Efficiency of effect of fungicides on causal organisms

Abstract

Aim. To of of learn the antibacterial operating of chemical facilities of defence on the causative agents of bacterial cancer and kpanchactictb plants of tomatoes (Lycopersicon of of of esculentum of of of Mill.). Methods. The of of phytopathogenic bacteria of of of C of of used. michiganensis subsp. michiganensis (Smith 1910) of of of Davis of of of et al. 1984 P. syringae pv. tomato (Okabe 1933) of of of Young of of of et al. 1978, isolates distinguished in the economies of the of of Dnepropetrovsk of of area and identified as of of X. vesicatoria and of of P. syringae pv. tomato. Antibacterial of of action of chemical facilities of defence, pesticides and agrochemicalss brought in to of of List of of and settled to application in of of Ukraine of of on tomatoes for limitation of development of phytopathogenic organisms, studied the method of small holes. Results. Found of of out antibacterial activity of preparations with the fungicide operating on the causative agents of bacterial cancer and black bacterial spotted. Conclusions. Found of of out antibacterial activity of preparations with the operating substances and by phosphorous acid for limitation of development of causative agents of bacterial cancer plants of tomatoes.
