“…Therefore, the development of environmentally safe preparations able to enhance the action of commercial fungicides even at the minimum possible concentrations-as well as to reduce their selective pressure on pathogen populations accelerating the appearance and selection of resistant genotypes-is a very urgent and important task. One of the possible ways of its accomplishment is the use of biomethods based on the use of microorganisms or their metabolites possessing biocide activity or nontoxic organic or inorganic compounds, enhancing the sensitivity of target microorganisms to chemical fungicides [4,21].…”

“…The higher antifungal effect observed for a combined use of both compounds may be connected with the action of various components of the fungal biomass. Compounds enhancing the sensitivity of plant pathogens to fungicides attack methabolic pathways controlling the defense response of a microorganism to the oxidative stress, and also increase this stress provoking generation of toxic reactive oxygen species and disrupt cell and vacuolar membranes, which results in osmotic stress and apoptosis [4]. Therefore, DMP-caused homeostatic imbalance in microbial cells, together with the action of chemical fungicides may result in the maximal death of plant pathogens, even at minimal concentrations of active substances.…”

“…Under the current conditions of the intensive agriculture, crop cultivation strongly requires efficient disease control systems to prevent significant crop losses [1][2][3]. Among the most dangerous plant pathogens, pathogenic fungi take one of the leading positions [4,5].…”

“…Another promising approach to control crop diseases could include a combining of fungicides with biologically active compounds of microbial or plant origin, as well as with their synthesized analogues [20][21][22][23]. An antifungal effect resulting from the use of such combinations may be either additive, or synergistic; in the last case, synergistic interaction of both components makes it possible to significantly reduce effective concentrations of fungicide preparations until the levels, at which they would be inefficient if applied alone [4,10].…”

The developing resistance of plant pathogenic fungi to commercial fungicides has become a serious problem for efficient plant disease control. The use of antifungal preparations based on living microorganisms or their metabolites represents one of the possible environmentally friendly approaches. However, since a complete rejection of chemical fungicides is impossible, the combining of biopreparations and fungicides may be considered a promising biocontrol approach. Promising strains for the development of antifungal biopreparations include Penicillium fungi producing various biologically active compounds with antimicrobial and antiviral activities. A dry biomass of the P. chrysogenum F-24-28 strain (DMP) obtained from the P. chrysogenum VKPM F-1310 strain by induced mutagenesis possessed a high antifungal efficiency. According to in vitro experiments, supplementation of agarized medium with DMP (7.5–10 g/L) resulted in a significant growth inhibition in several plant pathogenic Fusarium fungi. The combination of DMP with a commercial azoxystrobin-based fungicide resulted in a prolonged growth inhibition in F. oxysporum, F. graminearum and F. culmorum even at fungicide concentrations significantly below the recommended level (0.5–2.5 mg/L or 2.5–12.5 g/ha vs. the recommended 100–275 g/ha). These results demonstrate a possibility to develop an efficient environmentally friendly biopreparation suitable to control crop diseases caused by a wide range of plant pathogens, and to prevent a possible selection and spreading of resistant pathogen strains.

“…Зафиксированы случаи возникновения резистентности почти против всех основных классов фунгицидов у самых разных видов фитопатогенов. Триазолы и стробилурины не являются исключением и согласно рейтингу Fungicide Resistance Action Committee (FRAC, https://www.frac.info/) риск резистентности к ним оценивают как средний и высокий [10]. Однако отказ от современных фунгицидов из группы высокого и среднего риска резистентности не представляется удачным с практической точки зрения.…”

The massive use of one-component fungicides has caused the problem of the emergence of resistant forms of phytopathogens. The development of multicomponent plant protection products is one of the ways of dealing with such a situation. The aim of the study is to determine the effectiveness of multicomponent chemical dressing agents in suppressing the most common fungal pathogens and seed infections in vitro. This work was performed in 2020 in the Federal Research Center for Biological Plant Protection (Krasnodar) in the laboratory of the creation of microbiological plant protection products and a collection of microorganisms. Fungi of the Fusarium, Microdochium, Bipolaris, Alternaria, Penicillium, Rhizoctonia, Septoria, Pyrenophora genera were used as test objects. The fungicidal activity of chemical preparations against economically significant phytopathogens causing root rot was evaluated in laboratory conditions by the method of serial dilutions followed by sowing on a nutrient medium. In addition, the effectiveness of the preparations was investigated by the method of treated seeds phytoexamination according to GOST 12044–93. The preparations, which included triazoles and phenylpyrroles, had the strongest inhibitory effect (100 %) on pathogens of Rhizoctonia, helminthosporiosis and septoria. The preparation containing compounds of the group of triazoles and strobilurins suppressed the growth of Rhizoctonia solani only. The preparations’ inhibitory effect on a number of phytopathogenic fungi was manifested in growth retardation, absence of aerial mycelium development and mycelium pigmentation. Concerning the causative agents of Fusarium root rot, the two-component preparations efficacy ranged from 51 % to 74.4 %; three-component one – from 42.9 % to 84.7 % depending on the species of the genus Fusarium. Presowing seed treatment made it possible to inhibit the growth of fungi of the genera Fusarium, Mucor, Aspergillus; significantly inhibit the development of the fungus Alternaria (spread in the experimental variant – 1.7 %, in the control variant – 46.7 %). From the data obtained, it can be concluded that multicomponent preparations based on triazoles and phenylpyrroles are highly effective in suppressing a wide range of phytopathogens and can be recommended for presowing seed treatment.
