Abstract: The purpose of the laboratory studies was to establish the effect of disinfectants on the germination energy and laboratory germination of seeds of soft spring wheat, spring barley and peas. For comparison of the action of disinfectants on germination and seed germination of the three crops used the following products: Deposit and Maxim peas, Scarlet, stinger Trio, benefit, Maxim, Extrasol on wheat and barley at the recommended dose, just 21, for taken control variant with distilled water. It was found that the use of the drug stinger Trio significantly increased the energy of seed germination in spring wheat varieties Catherine and spring barley varieties sonnet and chepelev Memory. Preparations used on pea seeds, in General, increased laboratory germination on all variants. The most effective drugs that protect crops from diseases are drugs: Maxim and tank mixture Extrasol + Maxim. Treatment with preparations on spring wheat Maxim + Extrasol allowed to increase field germination from 1‰ to 26‰ compared to the control. The maximum yield on the variety Catherine ranged from 4.0 t / ha (Scarlet) to 4.5 t / ga (Maxim + Extrasol). The greatest effect of increasing the yield was observed on spring barley in varieties of the drug benefit (+0.6 t / ga). On peas in varieties Krasnoufimsky 11 maximum yield obtained on the version of Maxim (1.6 t / ga).
