LIBERTYVILLE, Ill.--(BUSINESS WIRE)--Valent BioSciences LLC and Seipasa announced today the formation of a strategic partnership to advance biostimulant technology offerings to the U.S. agricultural market.

Seipasa, a pioneer in the development, formulation, and production of biopesticides, biostimulants, and nutritional products used in agriculture, has named Valent BioSciences its exclusive partner for the commercialization of novel biostimulant products in the U.S.

Under this agreement, Valent BioSciences will bring yet another unique biostimulant solution to the U.S. market. Seipasa’s new biostimulant, Sweetsei™, is a revolutionary biostimulant designed with an optimized biochemical matrix that influences key plant pathways to improve quality parameters in specialty crops.

“We are excited to enter this strategic partnership with a globally recognized research and development company. Seipasa brings a scientific rigor to the biostimulant market that complements our own scientific standards,” says Salman Mir, President and CEO of Valent BioSciences. “And Sweetsei is a proven technology that will help farmers optimize their harvest.”

“The United States is a key market in our international expansion,” said Pedro Peleato, CEO of Seipasa. "Sweetsei is a biostimulant with extensive international reach that is already present, with proven results, in markets across Latin America, Europe, and Africa. It is very exciting to be partnering with Valent BioSciences to bring our biostimulant solutions to farmers.”

In 2022, Valent BioSciences unveiled its dedicated business team focused on bringing biostimulant solutions to U.S. farmers. In early 2023, the acquisition of FBSciences further strengthened the offering to the agriculture market with its Transit^® biostimulant product line.
