The new modern preparation – protein growth stimulant – was generated in
accordance with technology of employees of Saint-Petersburg ITMO University and SaintPetersburg State Agrarian University. Biological activity of the preparation was determined by
measurements of 20 indicators of the wheat productivity. In addition, 16 indicators of different
types of pathogenesis were determined. These can be formed at distribution of Helminthosporium
root rot, wheat rust species, powdery mildew and wheat leaf blotch. The use of the protein growth
stimulant promoted increase of potential yield in 80% of samples. In comparison with the control,
15 wheat varieties, treated with the preparation, showed an increase in the main productivity
indicators: the length of the spike, the number of spikelets per spike, the weight of 1,000 grains,
the productive tilling capacity and the general bushiness. The intensity of Helminthosporium root
rot development decreased 11.9% (it was found in 53.3% of samples) and the wheat leaf blotch
by 15.6% (in 66.7% of samples). The wheat brown rust development intensity decreased
insignificantly (3.6% compared to the control). In the same time, values of the pathogen pustule
area decreased at average by 79.8%. There was an increase in total nitrogen in wheat leaves at
92% of samples. As was revealed, the effectiveness of the protein growth stimulant largely
depends on the wheat variety. To conclude, the prospect of using the new effective protein growth
stimulant to increase productivity of wheat and protection from diseases was shown.
