“…These findings could be explained due to the effect of the efficient microorganisms on plant growth in different ways, for example throughout the production of phytohormones such as auxin and cytokine-like compounds (Berger et al, 2015;Nghia et al, 2017), the solubilization of minerals such as phosphate and nitrogen (Changas-Junior et al, 2015) and indirectly by the production of substances with antibiotic activity which reduce the number of phytopathogen microorganisms (Grosu et al, 2015). Moreover, when EM interact with the organic matter, other beneficial compounds are also released, such as vitamins, organic acids, minerals, and antioxidants (IICA, 2013).…”

The aim of this work was to evaluate the effect of the application of efficient microorganisms (EM) on the productive performance of lettuce and radish. The experiment was carried out in an organoponic culture in the municipality of Matanzas, Cuba, from December 2017 to January 2018. Five treatments were studied: control (0), EM 8 mL m-2 at 0 days after the transplant (DAT) (EM 8-0), EM 8 mL m-2 at 15 DAT (EM 8-15), EM 10 mL m-2 at 0 DAT (EM 10-0), and EM 10 mL m-2 at 15 DAT (EM 10-15). A randomized complete block design was set with four replications per treatment. An ANOVA was applied to perform the statistical data analysis, and the Duncan’s Multiple Range Test (P<0.05) was used for the comparison of means. The statistic program used was STATISTICA, version 6.0 over Windows. The parameters evaluated in lettuce were the total number of leaves, number of commercial leaves, the diameter of leaf rosette, and yield. The evaluated parameters for radish were fleshy root’s diameter and weight, and yield. The results indicated a positive effect on growth-response with the application of the bio-product, which can be considered a promissory alternative for vegetable production in organoponic garden conditions. The application of EM 10 mL m-2 at 0 and 15 DAT showed the best productive behavior for both crops.

“…Fusarium fungi attract attention of numerous researchers [25,33]. Representatives of this genus included in this study (F. oxysporum, F. graminearum, F. culmorum and F. avenaceum) are very common pathogens infecting wheat, rye, barley, oats and many other crops [15].…”

“…The majority of these fungi are able to produce highly toxic metabolites (mycotoxins), such as deoxinivalenol, zearalenone, etc., belonging to different groups of chemical compounds. As a rule, fusariotoxins represent chemically stable compounds that are able to be kept unchanged for a long time in plant-derived food and feed [24,25].…”

Antifungal Activity of the Dry Biomass of Penicillium chrysogenum F-24-28 and Is Application in Combination with Azoxystrobin for Efficient Crop Protection

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.

“…Insects feeding on developing kernels inject salivary hydrolytic enzymes that break down gluten to reduce bread quality (Hosseininaveh et al 2009;Koksel et al 2009). Fungal diseasesnamely root and crown rot caused by F. culmorumthreaten wheat production in different areas of the world (Grosu et al 2015;Meyer-Wolfarth et al 2017). Fusarium culmorum symptoms appear as brown necrotic discolouration, root browning, and necrosis, resulting in stand loss, reduced yield, and decreased grain quality.…”

Effects of endophytism by Beauveria bassiana (Cordycipitaceae) on plant growth, Fusarium (Nectriaceae) disease, and Sunn pest Eurygaster integriceps (Hemiptera: Scutelleridae) in wheat (Poaceae)

et al. 2023

Fungi living within a plant (i.e., endophytic fungi) can directly affect the growth of the host plant or have indirect effects by affecting levels of damage to the plant caused by insect herbivory or plant pathogens. Greenhouse and field trials were conducted to investigate the endophytic effects of the fungus Beauveria bassiana on wheat, on the wheat-feeding Sunn pest, Eurygaster integriceps (Hemiptera: Scutelleridae), and on the wheat pathogen, Fusarium culmorum (Nectriaceae), which causes root and crown rot disease. Conidia of B. bassiana were applied to wheat either by foliar spray, soil drench, or seed treatment. Seed treatment with conidia provided the highest re-isolation percentages: 91.7% in leaves, 95.8% in stems, and 91.7% in roots. Inoculated plants were taller and had greater wet and dry weights compared to control plants. In both greenhouse and field studies, E. integriceps that were fed inoculated plants laid eggs that were less likely to hatch. Inoculations reduced the incidence of root and crown rot disease by 42% under greenhouse conditions. These results document the potential of using endophytic infections of B. bassiana in wheat as a control measure for Sunn pest and root and crown rot disease.
