1. Effect of adding fungicide to mixtures of triazoles and strobilurins in the control of downy mildew and Asian soybean rust
RESUMO Os fungicidas utilizados para o controle da ferrugem asiática da soja são constituídos por misturas entre os modos de ação sistêmicos (triazóis) e meso-sistêmicos (estrobilurinas). Entretanto, para o controle do míldio da soja, existem disponíveis apenas fungicidas protetores. Objetivou-se avaliar a eficácia de fungicidas com diferentes mod

2. Behavior of grape breeding lines with distinct resistance alleles to downy mildew (Plasmopara viticola)
Abstract Downy mildew (Plasmopara viticola) is the main grapevine disease in humid regions. In the present investigation, marker-assisted selection (MAS) was used to develop grapevine lines homozygous in loci Rpv1 and Rpv3 for resistance against P. viticola. The experimental populations UFSC-2013-1 (n = 420) and UFSC-2013-2 (n = 237) were obtained by self-po

3. 'BRS Vitória' - a novel seedless table grape cultivar exhibiting special flavor and tolerance to downy mildew (Plamopara viticola)
'BRS Vitória' is a novel cultivar of black seedless table grape. Its main traits meet the most important demands from the viticulture segment in Brazil.It is recommended for cultivation in tropical and subtropical areas, with excellent horticultural performance, high bud fecundity and resistance to downy mildew, the most important disease which affects grap

4. Cultivo fora de época da videira BRS Clara sob cobertura plástica
The system of production of grapes under plastic cover is an alternative to reduce pesticide treatments in table grapes in Northern Paraná, once that the hot and humid climate favors the occurrence of fungal diseases, especially during the out of season crop. The aim of this study was to evaluate the ripening evolution, the physico-chemical characteristics

6. Controle alternativo do míldio e da antracnose da videira com extrato aquoso de cinamomo (Melia azedarach L.) / Alternative control of downy mildew and anthracnose of grape aqueous extract of chinaberry (Melia azedarach L.)
The objective of this study was to evaluate different concentrations of aqueous extract of chinaberry (Melia azedarach L.) on the control of downy mildew (Plasmopara viticola) and anthracnose (Elsinoe ampelina) of grapevines cvs. Isabel and Cabernet Sauvignon. For all experiments the aqueous extract of chinaberry was prepared by addition of fruit with seeds

7. Controle químico do míldio (Peronosclerospora sorghi) em sorgo.
Sementes de sorgo da cultivar SC 283, altamente suscetível a Peronosclerospora sorghi, foram utilizadas nos três experimentos deste trabalho. Para avaliação do controle de conídios de P. sorghi veiculados pelas sementes, estas foram previamente tratadas com os seguintes fungicidas (g i.a.100 kg-1 sementes): metalaxyl-M + mancozeb (5,6 + 89,6), metalaxyl

8. UFUS Guarani: new soybean cultivar for the state Minas Gerais
Day by day alternatives in genetic improvement are being been sought to ensure higher crop productivity. UFUS Guarani developed by the Federal University of Uberlandia is resistant to natural dehiscence and to the diseases: Sudden death syndrome (SDS), frogeye leaf spot, downy mildew, bacterial pustule, stem canker and stem necrosis; the potential yield is 3

9. Mutations in retrotransposon AtCOPIA4 compromises resistance to Hyaloperonospora parasitica in Arabidopsis thaliana
Retrotransposons (RTEs) are a principal component of most eukaryotic genomes, representing 50%-80% of some grass genomes. RTE sequences have been shown to be preferentially present in disease resistance gene clusters in plants. Arabidopsis thaliana has over 1,600 annotated RTE sequences and 56 of these appear to be expressed because of the exact expressed se

11. Impact of downy mildew on soybean yield in South of Mato Grosso do Sul, 2006/2007 crop season / IMPACTO DO MÍLDIO NA PRODUTIVIDADE DA SOJA NO SUL DE MATO GROSSO DO SUL, SAFRA 2006/2007
Foliar diseases that attacks soybean crop constitutes one of the main limiting crop yields for soybeans. Soybean downy mildew, caused by the oomycota Peronospora manshurica, is one of the diseases of major distribution in all regions of the world where soybean is cultivated. Soybean downy mildew can damage leaves and in some cases pods. This research aimed t

12. Caracterização genética da resistência ao míldio (Peronosclerospora sorghi) em sorgo (Sorghum bicolor L. Moench) / Genetic characterization of the resistance to the downy mildew (Peronosclerospora sorghi) in sorghum (Sorghum bicolor L. Moench)
No presente trabalho, foram avaliadas 13 linhagens de sorgo do programa de melhoramento genético da Embrapa Milho e Sorgo quanto à reação a nove raças de Peronosclerospora sorghi. Dentre as linhagens foram identificadas cinco fontes de resistência às nove raças (BTx623, Tx430, SC414-12, QL- 3 e ARG-1) e duas linhagens (SC283 e ATF14B) susceptíveis �
