July 2017

Stockton STK, a leading biotechnology company specializing in the development and marketing of botanical-based solutions, and Seipasa S.A., a pioneer company engaged in natural treatments for zero residues agriculture, announced today that the companies have entered a long-term partnership in the United States for exclusive distribution and co-development on the patented strain of Bacillus subtilis, a rhizosphere bacterium that quickly establishes beneficial colonies on the plant’s roots and leaves.

The unique strain of Bacillus subtilis protects crops from foliar and soil diseases by preventing their access to roots and plant surfaces, by disrupting pathogen development and by inducing SAR (systemic acquired resistance) in treated plants.

Under the terms of the agreement, the product will be manufactured and supplied by Seipasa S.A. and marketed and distributed in the U.S. by Stockton STK under the Stockton brand AVIV ™. Stockton and Seipasa, supported by their R&D departments, will develop new uses for this product while the agreement is in force.

“We are very pleased to enter into this collaboration with Seipasa S.A., a true partner for the long run. This agreement reflects Stockton’s increased commitment to a more holistic approach to sustainable crop protection in modern agriculture,” said Guy Elitzur, CEO of Stockton. “This collaboration is extremely attractive for us and represents an ideal addition to our portfolio, which will pave the way into the U.S. market”

“Seipasa takes pride in providing its expertise and deep knowledge to this project”, claimed Pedro Peleato, CEO of SEIPASA. “This is an enduring agreement in which, in addition to multiple synergies, there are two elements ensuring success: the strength of Stockton’s commercial platform and the quality of a first-class product in the market”. “Seipasa shares Stockton’s mindset, so this alliance absolutely reflects the confidence we have in our partner”, said Pedro Peleato.
