The article presents the results of the development of an electronic directory (information system) on the phytosanitary requirements of countries importing Russian grain products. The methods, main stages and features are described. The practical significance and prospect of further data input and the development of the information system are assessed.

The article presents traditional, as well as modern techniques of identification of fruit crop moniliosis – fungi of the genus Monilinia – used in phytosanitary diagnosis, such as conventional PCR, qPCR, and multiplex PCR. The new MALDI-ToF MS mass spectrometry technique is described, as well as techniques of latent pathogen infection detection.

The genus Begomovirus includes more than 190 species of viruses, which are harmful pathogens of vegetable and field crops. Tomato yellow leaf curl virus (TYLCV), which is widely spread in Europe, is a quarantine object for the Russian Federation, EAEU and EPPO. Identifying begomoviruses to the species level involves certain difficulties due to the high identity of their genome. The article presents the results of testing 19 pairs of universal and specific primers for the diagnosis of begomoviruses: tomato leaf curl virus (TYLCV), tomato yellow leaf curl Sardinia virus (TYLCSV), and tomato leaf curl New Delhi virus (ToLCNDV) by conventional and real-time PCR methods.

During a research expedition to the Socialist Republic of Vietnam, undertaken to collect quarantine and other insect pests and weeds, material including 14 species of thrips was collected. Data on the distribution, biology of collected thrips species and their brief morphological characteristics are presented. Five species of thrips, which are of phytosanitary importance for Russia, as well as six species that have not been previously registered in the fauna of Vietnam, were identified.
