March 30, 2020ManKocide®, a leading fungicide/bactericide for control of Alternaria, powdery mildew and blight has been approved for use on all tree nut crops by the California Department of Pesticide Regulation. CDPR announced the approval on March 25, 2020, making ManKocide® available to California tree nut growers for the current growing season.

ManKocide® is a mancozeb plus copper hydroxide fungicide-bactericide formulation that is trusted for its consistent reliability in controlling diseases in vegetables, fruit and tree crops. Previously approved for use in California for a variety of crops, the CDPR announcement expands the label to include use on tree nuts such as almonds and walnuts.

“As part of our Kocide® portfolio of copper products, ManKocide®  delivers a technologically-advanced and trusted formulation from the combination of two disease fighting active ingredients,” says Mike Allan, Certis USA Vice-President, North America. “Growers across California and the United States can now rely upon the power of ManKocide® for the control of diseases such as walnut blight and bacterial spot. We are proud to offer California’s tree nut producers a trusted product to enhance the success of their farms.”

ManKocide® is a unique dry, flowable formulation of copper hydroxide and mancozeb that provides maximum protection in one convenient product. Its dual mode of action maximizes disease protection while minimizing the potential for disease resistance.

Growers find the product’s dry formulation, which handles and pours “like a liquid”, is easy to measure, mix and spray. It can be successfully tank-mixed with most fungicides, insecticides and foliar fertilizers and can be applied by air, ground and chemigation.

California tree nut producers who are interested in integrating ManKocide®  into their treatment schedules for 2020 are encouraged to contact their local retailer, distributor or Certis sales representative. Growers new to the Certis portfolio of brands should visit to inquire about ManKocide® and other biopesticide solutions.
