Biocontrol and Biostimulant Effect of a Fungal-Derived Extract in Commercial Varieties of Strawberry (Fragaria x ananassa Duch.)

“…Interestingly, the effect of CF on strawberry fruits does not depend on the particular genotype. Likewise, the results are consistent with previous studies in which we demonstrated CF could induce local and systemic protection against B. cinerea in Arabidopsis thaliana [38] and Fragaria x ananassa cultivar "Pájaro" [45] .…”

“…Unlike the commercial fungicide Switch®, which inhibits conidia germination and thus shows an antifungal mode of action, CF does not affect the elongation of conidia germ tubes, the mycelium growth, or the hyphae morphology or membrane cells permeability when tested in vitro [38] . However, CF exerted some kind of damage on B. cinerea that was unable to infect detached strawberry leaves, despite it could normally grow in vitro [45] . Thus, this phenomenon could be happening in postharvest strawberry fruits pre-treated with CF, which may inhibit the virulence of quiescent B. cinerea fungi slowing down the appearance of grey mould symptoms and diminishing the incidence of the fungus.…”

Phytovaccines, a New Paradigm for Crop Protection: Towards a Sustainable Agriculture

“…Two elicitors were obtained from strawberry leaves, the Fragarin [24] and the Ellagitanin HeT [25] and the elicitor Acremonium strictum Elicitor Subtilisin (AsES) that was purified from the avirulent fungus Acremonium strictum [26][27][28][29][30][31][32] . We have also investigated the two synthetic brassinosteroids (e.g., EP24 and BB16) with both plant defense and plant growth stimulation capacities [33][34][35] , and fungal-derived extracts, which are a complex mixture of elicitors-the latter may be comparable those vaccines made with whole inactivated pathogens [36,37] . Just to mention, we have also induced innate defenses in strawberry plants through a soft mechanical stimulus [38] , similar to what was previously observed by Benikhlef et al [39] in the model plant Arabidopsis thaliana.…”

Biocontrol of Litchi Downy Blight Dependent on Streptomyces abikoensis TJGA-19 Fermentation Filtrate Antagonism Competition with Peronophythora litchii

“…There is a pressing necessity to investigate alternative approaches for controlling litchi downy blight, while minimizing adverse impacts on both human health and the environment. In this context, biocontrol agents represent environmentally safer alternatives for protecting plants or fruit against disease [4]. The inherent characteristics of specific microorganisms and their metabolic processes can be manipulated for the purpose of plant disease management [5].…”
