The grapevine trunk disease (GTD) has been considered a real threat on grape production. This study aimed to identify the GTD causing agents in Palestinian orchards and evaluate efficacy of bacteria control under vitro conditions. Two fungal isolates; Fusarium solani isolate GR Neofusicoccum parvum GR3 were identified diagnosed using PCR BLASTn analysis. After that, five bacterial isolates test...

In California's Mediterranean climate, management of grapevine trunk diseases (Botryosphaeria dieback, Eutypa Phomopsis Esca) focuses on protecting vines during the dormant season, when pruning coincides with rain-induced spore dispersal causal fungi (‘trunk pathogens’). Applying protectants (fungicides, toxic barriers, sealants, biocontrol agents) after can minimize infection wounds. For seaso...

Petri disease and esca are very destructive grapevine decline diseases that occur in most countries where grapevine (Vitis vinifera) is cultivated. Phaeoacremonium species are among the principal hyphomycetes associated with symptoms of the two diseases, producing a range of enzymes and phytotoxic metabolites. The present study compared the phylogeny of a global collection of 118 Phaeoacremoniu...

Grapevine decline is a top concern in viticulture worldwide and often associated with many biotic abiotic factors. Grape trunk diseases viruses are some of the most frequently identified causes vine dieback. However, sometimes observed when no mineral deficiency or excess, pathogenic can be identified. Soil enzymatic microbial activities relevant bio-indicators since they known to influence hea...

Grapevine decline, a major global viticulture issue, is defined as multi-year decrease in vine productivity and/or increase mortality. Although grapevine trunk diseases are one of the most-studied causes, decline multifactorial and associated with more than 70 factors, including abiotic biotic hazards. With so many factors to consider, phenomenon difficult understand, especially for winegrowers...

grapevine rootstocks are of the potential to increase cultivars, adaptation to different climates, soil types and a variety of unfavorable conditions. considering the existence of a rich grapevine germplasm in iran, it is possible to pick up vigorous genotypes and cultivars as drought tolerant rootstocks for commercial use due to their vast genetic potential. in this study, 698 fruitful genotyp...

Gray mold, caused by Botrytis cinerea, is one of the most destructive diseases of grapevine and is controlled with an intense application of fungicides. As alternatives to chemicals, beneficial microbes may promote plant health by stimulating the plant's immune system. An actinomycete, Streptomyces anulatus S37, has been screened from the rhizosphere microbiome of healthy Vitis vinifera on the ...

Background. Grapevine leafroll disease is one of the most widespread viral diseases in vineyards, affecting nearly all grape and wine regions in the world. Infection causes yield losses, ripening delays, and alters fruit chemistry, including lowering soluble solids and increasing titratable acidity. The viruses associated with leafroll disease are transmitted through propagation of infected mat...
