The vine mealybug (VM), Planococcus ficus (Signoret), is an Afrotropical species, whose worldwide populations probably originated from the Mediterranean basin. It was introduced to the Americas during the second half of the 20th century (Ben-Dov 1994; Gill 1994). Until the early 1980s, this pest was frequently misidentified as the citrus mealybug, Planococcus citri (Risso), as both Planoccocus ...

‘Malbec’ grapevines commonly have high yield, thus intermittently negatively affecting wine quality parameters. Here, we describe the use of late shoot pruning (LSP) practice applied for improvement. We examined effect timing LSP on vines grown in Mediterranean conditions during three consecutive seasons (2016–2018) Israel. The treatment applications (applied one, two and weeks after bud break)...

The modified sigmoidal bacteria growth functions (the Gompertz, logistic, and Richards) were used to evaluate the methane production process kinetics of agricultural wastes. mesophilic anaerobic co-digestion experiments conducted with various wastes as feedstocks, including cow manure, corn straw, grape leaves, vines, wine residue, strawberry tomato leaves. results showed that manure other incr...

frost in early spring is one of the limiting factors in the production of grape. chemicals offer useful approach to reduce low temperature-induced damages. different concentrations of salicylic acid including: 0 (control), 0.5, 1 and 2 mm were sprayed twice on 10 year-old ‘bidaneh sefid’ grape vines at full bloom stage and changes in leaf soluble carbohydrates, proline and protein levels were m...

In order to counteract the various effects of climate change on physiology grapevine and quality grapes leading wine produced, many different approaches have been proposed. The aim this study was assess effect cultivation techniques quantitative qualitative characters cv Xinomavro, during season 2019-2020. experimental vineyard is located in Giannakochori, Naoussa (Greece), where vines are trai...

Vitis vinifera grapevines are highly susceptible to downy mildew caused by the host-specific oomycete Plasmopara viticola. In humid climates like New York, where the unchecked pathogen will defoliate vines and destroy young fruit clusters, growers depend upon multiple fungicide applications for disease management. However, management of P. viticola by fungicides is tenuous, because the pathogen...

Winemaking is a well-known process comprising several steps to produce must and wine. Grape marc byproduct of wine production that can be vermicomposted used as organic fertiliser. vermicompost has richer more stable microbiome than grape alone when added the soil vineyards it improve quality. We compared Albariño microbiotas from grapevines treated with derived controls (standard fertilisation...

T h e nor thern root-knot nematode, Meloidogyne hapla Chitwood, 1949, parasitizes a number of impor tant crops in Washington (1). M. hapla is widespread on Concord grapes (Vitis labrusca L.), and heavy infestations have been associated with vines with poor growth. All the same, a greenhouse pathogenicity study with an isolate of M. hapla from alfalfa (Medicago sativum L.) showed that Concord gr...

abstract large-scale mortality of in vitro raisedplantlets occurred during acclimatization, i.e. glasshouse hardening, and later at field transfer still has remained as a significant bottleneck in micropropagation. the usefulness potential of some arbuscular mycorrhizal fungi (amf) to minimize mortality rate of three commercial grape rootstock genotypes during glasshouse acclimatization was stu...
