Goal. The study of the effectiveness technology of potato cultivation for the phytosanitary state of tubers in the conditions of the Polesie region of Ukraine. Methods. Research of production crops of the Gabenets farm. Monitoring of major fungal diseases on potato tubers. Identification of phytopathogens on potato tubers. Farming technology consisted of 9 stages and included 6 herbicide-fungicidal treatments in the growing season of potato plants. Samples were collected and phytopathological analysis of potato tubers during harvest was conducted according to conventional methods. Identification of pathogens of fungal diseases was carried out at the Institute of Plant Protection of the National Academy of Sciences of Ukraine, according to conventional methods. Results. The performance of potato varieties in the application of a set of protection measures in FG “Gabenets” was evaluated. It was analyzed that the yields of varieties on the production crops of the farm were quite high and ranged from 50.25 to 58.10 t / ha, and the yield from one bush — from 1.014 kg to 1.163 kg. The highest yield was on production crops of the Pirol variety and amounted to 58.10 t / ha, compared to the control — 47.30 t / ha. Phytopathological analysis of potato chips varieties was carried out, which resulted in the detection of dry fusarium potato rot in control variants of Opal, Karlenа, Fantasia and Kibitz. No crop disease was detected in production crops where a system of protective measures was applied. Pirol cultivar has proven to be resistant to fungal pathogens. Conclusions. Protective measures during the vegetation of potato plants prevented the mass development of fungal diseases on potato tubers, which in turn will have a positive effect on the stickiness of the tubers and preserve their marketability.

Potato Pathogens

Fungi are considered as serious pathogens to many plants and can cause a severe economic damage. The available methods for identification of fungi are time consuming and not always very specific. In the present study we examined the potential of FTIR microscopy for direct detection and identification of different fungal potato pathogens on the surface of potato tubers. Unique spectral bands for each of the examined fungal pathogens appeared in the spectra of naturally infected potatoes. These results strongly support the potential of FTIR microscopy for successful detection and probably discrimination between different fungal pathogens directly from the infected tissue.

Set Up

Fusarium solani, a soil-borne pathogen of stored potato may be disseminated, and thus, the damage caused by the pathogen may be aggravated by the grazing activities of arthropods. To investigate whether terrestrial woodlice contribute to the spread or, instead, to the control of F. solani, we launched a series of pilot experiments. First, a laboratory feeding trial was set up to find whether and to what extent woodlice consume the mycelia of fungal pathogens, namely, Aspergillus niger, F. solani, Macrophomina phaseolina, and Sclerotinia sclerotiorum. This was followed by a second set of experiments to simulate storage conditions where potato tubers, either healthy or infected with F. solani, were offered to woodlice. We found that: (1) F. solani was accepted by woodlice but was not their most preferred food source; (2) the presence of woodlice reduced the spread of F. solani among potato tubers. Our results suggest that the classification of terrestrial woodlice as “storage pests” needs re-evaluation, as isopods have the potential to disinoculate infective plant remnants and, thus, reduce the spread of storage pathogens.

Sooty mould diseases of Tress from Aurangabad district were surveyed. During the survey of tress, 5 species were found infected by fungal pathogens causing sooty mould diseases. Disease is easily identifiable by the presence of a black, velvety growth covering the leaf surface area. The fungus produces mycelium which is superficial and dark grows on the flowers, leaf, stem and sometime on fruits also. The severity of disease depends on the honeydew secretions by insects. The diseases were found to be caused by 5 species of fungi viz. Capnodium anonae, C. ramosum, Capnodium sp., Meliola bangalorensis and Meliola ranganthii.
