Prvi dokaz rezistentnosti korova na herbicide u Hrvatskoj, ujedno i prvi u bivšoj državi, datira iz 1982. kad je pokusima u stakleniku i u polju u Severinu (Bjelovar) dokazana rezistentnost nekih biotipova lobode bijele (Chenopodium album L.) na atrazin. U istim pokusima dokazana je i unakrsna rezistentnost (cross‐resistance) na simazin, terbutilazin, cijanazin, ametrin i prometrin. Kasnije, početkom 2000‐tih utvrđena je rezistentnost šćira oštrodlakavog (Amaranthus retroflexus L.) i pelinolisnog limundžika (Ambrosia artemisiifolia L.) na više lokacija u Hrvatskoj. U radu je kronološki prikaz tiskanih radova hrvatskih autora koji se odnose na problematiku rezistentnih korova na herbicide, uključujući provedene projekte i diplomske radova. Dan je kritični osvrt na aktivnosti koje se na nacionalnom nivou poduzimaju u ovoj problematici.The first Croatian report of triazine resistance in an initially triazine sensitive weed species was in 1982 by Ostojić et al for Chenopodium album in Severin (figure 1). During the early 1980s, the atrazine resistant biotype of Ch. album was found in field corn where atrazine or simazine had been used traditionally. The next documentation of atrazine resistant A. retroflexus and A. artemisiifolia biotype was by Flegar and Novak 2005, Flegar, Ostojić, Barić i Galzina 2006. Seeds were collected from different locations and resistance to atrazine was confirmed in glas‐house studies. Further comparative tests its cross‐resistance to several triazine herbicides was confirmed
