Investigations on biological control of weeds in Romania

Abstract

Conducted and systematic investigations on the biological control of weeds were not carried out both in this country and within the Agronomy Institute of Cluj-Napoca, namely by the Departament of Entomology (T. Perju 3-6). In 1985-1987, as a result of investigations led by the authors, there were traced down the troublesome weeds in the main agroecosystems as well as the carriers and phytophagous insects contributing spontaneously to the reduction of weed thickness in the crops and to reducing their spreading ability.
