Sanin O. Physiological features of the combined use of fungicides and nutrients to protect winter wheat from fusarium wilt.

For the first time, the presence and harmfulness of Fusarium spp. in the regions of Ukraine have been identified. The role of phenylpyrrole, triazoles, strobilurins and SDHI fungicide classes in the control of Fusarium root rot of wheat has been determined. SDHI has been shown to increase the accumulation of phosphorus by winter wheat seedlings, which may be associated with increased levels of root rot control and promote better overwintering of crops. The influence of fertilizers and fungicides on the accumulation of chlorophyll by plants of highly productive varieties of winter wheat was determined. Data on the nitrogen content in the grain of highly productive crops of winter wheat under the action of fungicides and foliar fertilizers in protection against fusarium wilt were obtained. It has been shown for the first time that the use of selective compositions against fusarium wilt during the growing season is a factor in increasing the efficiency of nitrogen use and increasing the levels of redistribution of nitrogen into grain. It is shown that the direct effect of fungicides of phenylpyrrole, triazole, strobilurin and SDHI classes on changes in the elemental composition of winter wheat grain is limited.
