Distribution and species composition of potato viruses in the Novosibirsk region.

Among the many diseases that affect potato plants, viral infections are the most common and cause significant damage to farms, affecting both the yield and quality of potatoes. In this regard, an important condition for preserving the potato seed fund in Russia is systematic monitoring and early highly specific detection of potato viral infections. The purpose of the work is to study samples of potato varieties collected in the Novosibirsk region for the presence of viral infections using RT-PCR.

and Mix Suppresses Rhizoctonia Disease and Improves Rhizosphere Microbiome, Growth and Yield of Potato ( L.).

Black scurf and stem canker caused by is a significant disease problem of potatoes. Currently, chemical methods are the primary means of controlling this pathogen. This study sought to explore an alternative approach by harnessing the biocontrol potential of a bacterial mix of and against black scurf, and to determine their effect on rhizosphere microorganisms of soil microbiota.

Luminescent Coatings Based on (3-Aminopropyl)triethoxysilane and Europium Complex β-Diketophosphazene.

The reaction of β-diketophosphazene with the europium (III) salt synthesized the corresponding metal complex which was structured with (3-aminopropyl)triethoxysilane and treated with dibenzoylmethane for additional coordination of europium atoms. The polymer thus obtained exhibits luminescence with a maximum of 615 nm, which is characteristic of europium. The polymer is thermally stable up to 300 °C, the coating based on it has a contact angle of 101°, and the adhesive strength of the coating to non-finished glass (according to ISO 2409: 2013) is 1 point.

Biological control of important fungal diseases of potato and raspberry by two strains.

Stem canker and black scurf caused by are the important diseases in potato, while spur blight caused by is a major disease in red raspberry. In Western Siberia, both crops are grown predominantly in small-scale farming that requires maximal usage of biological products for plant protection instead of chemicals. We evaluated two promising strains BZR 336 g and BZR 517 isolated in the south of Russia (45°1'N, 38°59'E) for their biological control potentials against the potato and red raspberry diseases under the more severe weather conditions of Western Siberia (55°1'N, 82°55' E).

Design and study of phosphocavitands-a new family of cavity systems.

The design of phosphorus-containing cavity architectures that are of interest for biomimetics and other interdisciplinary sciences is among the most high-priority lines of research in modern organophosphorus chemistry. This Account acquaints the readers with methods for the design of rigid phosphomacrocyclic systems based on resorcinarenes, which differ in the nature of the phosphorus functions on the upper rim of the molecular bowl and have fixed dimensions of the molecular cavity. The authors demonstrate the possibility of attaining stereoselectivity in the synthesis of phospho(III)cavitands and their various transformations.
