abstract disease incidence and favorable condition on disease severity is evaluated. w. carpophilus isolated of infected orchards. for fungus overwintering method in buildup were carried out bud washing by centrifuge and spot culturing on nutrient mediums. evaluation of shot hole in different areas showed that cultivars response to this disease is fixed inside of a climate but it is differ in d...

shot hole caused by wilsonomyces carpophilus is one of the main constraints to prune fruit production in iran particularly in khorasan razavi province. it causes foliage shot hole in spring and early summer; fruit-spotting and cankers on limbs and twigs during autumn rains. the fungus was isolated from the lesions of twigs and was purified on pda. the pathogenicity and virulence on detached twi...

Shot hole disease of stone fruit trees, caused by Wilsonomyces carpophilus (Lév.) Adaskaveg, Ogawa & Butler(= Stigmina carpophila (Lév.) M.B. Ellis and Coryneum beijerinckii Oud.) is a serious disease of Prunus species in West Azerbaijan province. The pathogen was obtained from infected leaves, fruits and twigs of Prunus orchards during spring and summer of 2007. Samples were cultured on PDA, M...

In the present research, the mixed-mode fracture mechanics analysis in a plate with central hole under tensile loading is considered. It is assumed that a plate containing two symmetrical hole-edge cracks is bonded with two dissimilar planes. The stress intensity factors at the crack tips are calculated. The problem is modeled in Casca software and this model is analyzed with Franc software. Th...

The polyphagous shot hole borer and Kuroshio shot hole borer, two members of the Euwallacea fornicatus species complex (Coleoptera: Curculionidae: Scolytinae), are invasive ambrosia beetles that harbor distinct species of Fusarium fungal symbionts. Together with the damage caused by gallery construction, these two phytopathogenic Fusarium species are responsible for the emerging tree disease Fu...

X-ray variability of the microquasar XTE J1550-564 is studied with time domain techniques for the data from the RXTE/PCA observation in September 8, 1998. The 2–60 keV averaged shot is obtained from superposing shots with one millisecond time bin through aligning their peaks. The spectral behavior during the averaged shot exhibits prominent differences from that observed in Cyg X1. The hardness...

in this study, eleven cultivars of apricot including two early ripening (noori pishras and pishras tabasi) varieties, four mid ripening cultivars namely (shahroudi, lasjrdy, ghazi gahani and bagheri) and five late ripening cultivars i.e. (shahroudi51, shahroudi48, shahroudi29, shahroudi21 and ketabi) that had a better yield and horticultural characteristics were screened to wilsonomyces carpoph...

Shot hole, caused by Stigmina carpophila (Lev.) M.B. Ellis, is a major fungal disease for apricots and it causes serious economic loss in Turkey. To protect from the various destructive effects of shot hole disease, excessive fungicide used, which may lead to severe damage ecosystem. One most beneficial alternative ways minimize or eradicate hazardous fungicides use resistant/moderately resista...
