Abstract

Ambrosia artemisiifolia L. (ambrozija) invazivna je korovna vrsta koja izaziva štete u
poljoprivredi i predstavlja javnozdravstveni problem. Zbog Europskog zelenog plana i razvoja
rezistentnih populacija, potrebno je istražiti razvoj novih strategija za suzbijanje ambrozije.
Potencijalno rješenje predstavljaju određene fenolne kiseline čiji je inhibitorni učinak
prethodno utvrđen u in vitro istraživanjima. Cilj ovog in vitro istraživanja bio je utvrditi
mogućnost primjene fenolnih kiselina u kombinaciji s reduciranim dozama herbicida
izoksaflutola. U preliminarnom in vitro pokusu korištene su tri fenolne kiseline (pkumarinska,
ferulinska i vanlinska) svaka u dozi od: 50, 100 i 200 x 10-7 mol s 0.05 l ha-1
herbicida izoksaflutol (1/8 doze od registrirane doze (x). Rezultatima ovog pokusa odabrana
je p-kumarinska kiselina (200 x10-7 mol) koja je u dose-response pokusu dodavana
reduciranim dozama izoksaflutola (x – 1/64 x). Rezultati istraživanja pokazuju da dodatak pkumarinske
kiseline značajno jače reducira duljinu radikule ambrozije u odnosu na iste doze
čistog herbicida (bez p-kumarinske kiseline) pri dozama herbicida reduciranim za 8 do 64
puta. Rezultati istraživanja potvrđuju mogućnost primjene reduciranih doza herbicida u
kombinaciji s p-kumarinskom kiselinom. Istraživanje bi trebalo nastaviti u in vivo uvjetima i
testirati folijarnu primjenu ove kombinacije herbicida i p-kumarinske kiseline.

Abstract (english)

Ambrosia artemisiifolia L. (ambrosia) is an invasive weed species that causes damage in
agriculture and is a public health problem. Due to the European Green Plan and the
development of resistant populations, it is necessary to investigate the development of new
strategies for the suppression of ragweed. A potential solution is represented by certain
phenolic acids whose inhibitory effect was previously determined in in vitro research. The
aim of this in vitro research was to determine the possibility of using phenolic acids in
combination with reduced doses of the herbicide isoxaflutole. In a preliminary in vitro
experiment, three phenolic acids (p-coumaric, ferulic and vanlinic) were added at a dose of
rescpetively: 50, 100 and 200 x10-7 mol 0.05 l ha-1 of the herbicide e (1/8 of the registered
herbicide dose ( x) Based on the results of this experiment, p-coumaric acid (200 x10-7 mol)
was selected to be was added in reduced doses of isoxaflutole (x – 1/64 x). The research
results show that the addition of p-coumaric acid significantly reduces the length of ragweed
radicles compared to the same doses of pure herbicide (without p-coumaric acid) at
herbicide doses reduced by 8 to 64 times. The research results confirm the possibility of
using reduced doses of herbicides in combination with p-coumaric acid. Research should be
continued in vivo to test the foliar application of this combination of herbicide and pcoumaric
acid.
