In collaboration with State budgetary professional educational institution of Krasnodar krai “Brykhovetsky agrarny college” (stanitsa Brykhovetskaya, Krasnodar krai) our specialists have treated winter wheat with our biological products, designed for protecting plants against brown rust and cereal leaf beetles (oulema melanopus). Treatment results have shown biological products to be almost 100% effective and have revealed biological products to have a higher level of protection compared to chemical analogs.
