TECHNIQUES PHYTOSTEROLEMIA TOMATO SEEDLINGS WITH THE USE OF ELECTROLYZED WATER AND USING IT AS THE BASIS OF SOLUTIONS
The urgent problem to be solved by the present research is the development of en-vironmentally friendly technologies that reduce the harmfulness of phytopathogens and pests when growing vegetable products in a protected ground. The purpose of the research was to quantify the effects of using electrochemically treated water to suppress phytopath-ogenic microflora and to contain diseases of tomato seedlings. The research methodology is based on an experiment. When substantiating the methods of using electrochemically treated water, the necessity of taking into account the source of infection and evaluating the technologically feasible value of the electrochemically initiated shift of the redox po-tential was taken into account. The studies obtained experimental data confirming the fea-sibility of using water with an electrochemically initiated shift of the redox potential for spilling the soil before sowing seedlings both in monotechnology and when used together with the microbiological preparation bisolbifit. It was established that the use of water with an electrochemically determined shift of the redox potential for soil disinfection al-lows 1,5-2,7 times reduction in the number of seedlings affected. Irrigation of tomato seedlings gives a similar effect, but with significantly increased costs of electrochemically treated water. The best performance was obtained when using water with an electrochemi-cally determined shift of the redox potential of +800 mV. The use of electrochemically treated water to prepare a solution of bisolbiphyte ensured a higher activity of suppressing phytopathogenic microflora in comparison with monotechnologies both in treated water and in biolbiphite: the number of affected seedlings decreased by 20-33%. It was found that the most effective is the alternate use of anolyte (+800 mV) for disinfection of the soil and spilling with a solution of the drug bisolbifit, which together ensured the spread of seedling diseases at a level of 0,8-2,0%.
