Antagonistic potential of chemical fertilizers "FITOSPORIN – M" against the pathogens on common hyssop (Hyssopus officinalis L.)

Abstract

Data on the study and therapeutic prospects of Hyssopus officinalis L. as a valuable essential oil culture of the NBS are presented. The composition of infectious agents on hyssop was determined. Several variants of plant treatment with biological preparations were tested to identify the most effective way to protect hyssop from pathogens. The fungal pathogens Fusarium solani (Mart.) App. & Wr. were found on the culture of Hyssopus officinalis in the rhizosphere, the hyssop stem zone is affected by dry rot pathogens – Fusarium oxysporum Schltdl. Verticillium allbo-atrum Reinke & Berthold and V. dahlia Kleb were the dominant pathogens of Verticillium wilt on the top of the stem and on the leaves. The use of the biofungicide «Fitosporin – M» had a significant effectiveness against fungal pathogens on hyssop medicinal. Marked reduction in the degree of development of the disease from 24.1 % to 4.2 %. The number of spores in native preparations from extracts of tissues of infected plants of hyssop decreased in 15 times for the pathogens of Fusarium (F. solani), and 17 times for the agents of verticillata (V. allbo-atrum and V. dahliaе). High antagonistic activity in relation to pathogens of fungal diseases of Hyssopus officinalis was observed in the case of using a composition of two drugs. It was found that when the biofungicide «Fitosporin – M» and vitalizer «HB – 101» were used together, the number of spores of fungal pathogens fixed in the tissues of affected plants decreased to zero.
