The efficiency of using silicon-containing mixture to improve the stability of roses to infection with powdery mildew pathogen Sphaerotheca pannosa Lev. var. rosea Woron.

According to the modern demands of regulated use of chemical plant protection under the laws of Ukraine “On ensuring sanitary and epidemiological welfare of population”, “On Pesticides and Agrochemicals” and “On Plant Protection” in M.M. Gryshko National Botanical Garden of the NAS of Ukraine protective measures against diseases aimed at regulating the density in a agrocenoses, control distribution, intensity of development and harmfulness of pathogens. We carried out a three-year study of influence a silicon-containing mixture on ability to live plant roses and intensity of development powdery mildew causes pathogen (Sphaеrotheca pannosа Lev. var. rosea Woron.). Founded positive influence this mixure on forming resistance roses variety Tornado (KORtor) from group Floribunda to infection of powdery mildew and compared its higher efficiency with the use of chemical plant protection. In the version using silicon-containing mixture was recorded the lowest level of destruction plants. It has been traced prolonged impact of this mixture on roses. It has been proved the rationality to use its in agrotechnics growing roses. It has been recommended the applying of this mineral recommended in quantity of 50 g/m².
