Mogućnost primene nekih tehničko-tehnoloških metoda u suzbijanju korova u održivoj proizvodnji

Abstract

Održiva poljoprivredna proizvodnja je sve popularnija i zahteva formiranje alternativnih metoda gajenja biljaka. Posebna pažnja usmerava se na istraživanje novih metoda u zaštiti bilja za suzbijanje korova jer je zabranjena upotreba sintetički proizvedenih herbicida. Suštinu zaštite biljaka čine preventive mere kao što su biofizičke metode uz primenu različitih bioloških sredstava za zaštitu. Cilj rada je da se prikažu istraživanja vršena radi iznalaženja novih mera u zaštiti bilja kod suzbijanja korova. Razvoj biofizičkih metoda može se ogledati u efikasnosti upotrebe aparata naponom od 25 kV, ekspozicije 1,5 s na ambroziju posle žetve pšenice. Prvi rezultati bili su vidljivi posle 20 minuta, a ukupan broj biljaka u tretmanu bio je uništen posle 5 dana. Takođe, ispitivana je biološka efikasnost bioherbicida na bazi pelargonijske kiseline u suzbijanju različitih korova u koncentraciji 2, 4, 6 i 8% u 4l vode. Koncentracija od 8% je najbrže i najuočljivije delovala na uvenuće ispitivanih korova.

Sustainable agricultural production is becoming increasingly popular and requires the formation of alternative methods of plant cultivation. Special attention is directed to the research of new methods in plant protection for combating weeds, as it is forbidden to use synthetically produced herbicides. The essence of plant protection consists of preventive measures such as biophysical methods, with the application of various biological means of protection. The aim of this paper is to present the research performed in order to find new measures in plant protection in weed control. The development of biophysical methods can be reflected in the efficiency of using the apparatus with a voltage of 25 kV, exposure of 1.5 s, on ambrosia after wheat harvest. The first results were visible after 20 minutes, and the total number of plants in the treatment was destroyed after 5 days. Also, the study is the biological efficiency of bioherbicides based on pelargonium acid in controlling various weeds in a concentration of 2, 4, 6 and 8% in 4 l of water. The concentration of 8% had the fastest and best effect on the wilting of the examined weeds.
