In this articlest is refl ected influence of worm’s compost on cultivation of maize and the level of smut’s pollution (Ustilaginalis) of  plants  in the first, in the second and third year of use of fertilizer. As a result of researches it has been established, that inclusion of worm’s compost in soil (4t/ha) has reduced in 2,5 times corn pollution of smut in the fi rst year of use of fertilizer. The plants which have been grown up with use  of  worm’s  compost (for the second and third year of action of fertilizer), have not been infected of smut, and the cultures which have been grown up on a natural background, have been infected of smut,  corresponding on 2,58 % and 1,15%. Harvest of cobs on lots worm’s compost fund, increased by 21.05% -35.09% compared with the harvest from the control group. So, use of worm’s compost diminished degree of contamination of maize of smut  and increased harvest cobs.
