## 1 Introduction
Checking the combination ability of the chemical and plasma treatments is one of the objectives of this work. To test the concept of the compatibility of plasma and chemical treatments, in this work, we chose a tebuconazole-based seed disinfectant, \"Bunker\" (water suspension concentrate, content of tebuconazole is 60 g/L, JSC \"August\" Inc., Moscow, Russia ) [18]. There is a great deal of technical information on the use of the disinfectant, including in field studies [19, 20, 21, 22, 23]. The effect of disinfectants, including the disinfect \"Bunker\", on the quality of the winter wheat crop Moskovskaya 39 (_Tritcium aestivum_ L., variety Moskovskaya 39), cultivated for sowing seed purposes, was determined in [21] in a three-year experiment on plots of 25 m\({}^{2}\). The use of the disinfectant \"Bunker\" reduced the infection with root rot from 32-36% to 1-14%, accelerated the development of plants by 1-2 days, and increased the field viable germination by 11-14% and winter hardness by 3%, and the yield average for three years was 3.5 t/ha (control 3.09 t/ha). The action of a chemical disinfectant increased the strength of growth, the mass of 100 shoots, the height of the shoots, and the length of the primary roots. Throughout the entire growing season, \"Bunker\" protected plants from root rot. Long-term protection of the plant from diseases, due to the chemical stability of the agent, is also noted in the work [22]. On the seedlings of spring soft wheat Tulunskaya 12 (_Triticum aestivum_ L., variety Tulunskaya 12) [20] and soft winter wheat Irkutskaya (_Triticum aestivum_ L., variety Irkutskaya) [22], the effect of various concentrations of the \"Bunker\" disinfectant was studied. On both spring and winter wheat, with an increase in the concentration of the disinfectant, an increase in the growth-inhibiting effect was observed, but when exposed to spring wheat, the growth of both the aboveground and underground parts of the plant slowed down, and when exposed to winter wheat, the growth of the aboveground one slowed down and the growth of the underground one accelerated. The relative frost resistance of etiolated seedlings of Irkutskaya winter wheat became larger with the increase in the concentration of the disinfectant to 1.5 L/t from 0.5 L/t [19]. For the \"Bunker\" disinfectant, a dose of 1.5 L/t is designated as optimal for Irkutskaya winter wheat in [23]. At present, the full range of negative consequences has not been determined yet. The need to reduce the amount of chemical plant protection products used in general, and tebuconazole, in particular, is associated with the many undesirable effects that they have on the environment. Research to determine these consequences is being actively carried out [24; 25; 26]. There are other methods of presowing preparation aimed at increasing the resistance of plants: hydropriming, osmoriming, biological methods, the use of phyto hormones, and others [27; 28]. Among them, some technologies have great environmental potential and efficiency. It is also necessary to take into account the cross action [28]. This means that the action of certain stress during seed preparation provides resistance not only to this stress but also to other possible stresses acting on plants throughout the entire process of development. This concept fits the data that indicate that plasma treatment and other electrophysical technologies can provide resistance to various stresses (for example, drought, salinity, and phytopathogenic load [29]). However, under natural conditions, with a decrease in daily temperature, winter crops undergo natural hardening at a low temperature and acquire resistance to shock freezing. Pre-hardening by plasma treatment can prevent cold hardening. It is also known that the use of a tebuconazole-containing disinfectant does not interfere with cold hardening, which imitates these natural conditions [19; 22].
