Field resistance to phytopathogens and grain productivity of spring wheat when using fungicides, biological preparations and microelements in Priamurye

Protective agro-complexes, which include the use of fungicides, biologically active substances and copper-containing preparation, have been studied. Their efficiency in increasing the resistance of spring wheat to helminthosporiosis and septoriosis has been established. The increase of photosynthetic activity of plants in crops and the growth of grain productivity of agricultural crop have been noted.
