Abstract
Grain crops are the source of the initially necessary raw materials for most bakery products, as well as a food product for livestock farming. Grain is of inherent strategic importance to the country or is considered as a factor in the state’s food reserves. The problem of increasing grain production remains relevant to this day; the reason is the high value of grain products with the subsequent demand for these products. There are many factors reducing wheat productivity, the most significant being diseases. The main weapon in the fight against wheat diseases are fungicides of various spectrums of action, including Soligor. Research has shown that with the use of the Soligor fungicide at a consumption rate of 0.4 l/ha to 0.6 l/ha, the percentage of leaf rust development decreased to 0.7 %. Biological effectiveness was 92.5 %. At a consumption rate of 0.5 l/ha of the Soligor preparation, the development of leaf rust is reduced to 0.9 %, with biological efficiency – 82.5 %. By the number of grains in an ear – 23.2 pcs. – and the weight of 1000 seeds is 33 g. – the indicators were higher at a consumption rate of 0.4 l/ha. The number of productive stems was higher at a consumption rate of 0.6 l/ha with an indicator of 261 pcs/m2. On wheat crops with an application rate of 0.6 l/ha, the biological yield was higher by 1.2 c/ha than at a rate of 0.4 l/ha, 18.1 c/ha and 16.9 c/ha, respectively. Keywords: fungicide, application rates, yield, Soligor, efficiency.
