Visalia, California, March 3, 2026 Sym-Agro Inc. and Biofungitek SL announced today that the parties have entered into a US distribution agreement for Biofungitek’s new fungicide, Berezi®
Berezi represents a new mode of action for the control of Powdery mildew, Botrytis and other diseases of fruit and vegetable crops. The patented technology combines the two active ingredients Potassium Carbonate and Thyme Oil which interact synergistically. Berezi is EPA approved and CDPR registered for use in California and Western US States
Berezi is an innovation for this active ingredient, utilizing potassium carbonate instead of potassium bicarbonate eliminating the issues of visual residue and greatly reducing the phytotoxic potential compared to current standard potassium bicarbonate fungicides. The addition of Thyme oil brings an additional mode of action which leverages the effects on fungal cell susceptibility, potentially lowering use rates. Growers will appreciate the improved mixing/loading attributes as Berezi easily goes into solution and won’t settle out in the spray tank
Peter Bierma, President, Sym-Agro stated – “This innovative formulation combining a proven technology with an essential oil creates a powerful new biochemical solution for growers. It aligns well with our suite of products to provide exceptional disease control in high value cropping systems. Growers will appreciate this new effective fungicide option to add to their toolbox this coming season”.
