Passion fruit (Passiflora edulis) and cowpea (Vigna unguiculata) are two agricultural crops of considerable economic importance in Northeastern Brazil. Fruit woodiness caused by isolates Cowpea aphid-borne mosaic virus biotype P (CABMV-P) is the most important disease that occurs on passion Brazil (CABMV-C) responsible for common The objective present research was to determine biological relationships between CABMV-C obtained from (CABMV-CFor CABMV-CBv) CABMV-P (CABMV-PMild CABMV-PSevere)...
Neste trabalho utilizou-se o método Taguchi (planejamento Robusto de experimentos), para cumprir com um reduzido número ensaios, dois objetivos: obter a influência dos fatores controle sobre as variáveis respostas e determinar condições ideais aplicação das ligas níquel nas soldagens revestimentos através do processo MIG/MAG transferência metálica por curto-circuito. Foram escolhidos seis três níveis cada: Tensão referência, Velocidade soldagem, Tipo tecimento, Técnica da tocha, Gás proteção...
ABSTRACT Treatments with pyraclostrobin, a fungicide from the strobilurin chemical group, have induced physiological effects in several plants, which may influence their productivity. In this study, two experiments were carried out to study effect of commercial product containing pyraclostrobin + metiram on productivity and virus dissemination potato cultivars. The first experiment was Maria da Fé-MG, applying different combinations via furrow at planting foliar application, post-emergence,...
The objective the work was to investigate effect of insecticide treatments on virus spread and in potato yield, as well evaluate residue value insecticides employed tubers subjected these treatments. experiment carried out with two cultivars randomized blocks 40 tubers, 4 replications 12 treatments, follows: 1) spraying (SI) leaves once a week, last application at 55 days after planting (DAP); 2) SI 69 DAP; 3) DAP + Cabrio Top; 4) every five days, 5) 80 6) control, no plant emergence; all...
Neste trabalho foram calculados e comparados os custos de soldagem associados a cada um dos ensaios realizados, como forma determinar parâmetros operacionais adequados economicamente viáveis para com o processo MIG/MAG transferência metálica por curto-circuito, visando uma correta deposição revestimentos ligas níquel sobre substrato aço C-Mn. O número serem foi determinado pelo uso do método Taguchi que dividiu em duas matrizes L9, resultando num total 18 ensaios. Na comparação gastos...
Vinte e nove genotipos de meloeiro 38 melancia foram avaliados contra inoculacoes artificiais com Papaya ringspot virus (PRSV), Watermelon mosaic (WMV) Zucchini yellow (ZYMV), especies virais do genero Potyvirus , familia Potyviridae . Dezesseis plantas cada genotipo inoculadas um dos quatro mantidas sem inoculacao para especie viral, como testemunha, em casa vegetacao. As observadas relacao aos sintomas testadas por enzyme linked immunosorbent assay (ELISA) indireto anti-soros especificos...
