Abstract

Istraživanje herbicidnog učinka kontaktnog (bentazon) i sistemičnog (imazamoks) herbicida primjenjenog u soji s utroškom škropiva od 200 l/ha i 400 l/ha na korove u soji provedeno je na pokušalištu Agronomskog fakulteta Šašinovec tijekom 2017. Utvrđivanje učinka provedeno je subjektivnom vizalnom metodom ocjenjivanja oštećenja korova (po skali od 0 do 100) 3, 7, 14, 28 dana nakon tretiranja korova. Nakon zadnjeg subjektivnog očitavanja obavljeno je objektivno utvrđivanje vrste, broja jedinki pojedine korovne vrste po m2 te utvrđivanje nadzemne mase korova po m2. Zadovoljavajući učinak na masu širokolisnih i uskolisnih korova postigli su tretmani utroškom vode od 400 l/ha. Bentazon je utroškom i 200 l/ha i 400 l/ha postigao zadovoljavajući učinak na redukciju nadzemne mase korovne vrste Ambrosia artemisifoliia, dok je imazamoks postigao zadovoljavajuči učinak s 400 l/ha.

Abstract (english)

Herbicidal effect research of contact (bentazon) and sistemic (imazamox) herbicide applied to soybean with spray consumption of 200 l / ha and 400 l / ha to the weeds in soybean is conducted in the Experiment station Šašinovec during 2017. Determining the herbicide effect was by visual subjective evaluation method of weed damage (by a scale from 0 to 100) 3, 7, 14, 28 days after treatment of weeds. After the last subjective evaluation method was conducted objective method evaluation was conducted by determining weed species, number of individual weed species per m2 and forming the overhead weight of weeds per m2. Satisfactory performance of the mass of broad-leaf and narrow-leaf weed treatments are achieved with water consumption of 400 l/ha. Bentazone with the consumption of 200 l/ha 400 l/ha by a satisfactory effect on weight reduction of weed species Ambrosia artemisifoliia, while imazamox achieved satisfactory performance with the water consumption 400 l/ha
