This leads to a problematic emergence of resistance to chemical pesticides in the phytopathogens. The main cause of this is that less than 0.1% of the pesticides used for pest control reach their targets accurately, leaving the rest of the active substances in the ecosystems. Negative impacts on biotic components can occur at different levels from individual organisms to communities, affecting the balance of the whole ecosystem. But since 1963, the negative impacts of pesticides on human health, wildlife and environment have been extensively reported. All these benefits allowed the worldwide population to expand. By improving the quality and the yield of plant productions, and controlling agricultural pests, chemical fertilizers and pesticides brought beneficial effects to society. The use of chemical compounds designed by humans to improve health and productivity of plants has strongly expanded. Since the Green revolution, the way crops are grown has seen profound change.

PLoS ONE 14(12):Д®ditor: Petr Karlovsky, Georg-August-Universitat Gottingen, GERMANY (2019) Does in vitro selection of biocontrol agents guarantee success in planta? A study case of wheat protection against Fusarium seedling blight by soil bacteria. graminearum must be preferentially based on the direct screening of strains for their protective activity on wheat plants against fungal diseases, rather than on their in vitro antagonistic effects on fungal growth.Д¬itation: Besset-Manzoni Y, Joly P, Brutel A, Gerin F, SoudiГЁre O, Langin T, et al. Thus, developing a biocontrol product against F. Interestingly, some strains belong to species ( Microbacterium, Arthrobacter, Variovorax) that are not known in the literature for their ability to protect plants against fungal pathogens. We find strains which do not have inhibition phenotypes in vitro but good efficacy in planta.

graminearum, and in an in planta experiment. A library of 205 soil bacteria was screened in 2 types of in vitro growth inhibition tests against F. But is the in vitro selection of bacterial agents according to their antagonism activities towards a plant pathogen the best way to get effective biocontrol products? To answer this question, we used wheat and the fungal pathogen Fusarium graminearum as a study pathosystem model. Strains with no in vitro effect are often discarded and not tested in planta. When new biocontrol products are developed, strains were mostly selected based on their ability to inhibit a pathogen of interest under in vitro conditions via antagonistic effects. It often involves microorganisms or molecules produced by microorganisms that will be able to interact with either a plant or pathogens of this plant to reduce the growth of the pathogen and limit its negative impact on the host plant. Biological control is a great hope for reducing the overutilization of pesticides in agricultural soils.
