Resumen

Aim. Phytopathogenic microorganisms are one of the main causes of agricultural productivity losses. Thereby, the goal of this study was to evaluate actinomycetes strains, isolated from Juniperus excelsa Bield. rhizosphere, antagonistic activity against plant pathogenic bacteria and fungi. Methods. In this study we used microbiological methods for isolation actinomycetes from rhizosphere. Antagonistic activity was evaluated by using the dual culture method. Results. 372 actinomycete stains were isolated from J. excelsa Bield. rhizosphere. More than 60 % actinomyces isolates showed antibacterial

Resumen

Antibiotic production by plant-associated microorganisms represents an environmentally compatible method of disease control in agriculture. However, a vide application of bacterial strains needs careful selection and genetic characterization. In this investigation, selected Pseudomonas strains were characterized by rep-PCR methods using ERIC and (GTG)5 primers, and partial 16S rDNA sequence analysis. None of strains produced homoserine lactones (C4, C6, C8) as quorum sensing signal molecules. Very poor production of phenazines and no significant fungal inhibition was observed for PS4 and PS6 s

Resumen

Abstract Antagonistic activity of microorganisms against phytopathogens is mainly the results of plants’ health improvement due to the inhibition of pathogens growth and the induction of plants resistance against diseases. The aim of the research was to determine antagonistic properties of Pantoea agglomerans against Rhizoctonia solani. The properties of two strains P. agglomerans BC17 and BC45 were assessed according to the following criteria: mycelial growth of R. solani in the presence of bacterial metabolites, an impact of P. agglomerans on the growth of sugar beet in the pots containing s

Resumen

Many candidate mycoherbicides have shown promise in the laboratory or greenhouse, but most have been ineffective in the field. Factors limiting mycoherbicide efficiency include temperature and humidity. Results from this thesis indicate that solar radiation has both a damaging effect(reduction in germination)limiting efficacy and a photomorphogenic effect(appressorium induction)increasing efficacy. The study has also shown significant interaction between temperature and solar radiation on the survival of conidia of potential mycoherbistats. Therefore, solar radiation should be considered as th

Resumen

The plant pathogen Ralstonia solanacearum is the causal agent of the devastating disease known as bacterial wilt. This disease affects more than 200 plant species in over 50 families, including economically important crops such as tomato, potato, banana or pepper. R. solanacearum is a soil-borne and vascular pathogen. It enters its hosts through wounds in the roots and lateral root emerging sites. Then, the pathogen traverses the cortical apoplast until it reaches the vascular cylinder and colonizes to very high numbers the xylem vessels. The combination of bacterial growth and the secretion o
