Boyko Y. Physiological reasoning of an integrated action of biologically active substances in winter pea fields

In the dissertation work the separate and integrated action of different norms of herbicide of imidazolinone class MaxiMox was applied, which was applied to vegetative plants of winter peas of NS Moroz, with plant growth regulator Agriflex Amino and microbial preparation Optimize Pulse. For the first time in the Right Bank Forest-Steppe of Ukraine the effect of herbicide imidazolinone MaxiMox, plant growth regulator Agriflex Amino and microbial preparation Optimize Pulse was studied under different treatment methods (separately and in tank mixes) and it was found that Amino against the background of pre-sowing bacterization of seeds with the microbial preparation Optimize Pulse there is a decrease in the content of malonic dialdehyde in plants (up to 27%) with a simultaneous increase in glutathione-S-transferase (up to 66%) and enzymes of oxidoreductase - catalase, peroxidase and polypheno ), which is a sign of increased activity of antioxidant protection of plants. It was found that the integrated use of MaxiMox herbicide with plant growth regulator Agriflex Amino against the background of pre-sowing bacterization of seeds with the microbial drug Optimize Pulse showed the highest positive effect in agrophytocenosis of winter peas, as evidenced by increased yields and improved grain quality. The recommendations for production offer a combination of herbicide, plant growth regulator and bacterial preparation for growing winter peas.
