1. Evaluation of Antifungal Potential of Leaf Extract of Chenopodium murale Against Fusarium oxysporum f. sp. lycopersici
RESUMO: O presente estudo foi realizado para avaliar a atividade antifúngica e a análise por CG-EM do extrato de folhas de Chenopodium murale contra Fusarium oxysporum f. sp. lycopersici (FOL), um patógeno de tomate altamente problemático no solo. Folhas secas de C. murale foram extraídas com metanol por duas semanas e, após a evaporação do solvente

2. Efficiency of garden waste compost teas on tomato growth and its suppressiveness against soilborne pathogens
ABSTRACT: The use of compost teas is of great interest to sustainable agriculture. Aerated compost tea (ACT) and aerated vermicompost tea (AVT) originating from garden waste have been analytically characterized and tested in vitro and in vivo on tomato plants to determine their suppressive effect on Rhizoctonia solani and Fusarium oxysporum f. sp. lycopersic

3. Impact of water potential on growth and germination of Fusarium solani soilborne pathogen of peanut
Studies were conducted to determine the effect of osmotic and matric stress on germination and growth of two Fusarium solani strains, the etiological agent responsible of peanut brown root rot. Both strains had similar osmotic and matric potential ranges that allowed growth, being the latter one narrower. F. solani showed the ability to grow down to -14 MPa

4. Determinación de las condiciones óptimas para la liberación de zoosporas de Spongospora subterranea en bioensayos
Potato powdery scab is caused by Spongospora subterranea f. sp. subterranea, an obligate parasite and soil-borne pathogen which affects the root system and tubers. It is also a vector of the pomovirus Potato mop-top virus (PMTV). This organism has resistance structures called cystosori which allows it to remain in the soil for years. This study aimed to dete

5. Plant growth-promoting rhizobacteria (PGPR): their potential as antagonists and biocontrol agents
Bacteria that colonize plant roots and promote plant growth are referred to as plant growth-promoting rhizobacteria (PGPR). PGPR are highly diverse and in this review we focus on rhizobacteria as biocontrol agents. Their effects can occur via local antagonism to soil-borne pathogens or by induction of systemic resistance against pathogens throughout the enti

6. Manejo do mofo branco (Sclerotinia sclerotiorum L.) em tomateiro industrial / Management of white mold (Sclerotinia sclerotiorumL.) in tomato industry
Brazil ranks ninth in the world production of tomato (Solanum esculentum L.), while much of this production is destined for processing industries. The added value obtained with the fruit processing endorses this species as the vegetable with the greatest economic importance in the Cerrado region of Brazil, where the State of Goiás stands out as the largest

8. Fusarium oxysporum strains as biocontrol agents against fusarium wilt: effects on soil microbial biomass and activity.
Antes do uso em larga-escala de linhagens nao-patogenicas de Fusarium oxysporum como agentes de biocontrole da murcha-de-Fusarium, o seu comportamento e seus impactos potenciais no solo devem ser estudados como parte da avaliacao de riscos. O objetivo do presente trabalho foi avaliar os efeitos de linhagens antagonistas de F. oxysporum, geneticamente manipul

9. Supressividade de um solo a murcha-de-fusário do caupi e influência da doença no rendimento da cultura
The Fusarium wilt, caused by Fusarium oxysporum f. sp. tracheiphilum, reduces cowpea yield in Northeastern Brazil. This work aimed to characterize the nature and ability to transfer cowpea Fusarium wilt suppressiveness of a soil; to analyze populational dynamic of F. oxysporum f. sp. tracheiphilum and others soilborne microorganisms in two soils with differe

10. Ethylene-insensitive tobacco lacks nonhost resistance against soil-borne fungi
Enhanced ethylene production is an early response of plants to pathogen attack and has been associated with both resistance and susceptibility to disease. Tobacco plants were transformed with the mutant etr1–1 gene from Arabidopsis, conferring dominant ethylene insensitivity. Besides lacking known ethylene responses, these transformants (Tetr) did not slow

11. Plant Colonization by the Vascular Wilt Fungus Fusarium oxysporum Requires FOW1, a Gene Encoding a Mitochondrial Protein
The soil-borne fungus Fusarium oxysporum causes vascular wilts of a wide variety of plant species by directly penetrating roots and colonizing the vascular tissue. The pathogenicity mutant B60 of the melon wilt pathogen F. oxysporum f. sp. melonis was isolated previously by restriction enzyme–mediated DNA integration mutagenesis. Molecular analysis of B60

12. Benzothiadiazole-Mediated Induced Resistance to Fusarium oxysporum f. sp. radicis-lycopersici in Tomato1
Benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH), a synthetic chemical, was applied as a foliar spray to tomato (Lycopersicon esculentum) plants and evaluated for its potential to confer increased resistance against the soil-borne pathogen Fusarium oxysporum f. sp. radicis-lycopersici (FORL). In nontreated tomato plants all root tissue
