Abstract
The article examines the elements of the phytosanitary adaptive technology of potato cultivation in the conditions of the Trans-Urals. Prospective varieties of potatoes have been studied. The yield increase for new varieties varied from 3.4 t/ha Colombo to 4.9 t/ha Cavalier, due to the resistance of new varieties to diseases. The data on the protective measures taken in planting potato varieties are presented. This is the use of Akiba disinfectants (imidacloprid - 500 g/l) - 0.1 l/t and King Combi (acetamiprid + fludioxonil + cyproconazole, 100 + 34 + 8.3 g/l) - 0.4 l/t in the fight against the Colorado potato beetle and beetle larvae clickers - wireworms, and also identified the best options for integrated protection of potatoes, which made it possible to save the harvest and increase the yield from 3.9 t/ha to 9.9 t/ha for the Mia variety and from 4.0 t/ha to 11.25 t/ha for the variety Itzil. The maximum increase was found in the variants of complex protection of potatoes from pests and diseases in the conditions of the Trans-Urals. The use of new varieties and plant protection products are important elements of potato cultivation technology.
