Abstract The Walnut Twig Beetle (WTB), Pityophthorus juglandis Blackman, is a small bark beetle native to Mexico and Southwestern USA recorded for the first time in Europe (NE Italy) 2013. WTB attacks walnut ( Juglans spp.) wingnut trees Pterocarya vector of Geosmithia morbida Kolarík et al., pathogen causing thousand cankers disease (TCD). TCD represent serious threat orchards Europe. Spatiote...

The incorporation of trees on traditional agricultural land has the potential for providing beneficial conditions understory crops by altering microclimate. Under these assumptions, we conducted a study maize productivity intercropped in 14-year-old walnut orchard measuring growth and yield parameters, water nutrient uptake. Overall, found that decreased maximum air temperature increased humidi...

oxidative stability of walnut (juglansregia l.) was evaluated over a period of 1 year storage in various conditions. the whole walnuts, walnut kernels, walnut chopped kernels, walnut kernels packaged in polyethylene (pet) under vacuum and poly propylene (pp) contain of co2 were kept in a normal condition (temperature, 19-30˚с and relative humidity (rh), 35-45%). the whole walnuts and walnut ker...

this study was conducted to seek the opinion of walnut producers on barriers affecting the success of producers to found production cooperatives regarding horticultural products in tuyserkan township, iran. a sample of 234 walnut producers were randomly selected through multistage cluster sampling technique. descriptive- correlation research method was used in this study which has been implemen...

Here, we report the draft genome sequence of Xanthomonas arboricola pv. juglandis J303, isolated from infected walnut trees in southern Chile. The size of the genome is 5,066,424 bp with a G+C content of 65.4%. X. arboricola pv. juglandis J303 has several genes related to virulence, antibiotic resistance, and copper resistance.

Black meristematic fungi are cosmopolitan and able to adapt to extreme fluctuations of ultraviolet radiation, temperature, and moisture and grow in exposed habitats such as stone surfaces. In a survey on fungi associated with fruit rots, leaf spots, canker, gummosis, dieback and trunk diseases of grapevine and walnut trees in Kurdistan Province (Iran), some black meristematic fungal isolates re...
