Herbology

The purpose of the study subject is to enable students to acquire knowledge of the science of herbology, weed concept, origin, distribution, biological properties, direct and indirect damage and to make decisions on weed control measures.

The aim of the study subject is to enable students to acquire knowledge about the weeds as regular competitors of agricultural plants and to be able to choose control measures to reduce their harmfulness.
