Biology, occurrence and control of weeds in crops of root crops
 CHODL, Tomáš
The aim of the present diploma thesis is to widen knowledge of the chemical regulation of weeds in row crops. To establish the effectiveness of herbicides, we set up a small lot at a carefully chosen spot in the potato-growing region near Strakonice. We conducted a comparison of the effects of three herbicide combinations on two potato varieties (Red Anna, Laura). Two combinations proved pre-emergent (Afalon 45 SC+Command 36 SC; Sencor 70 WG+Command 36 SC), one post-emergent (Titus 25 WG). Subsequently, we evaluated economic costs on weeds regulation and suggested preliminary measures to be taken.
