Abstract
Krumpir je jedan od tri najznačajnije kulture u Republici Hrvatskoj. Cilj ovog rada je prikazati obavljenu zaštitu krumpira na OPG – u Košić Ivica u 2018. godini, gdje je ujedno i krumpir najzastupljenija kultura. Važnu ulogu u zaštiti krumpira ima praćenje agroklimatskih uvjeta, a zaštita se obavljala kemijskim preparatima (herbicidima, insekticidima i fungicidima) prema pravilima struke. Korovi se suzbijaju poslije sjetve, a prije nicanja sa selektivno zemljišnim herbicidima (metobromuron, pendimetalin i klomazon). Prskaju se tripleks diznama od 0.4 mm i pritiskom 2.5 bara. Zaštita krumpirove zlatice obavljena je u dva tretiranja s insekticidom (tiakloprid). Prilikom svakog tretiranja korištena je jednaka doza (tiakloprid) od 0,1 l/ha. Zaštita od uzročnika bolesti obavljena je četiri puta s fungicidima (dimetomorf, propamokarb, amisulbrom i ciazofamid). Radi uspješne aplikacije i odabira fungicida nije se pojavila plamenjača krumpira kod ranih sorata krumpira, a kod kasnijih radi njezine pojave je provođena desikacija cime. Iako je 2018. godina bila sušna sa vrlo visokim temperaturama zraka, a samim time nepovoljna za rast i razvoj krumpira, prinosi su bili relativno visoki, od 35 do 45 t/ha.Potato is one of the three most important cultures in the Republic of Croatia. The aim of this paper is to show the potato protection at OPG Košić Ivica in 2018, where potatoes are the most represented. An important role in the protection of potatoes is the monitoring of agro-climatic conditions, and the protection is done by chemical preparations (herbicides, insecticides and fungicides) according to the rules of the profession. The weeds are suppressed after sowing, and prior to the emergence of selective herbicides (metobromuron, pendimethalin and clomazone). Sprayed triplex diaphragms of 0.4 mm and 2.5 bar pressure. The protection of potato grain was done in two insecticide treatments (thiakloprid). At each treatment, an equal dose (thiacloprid) of 0.1 l / ha was used. The protection from the cause of the disease was done four times with fungicides (dimethomorph, propamocarb, amisulbrom and cesium amide). For the successful application and selection of fungicides, potato flakes did not appear in early potato crops, but in the latter case, the desiccation of peppers was performed. Although in 2018 it was dry with very high air temperatures and therefore unfavorable for potato growth and development, the yields were relatively high, from 35 to 45 t / ha
