1. Intercropping of wheat changed cucumber rhizosphere bacterial community composition and inhibited cucumber Fusarium wilt disease
ABSTRACT: Enhancing the plant rhizosphere microbial community function by increasing plant diversity in the field is a promising strategy for enhancing agricultural sustainability. This study evaluated the effectiveness of the intercropping of wheat in controlling cucumber Fusarium wilt disease. Bacterial community diversity and abundance in cucumber rhizosp

2. Diversity of Endophytic and Epiphytic Bacteria From Sugarcane in Khuzestan, Iran
Abstract Diverse microorganisms are living as endophytes in plant tissues and as epiphytes on plant surfaces in nature. Commercial formulations of bacteria antagonist to plant pathogenic microbes and ice nucleation active bacteria have been utilized as an environmentally safe method to manage plant disease and to prevent frost damage respectively. Bacteria w

3. Combination of solarization, biofumigation and grafting techniques for the management of bacterial wilt in tomato
RESUMO Objetivou-se avaliar o efeito da combinação das técnicas de solarização, biofumigação com cama de frango e enxertia na incidência da murcha bacteriana e na produtividade do tomateiro híbrido Absoluto. Foram realizados dois experimentos, em casa de vegetação tipo capela e em campo, no ano agrícola 2013/2014, em propriedade agrícola no muni

4. Morphological identification of Ilyonectria liriodendri and its interaction with plant growth-promoting bacteria in grapevine rootstocks
Resumo Com a finalidade de analisar a patogenicidade e o antagonismo entre porta-enxertos de videiras e microrganismos de solo, procedeu-se à seleção de bactérias promotoras de crescimento de plantas com efeito antibiótico ao fitopatógeno Ilyonectria liriodendri, isolado monospórico 2T-VSC-101, em testes de antibiose in vitro. O acesso bacteriano que

5. Green propolis ethanolic extract in bean plant protection against bacterial diseases
RESUMO: Este trabalho teve como objetivo avaliar o extrato etanólico de própolis verde (EEP) na proteção de plantas de feijoeiro contra as duas principais bacterioses da cultura, crestamento bacteriano (Xanthomonas axonopodis pv. phaseoli) e fogo selvagem (Pseudomonas syringae pv. tabaci). Foram realizados experimentos sobre atividade antimicrobiana ind

6. Bacterial selection for biological control of plant disease: criterion determination and validation
Abstract This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial compounds (ammonia and antibiosis) and hydrolytic enzymes

7. The diversity of citrus endophytic bacteria and their interactions with Xylella fastidiosa and host plants
Abstract The bacterium Xylella fastidiosa is the causal agent of citrus variegated chlorosis (CVC) and has been associated with important losses in commercial orchards of all sweet orange [Citrus sinensis (L.)] cultivars. The development of this disease depends on the environmental conditions, including the endophytic microbial community associated with the

8. Plant growth-promoting bacteria as inoculants in agricultural soils
Abstract Plant-microbe interactions in the rhizosphere are the determinants of plant health, productivity and soil fertility. Plant growth-promoting bacteria (PGPB) are bacteria that can enhance plant growth and protect plants from disease and abiotic stresses through a wide variety of mechanisms; those that establish close associations with plants, such as

9. Isolation of
Dickeya dadantii strains from potato disease and biocontrol by their bacteriophagesOne of the most economically important bacterial pathogens of plants and plant products is
Dickeya dadantii . This bacterium causes soft rot disease in tubers and other parts of the potato and other plants of theSolanaceae family. The application of restricted host range bacteriophages as biocontrol agents has recently gaBraz. J. Microbiol.. Publicado em: 21/07/2015

10. Biological control of tomato bacterial spot by seed microbiolization
Six plant growth promoting rhizobacteria isolates - two Streptomyces (DFs1296 and DFs1315), three Bacillus (DFs1414, DFs1420 and DFs1423) and one Pseudomonas (DFs1421) - were used to microbiolize tomato seeds for the control of bacterial spot caused by Xanthomonas gardneri. Three assays were conducted in a completely randomized design with six replications.

11. Cultivable bacteria isolated from apple trees cultivated under different crop systems: Diversity and antagonistic activity against Colletotrichum gloeosporioides
This study evaluated the diversity of cultivable plant growth-promoting (PGP) bacteria associated with apple trees cultivated under different crop management systems and their antagonistic ability against Colletotrichum gloeosporioides. Samples of roots and rhizospheric soil from apple trees cultivated in organic and conventional orchards in southern Brazil

12. Potential of ethyl acetate fractions of Stryphnodendron adstringens shells and fruit extracts of Caesalpinia ferrea to control bacterial leaf speck and on the potentiation of defense enzymes in tomato
Considering the importance of bacterial leaf speck (Pseudomonas syringae pv. tomato) in reducing tomato yield and difficulties in disease control, this study investigated the effects of fractions of shells extract of Stryphnodendron adstringens (Sa) and fruit extract of Caesalpinia ferrea (Cf) compared to Acibenzolar-S-Methyl (ASM) on reducing bacterial leaf
