Abstract

Preduvjet za uspješan plasman kupusa na tržište su zdrave glavice. Pritom problem predstavljaju uzročnici bolesti i štetnici koji ih oštećuju i na taj način ih čine neprikladnim za tržište. Najznačajniji problem u zaštiti kupusa na području Knina u prethodnim godinama predstavljali su buhači (Phyllotreta spp.) i kupusni moljac (Plutella xylostella L.).
Pokus učinkovitosti insekticida iz različitih kemijskih skupina u suzbijanju najznačajnijih štetnika kupusa proveden je od srpnja do rujna 2018. godine. Pokus je bio postavljen na kupusu na području općine Biskupije, u Šibensko-kninskoj županiji. U istraživanje su uključena tri insekticida iz različitih kemijskih skupina: imidakloprid (neonikotinoid), dimetoat (organo-fosforni insekticid) i alfa-cipermetrin (piretroid). Pri očitavanju rezultata suzbijanja vizualno je pregledavano po 10 biljaka u svakoj parcelici. Na svakoj pregledanoj biljci zabilježen je ukupan broj listova, te broj odnosno postotak oštećenih listova. Po završetku vegetacije obavljeno je vaganje glavica kupusa na svim varijantama pokusa.
Insekticid „Rogor 40“ (dimetoat) iz skupine organo-fosfornih insekticida, pokazao je signifikantno bolju učinkovitost i nakon prvog i nakon drugog tretiranja od insekticida „Boxer 200 SL“ (imidakloprid) iz skupine neonikotinoida, te od insekticida „Fastac 10 EC“ (alfa-cipermetrin) iz skupine piretroida. Prosječna masa glavica je bila značajno veća kod biljaka koje su tretirane pripravkom „Rogor 40“ (dimetoat), za razliku od ostalih varijanata u pokusu.

Abstract (english)

A prerequisite for a successful placement of cabbage on the market are healthy cabbage heads. Plant disease agents and pests present a problem, as they damage them making them inadequate for the market. The most important problem in cabbage protection in the area of Knin in the recent years have been flea beetles (Phyllotreta spp.) and diamondback moth (Plutella xylostella L.).
A test of insecticide effectiveness from different chemical groups in control of the most important cabbage pests was conducted from July to September 2018. The test was performed on the cabbage in the municipality of Biskupija, in Šibenik-Knin County. The research included three insecticides from different chemical groups: imidacloprid (neonicotinoid), dimethoate (organic phosphate insecticide) and alfa-cypermethrin (pyrethroid). Upon reading the results, 10 plants were visually inspected in each plot of land. The total number of leaves was recorded on each inspected plant, as well as the number or percentage of damaged leaves. Upon the completion of vegetation, the results of the weighing of cabbage heads were released during all the test versions.
The insecticide “Rogor 40” (dimethoate) from the group of organic phosphate insecticides showed a significantly higher effectiveness both after the first and the second treatment compared with the insecticide “Boxer 200 SL” (imidacloprid) from the group of neonicotinoids and with the insecticide “Fastac 10 EC” (alpha-cypermethrin) from the group of pyrethroids. The average head size was significantly larger in plants treated with “Rogor 40” (dimethoate), as opposed to other variants in the test.
