Technology offer : Use of 4-phenylbutyric acid (4PBA) to improve plant tolerance to bioagressors

Technology's description

4-phenylbutyric acid (4PBA), or one of its salts, can be used to improve plant resistance to phytopathogen  among bacteria, virus and nematodes, and as antimicrobial agent to prevent or treat plant disease.

4PBA can be applied usind an aqueous solution, on seeds, soils, on aerial parts the plant, roots, and on the harvested material to guaranty better storage.

Tests shown that bacterial (Xanthomonas) growth was divided by 7 on coton after treatment with 4PBA.
