Influence of metabolism products of entomopathogenic nematodes symbiotic bacteria on the harvest of potato
Practical interest is represented by researches of efficiency of new biological preparations as protection frames of a potato Solanum tuberosum Z. The paper gives the results of experiments on application of metabolism products of entomopathogenic nematodes symbiotic bacteria (Xenorhabdus, Enterobacteriaceae) in cultivation of potato, their influence on the harvest, its biochemical composition. Efficiency of application of metabolism products of entomopathogenic nematodes symbiotic bacteria against phytophthora Phytophthora infestans (Mont.) de Bary has been shown. The features of metabolism products of entomopathogenic nematodes symbiotic bacteria influence on the catalase activity of potato tubers have been studied. The features of metabolism products of entomopathogenic nematodes symbiotic bacteria influence on the catalase activity of potato tubers have been studied. The using of metabolism products of entomopathogenic nematodes symbiotic bacteria increased the harvest, improved quality, suppressed the development of the phytophthora. Catalase activity decreased at treatment tubers with the metabolism products of entomopathogenic nematodes symbiotic bacteria.
