Description
| - Polní pokusy byly založeny v letech 2000 - 2002 s cílem sledovat vliv vybraných herbicidů na plevele a výnos a kvalitu hlíz brambor. Byla zjišťována hmotnost plevelů z jednotky plochy u těchto druhů: Brassica napus, Galium aparine, Chenopodium album, Polygonum convolvulus a Viola arvensis. Sledovány byly tyto účinné látky:clomazone: metribuzin, linuron a terbuthylazine s terbutrynem. Dominantním plevelem byla ozimá řepka. Metribuzin plevele redukoval na 84,5% (87,9% plevelnou řepku), 95,8 % linuron (94,9 %) a 90,8 % (88,4 %) terbuthylazine s terbutrynem. Výnos hlíz byl na neošetřené variantě průkazně nižší mezi ostatními průkaznost zjištěna nebyla.Redukce výnosu mezi neošetřenou kontrolou a variantou s nejvyšším výnosem byla 44 % v roce 2000, 41% v roce 2001 a 48% v roce 2002.

- Field trials conducted during 2000-2002 studied the effect of selected herbicides on weed control efficiency and yield and potato quality parameters. Total weed fresh weight was measured in g.m-2 and from this weight of following species was determined: winter Brassica napus, Galium aparine, Chenopodium album, Polygonum convolvulus and Viola arvensis. Following active ingredients were tested using application with clomazone: metribuzin, linuron and terbuthylazine with terbutryn. Winter Brassica napus was dominant weed. It was 84,5 % (87,9 % efficiency against winter Brassica napus) for metribuzin, 95,8 % for linuron (94,9 %) and 90,8 % (88,4 %) for terbuthylazine with terbutryn. Tuber yield was significantly lower on untreated variants, no significant differences were found among individual active ingredients. Yield reduction (between the herbicide-treated variant with the highest yield and the control untreated variant) was 44 % in 2000, 41 % in 2001 and 48 % in 2002.
