The effectiveness of the use of both biological and chemical means of protection of innovative varieties of winter soft wheat in the Left Bank Forest-Steppe of Ukraine has been proven. Without protection means, on average, the grain yield was 6.16 t/ha, with biological protection it increased by 6.6% (up to 6.58 t/ha), and the maximum value was reached with a chemical protection system, increasing by 12.0% (up to 6.86 t/ha). The difference between biological and chemical plant protection was minimal and amounted to 0.33 t/ha or 5.0%. Plant protection contributed to a significant increase in the mass of 1000 grains with the use of biological and chemical preparations. In the variant without protection, this indicator was on average 41.16 g, and in the variants with biological and chemical plant protection from harmful organisms, its increase was recorded by 2.2 and 3.2 g, respectively...
