Potential Applications

RNAi has emerged as a promising tool for targeting agricultural pests and pathogens and could provide an environmentally friendly alternative to traditional means of control. However, the deployment of this technology is still limited by a lack of suitable exogenous- or externally applied delivery mechanisms. Numerous means of overcoming this limitation are being explored. One such method, bacterium-mediated RNA interference, or bmRNAi, has been explored in other systems and shows great potential for application to agriculture. Here, we review the current state of bmRNAi, examine the technical limitations and possible improvements, and discuss its potential applications in crop protection.

The latest trend in agriculture is the development and application of environmentally friendly pesticides with targeted and controlled release of active ingredients embedded in biodegradable polymer bases. In this work, a series of experimental slow-release pesticide formulations was produced using composites of degradable polyester poly(3-hydroxybutyrate) and natural materials as a matrix for embedding two agrochemicals – a fungicide (tebuconazole) and an herbicide (metribuzin). The structure, physicochemical properties and degradation rate of long-term formulations and the kinetics of active ingredient release from the matrix were studied in laboratory soil microecosystems. The experimental formulations allowed for a gradual release of agrochemicals into the soil for two months without abrupt emissions, providing long-term plant protection against pathogens and weeds. In contrast to the free forms of the agrochemicals, the analysis showed an absence of noticeable shifts and negative impacts on soil bacterial communities with the introduction of the developed formulations. The fungicidal action of long-term tebuconazole was confirmed on model Triticum aestivum plants infected with a complex of root rot pathogens (Alternaria, Fusarium, and Bipolaris). The efficacy of embedded metribuzin on model Melilotus albus weeds was comparable to that of the free forms of this herbicide. This work has produced new data on biodegradable polyhydroxyalkanoates for constructing long-term formulations of agropreparations. The fundamentals have been provided for constructing environmentally friendly and targeted controlled-release formulations of crop protection products against pathogens and weeds

Antifungal Efficiency

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.

The depletion of phosphate rock reserves has led to the search for new, alternative and environmentally friendly products and processes. One of the safe and environmentally friendly sources of phosphate is animal bone char (ABC), the residue from the pyrolysis of meat and bone meal (MBM), a slaughterhouse waste material. The presented study investigated the physico-chemical properties of the residues (ABC) obtained from the pyrolysis of MBM under different treatment conditions. Two different end temperatures (600 °C and 1000 °C) and five different heating rates (5 °C min−1, 10 °C min−1, 20 °C min−1, 50 °C min−1 and 100 °C min−1) were used. The ABC samples obtained were characterised by X-ray powder diffraction, IR spectroscopy, elemental CHNS analysis and SEM/EDS analysis. The results showed the strong influence of both the pyrolysis end temperature and the heating rate on the morphology and chemical composition of the final products.
