Seasonal effect on Brazilian propolis antibacterial activity.
TLDR
There was no significant difference with regards to the seasonal effect on the survival curve of Staphylococcus aureus and Escherichia coli; after incubation with propolis, there was an efficient antimicrobial action, mainly towards Gram-positive bacteria. Expand
First report of Fusarium oxysporum f. sp. lycopersici race 3 on tomato in Brazil
A murcha-de-fusario, causada por Fusarium oxysporum f. sp. lycopersici, e uma das doencas do tomateiro (Lycopersicon esculentum) de maior importância e mais amplamente distribuida no mundo. AteExpand
Phylotype and sequevar variability of Ralstonia solanacearum in Brazil, an ancient centre of diversity of the pathogen
TLDR
This high variability of R. solanacearum in Brazil suggests use of host resistance to control bacterial wilt should be mainly focused by region. Expand
Novel sources of multiple resistance to three races of Fusarium oxysporum f. sp. lycopersici in Lycopersicon germplasm
TLDR
The availability of distinct sources of resistance alleles/genes could be an important tool in breeding to anticipate future problems such as the emergence of other pathogen races besides 1, 2 and 3. Expand
Differential resistance of tomato cultigens to biovars I and III of Pseudomonas solanacearum
TLDR
The reaction of six tomato cultigens to Pseudomonas solanacearum biovars I and III was evaluated in a greenhouse trial and grouped strains of biovar III in a lower virulent cluster than those ofBiovar I. Expand
Leaf spot and stem blight of sweetpotato caused by Alternaria bataticola: a new record to South America.
TLDR
This is apparently the first report of A. bataticola in South America, extending the geographic range of this pathogen to the New World. Expand
A garlic (Allium sativum) leaf blight caused by Stemphylium vesicarium in Brazil
The causal agent of a fohar disease of garlic (Allium sutivum) was identified as Stemphylium resicarium (Wallr) Simm Disease symptoms were reproduced on garlic leases 8 to 10 days after inoculationExpand
Molecular characterization of Ralstonia solanacearum infecting Eucalyptus spp. in Brazil
TLDR
The results of the analysis of fragments amplified using the ERIC-PCR technique indicated the existence of genetic diversity among the strains studied, with a generally high correlation between similarity and the geographical origin of the strains. Expand
Powdery mildew of Allium species caused by Oidiopsis taurica in Brazil
TLDR
The first formal report of a powdery mildew disease on species of the genus Allium in Brazil is reported, which might become important on these vegetable crops especially in hot and dry areas such as those in the Central and Northeast regions of Brazil. Expand
