Plant Protection Institute

The Department of Herbology studies the biology of weeds and dynamics of alteration of weed associations; competitive relationships between weeds and crops; emergence and spread of weed biotypes resistant to main herbicides; optimization of weed control with regard to major agricultural crops.
