Root rot grain crops on Cereals caused by the phytopathogenic fungi

Abstract

Researching the special and infraspecial structure in causative agent populations of the most dangerous diseases root rots of cereals in various regions of the Russjan Federation has been carried out. The defeat of cereals root rots old in Russia causes in the a complex patogenic. More often meet Fusarium culmorum (W.G.Sm.) Sacc., F. oxysporum (Schlecht.) Snyd.et Hans., F. heterosporum Nees., F. sporotrichiella nom.nov. Bilai F. gibbosum App.et Wr.emend Bilai., F. avenaceum (Fr.) Sacc. and Bipolaris sorokiniana (Sacc.) Shoem., Alternaria spp.

Highly sensitive photodetectors on the basis of Au-oxide-n-GaP0.4As0.6

“…In structures, in which δ≈47 Å, the dielectric layer is thick enough to noticeably hinder the transition of hot photoelectrons from the semiconductor to the metal, while at the same time it is thin enough not to strongly impede the transition of photoholes from the semiconductor to the metal. Here, the relative short-wavelength PS [If0(4.0 eV) / If0(hυm)] is 1.5-2 times higher than in structures with very thin (δ≈10 Å) and relatively thick (δ≈83 Å) dielectric layers [13][14][15].…”

Screening and identification of abiotic stress-responsive efficient antifungal Pseudomonas spp. from rice rhizospheric soil

“…are also well known as post harvest pathogens. A. triticina is one of the several species in the genus that have been isolated from wheat leaves; it is demonstrated to be pathogenic, whereas other species appear to be primarily saprophytes (Grebenikova et al, 2018 ). The leaf blight disease caused by A. triticina is a serious problem for susceptible cultivars of durum ( Triticum turgidum subsp.…”
