Summary. Zeroxxe is a new fungicide and bactericide product with a broad spectrum of activity against phytopathogenic fungi, oomycetes and bacteria. An active substance of Zeroxxe is silver nanoparticles superficially modified with environmentally safe biodegradable amphoteric surfactant. In vitro studies of Zeroxxe revealed its high efficacy against a wide range of fungal pathogens of potato: Rhizoctonia solani (bare patch), Phytophthora infestans (late blight), Colletotrichum coccodes (black dot), Helminthosporium solani (silver scurf), Alternaria solani and A. alternata (early blight), Fusarium solani (dry rot), Sclerotinia sclerotiorum (sclerotinia rot). To assess the bactericidal effect of Zeroxxe six types of pathogenic bacteria were tested: Pectobacterium carotovorum (soft rot of potatoes and vegetables), Dickeya dianthicola (black leg and soft rot of potato), Agrobacterium tumefaciens (bacteria cancer of fruit, ornamental plants and grapes), Xanthomonas vesicatoria (bacterial black spot of tomato), Clavibacter michiganensis (bacteria cancer of tomato and potato), Xanthomonas campestris (vascular bacteriosis of cabbage and rape). Incubation of bacteria in working solution of Zeroxxe (100 mg/l of silver) over 30 minutes completely inhibited the growth of colonies of test bacteria, 10 mg/l – inhibited 45…85 % of the colonies. The results show good prospects for using Zeroxxe as a fungicide for preplant treatment of various seeds and tubers, treatment of vegetating plants, as well as for the treatment of tuber and root crops before storage.
Keywords: fungicides, antibiotics, potato diseases, silver nanoparticles.
