“…In recent years, biopesticides are recognized as a viable alternative to control pests and as a possible substitute for the traditional chemical used [1,2]. Already, it exists a high number of studies focused on the selection of microorganisms to inhibit and even kill pests, the evaluation of effectiveness against pests, the mechanisms of action, the production systems and the viability [3,4].…”

In recent years, the production of biopesticides has gained great attention in the scientific word because it is an important alternative to replace the much debated chemical pesticides used on the field crops. Fungal lytic enzymes, conidia and secondary metabolites like 6 pentyl-alpha-pyrone (6-PP) play a very important role in the biological control of pests. On the present study, the influence of application of air through a solid-state fermentation using three Trichoderma asperellum strains to produce conidia, 6-PP and essential enzymes were evaluated. A mix of vine shoots, potatoes flour, jatropha, olive pomace and olive oil as substrates was used. T. asperellum TV104 showed the best 6-PP production (3.06 ± 0.15 mg g DM −1), cellulases activities (34.3 ± 0.4 U g −1), and amylase activity (46.3 ± 0.6 U g −1) however, T. asperellum TF1 produced the higher levels of lipase (30.6 ± 0.3 U g −1), under air conditions. The production of these same enzymes was less efficient without the application of forced aeration. The forced aeration increased the conidia production, the best value was observed with T. asperellum TF1 (2.23 ± 0.07 × 10 9 g DM −1).

“…state of increased resistance to a spectrum of harmful organisms (López- Bucio et al, 2015). Metarhizium anisopliae species represents an effective prevention of damage to germinating and emerging plants caused by soil insect pests (Miranda-Hernández et al, 2016). Both beneficial fungi, T. virens and M. anisopliae, are preventively introduced into soil with seeds as they induce suppression of the fungal disease agents or soil pests in the sown crops.…”

This work deals with the possibility of elimination of common occuring mycotoxins deoxynivalenol (DON) and its plant metabolite deoxynivalenol-3-glucoside (D3G) from malting barley and malt by treatment of low-temperature plasma discharge. Barley seed was treated with a fungicide, entomopathogenic and mycoparasitic fungi and the low-temperature plasma discharge of Gliding Arc type, or their combination. Samples of harvested barley were treated with plasma discharge and analyzed for presence of mycotoxins. Only low DON and D3G concentration levels were detected (maximal values were 48.2 µg/kg and 30.2 µg/kg for DON and D3G, resp.), after plasma treatment mycotoxin content decreased onto the levels near limit of quantification. The results suggest that low-temperature Gliding Arc plasma discharge may contribute to reduction of the content of the mycotoxins in harvested barley grains.

Despite the urgent need for alternatives to chemicals in plant protection, biological herbicides are not widely used as biofungicides and bioinsecticides. The review is devoted to connections between fungal biology, biochemistry, their ability to survive in extreme environment and development of effective mycoherbicides. Advanced studies on the production and stabilization of mycofungicides and mycoinsecticides were analyzed too in order to obtain ideas for the improvement of efficacy and technology of mycoherbicides in the future. The analysis of research data published within last 20 years showed following trends. First, more attention is paid for production both effective and stress tolerant propagules especially based on the submerged fungal mycelium and its modifications (blastospores, chlamydospores and microsclerotia). Second, the construction of bioreactors, in particular, for solid-state fermentation is continuously being improved that allows producing highly stress tolerant fungal aerial conidia. Third, based on studies of biochemical mechanisms of viability of fungi in extreme environment, the approaches of stabilization and storage of fungal propagules were developed. However, the positive reply to the question, if biopesticides including mycoherbicides, will become a serious alternative to agrochemicals, will be possible when they demonstrate stable efficacy in the field conditions and safety for both environment and end users.
