BIUS ñ an Effective Agent for Increasing the Yield of Spring Wheat and Potatoes

A new efficient broad spectrum agent comparable in efficiency with chemical fungicides was developed on the basis of the aqueous solution of the salts of fir extract with bisamine, with the addition of the salt of 2,4-dichlorophenoxyacetic acid with bisamine and the Usnea lichen extract. The agent suppresses the development of fungal diseases and increases the yield of spring wheat and potato.
