AIM-listed Plant Healthcare, which develops biological products for the global agriculture markets, has signed a deal with a second major industry player for the evaluation of its Innatus 3G peptide platform.The technology enables the design, screening and production of a large pipeline of peptides with diverse bio-stimulant properties, which can provide improved yields, pest and disease resistance, and protection against abiotic stress in a wide range of crops, the firm explained.Peptides can be combined with conventional crop protection chemicals in seed treatment and foliar applications, which makes them highly complementary to existing practices. Plant's chief, Paul Schmidt, said: "Our goal was to sign at least two evaluation agreements for our Innatus 3G peptide platform this year and we have accomplished that within the first five months."We are targeting the largest players and these agreements reflect the potential value they see in our platform. Our dialogue with other major players is on-going."
