The research deals with the composition of current plant species in agrophytocenosis and the distribution of individual weed species in agricultural crops. The distribution area and harmfulness of Avena sp. has been determined at different density of spring crop population. The relationship between phytopathological conditions of weeds and grain crops has been investigated. Seed dormancy period and the possibility of its interruption by light impulses have been studied and tested. The application efficiency of several herbicides has been tested in grain crops, technical crops and on grassland. The results of investigations and tests are discussed.
