STK Aqua

STK Aqua develops and commercializes botanical-based, food protection solutions that solve the myriad challenges of modern fish farming. From vaccination, transportation and stress reduction through staving off the onslaught of parasites and bacterial diseases, STK’s chemical-free formulations are a real game-changer in this space.

Demand for fish, shrimp and other aquatic species has never been greater – and the ecosystems where they thrive have never been in greater peril. STK Aqua enables the complete replacement of chemical treatment with botanical-based solutions that effectively reduce disease, infection and mortality, while safeguarding natural habitats.

Fish consumption has almost doubled since the 1960s. With the global population forecasted to grow to 9.7 billion by 2050, farm fish is steadily becoming an increasingly critical food category in supplying the world’s protein needs. Nearly half of the seafood destined for human consumption is produced today through the auspices of fish farming, also known as aquaculture.

Farmed fish are typically crowded together in net pens or cages anchored to the sea floor in the ocean near the coast. Subsequently, these fish are exposed to high tense stress, which can foster disease and parasites. The chemical solutions traditionally used to address these challenges leave poisonous residue which harm fish raised for human consumption. Moreover, they pollute aquafarming environments and the surrounding waters.

STK Aqua is devoted to solving the complex challenges facing modern sustainable aquaculture. Our formulations are extensively tested and proven in clinical and field tests by our Research and Development Innovation Center.

STK Aqua offers a range of do-no-harm botanical solutions that previously did not exist in the market for improving the daily management of fish, helping to increase their survival rate and enabling safer, healthier and more abundant production.

STK REGEV® ‘Hybrid’ fungicide, now registered in Argentina!

September 10th, 2018 (Petach Tikva, Israel) – STK bio-ag technologies, the innovative Israeli-based leader in bio-ag technologies for sustainable crop protection and aquaculture, is announcing that its ‘hybrid’ fungicide STK REGEV® is now registered in Argentina for peanuts, with future label extensions on potatoes, wine grapes, tomatoes, peppers, blueberries and tobacco. STK REGEV® protects and heals a variety of diseases, including Cercospora Arachidicola (early leaf spot), Cercosporidium Personatum (late leaf spot) for peanuts, Powdery mildew, Alternaria, Rust and Botritis for other crops. STK REGEV® is the world first foliar ‘hybrid’ fungicide, and is currently used successfully in ten countries in various regions of the world, with plans for global expansion in 2019. STK REGEV® is a ready to use fungicide, used exactly as other fungicides, but with the added benefits of reduced chemical residues and much better resistance management due to its highly complex formulation of Tea Tree Oil and Difenoconazole. This ready to use fungicide serves as a ‘bridge’, enabling farmers who have never used any biological product to try one, without having to mix, rotate or do anything different, thereby expanding the use of biologicals products for sustainable agriculture. Field test data has shown STK REGEV® performs as well or better than solo chemical leader market fungicides. Only with REGEV®, farmers will realize all the benefits of lower chemical load, reduced chemical residues and having a new tool for resistance management. According to STK Argentina’s country manager Mariano Laurencena, STK REGEV® is going to be distributed exclusively by SummitAgro. STK is also happy to answer questions directly on TIMOREX GOLD®, STK’s botanical-based bio fungicide, which Argentinean and other farmers throughout Latin America have been using with great success for many years on about 15 different crops.
