Grapevine leafroll-associated virus 3
Grapevine leafroll disease (GLD) is one of the most important grapevine viral diseases affecting grapevines worldwide. The impact on vine health, crop yield, and quality is difficult to assess due to a high number of variables, but significant economic losses are consistently reported over the lifespan of a vineyard if intervention strategies are not implemented. Several viruses from the family...
متن کاملSerological Detection of Grapevine Associated Closteroviruses in Infected Grapevine Cultivars
Grapevine leafroll (LR) and corky bark (CB) diseases occur wherever grapevines are grown and are associated with undesirable viticultural effects which include delayed ripening of fruit, reduced yield, altered fruit pigmentation, and reduced accumulation of sugar (6,24). Rootstockscion incompatibility (RSI) is a disease syndrome characterized by incompatibility at the graft union resulting in s...
متن کاملEffect of host plant tissue on the vector transmission of grapevine leafroll-associated virus 3.
Many biotic and abiotic factors affect the transmission efficiency of vector-borne plant pathogens. Insect vector within-plant distribution and host tissue preference are known to affect pathogen acquisition and inoculation rates. In this study, we first investigated whether feeding tissue affects the transmission of Grapevine leafroll-associated virus 3 by Planococcus ficus (Signoret) (Hemipte...
متن کاملOccurrence of Grapevine Leafroll-Associated Virus Complex in Napa Valley
Grapevine leafroll disease (GLD) is caused by a complex of several virus species (grapevine leafroll-associated viruses, GLRaV) in the family Closteroviridae. Because of its increasing importance, it is critical to determine which species of GLRaV is predominant in each region where this disease is occurring. A structured sampling design, utilizing a combination of RT-PCR based testing and sequ...
متن کاملEcology and management of grapevine leafroll disease
Grapevine leafroll disease (GLD) is caused by a complex of vector-borne virus species in the family Closteroviridae. GLD is present in all grape-growing regions of the world, primarily affecting wine grape varieties. The disease has emerged in the last two decades as one of the major factors affecting grape fruit quality, leading to research efforts aimed at reducing its economic impact. Most r...
