20.500.12556/DKUM-96033 The influence of alternative weed control under "Sauvignon Blanc" vines on grape characteristics and environmental footprint Chemical control of weeds with the herbicide glyphosate under vines in the vineyards is currently easy, effective, and cheap. There are currently no completely equivalent alternative herbicides or suitable mechanical control methods that have the same efficacy in suppressing weeds under vines in vineyards as glyphosate. Therefore, in this research, we tested two alternative technologies for controlling weeds under the vines as a counterweight to the predominant control approach with the herbicide glyphosate: (1) chemical control with pelargonic acid, acetic acid, and the plant extract-based fertilizer Stopeco® with herbicidal action, and (2) mechanical control with a combined tool consisting of a rotary star tiller and finger weeder. A comparative analysis was conducted on time and fuel consumption, the extent of the carbon footprint, grape yield, and quality, which showed that the tested alternative methods of weed control were not comparable to the herbicide glyphosate in terms of effectiveness in weed suppression but were comparable at grape yield. In our trial, at the number of treatments we performed, differences in environmental footprint between different treatments were significant (glyphosate variant 10.55–11.21 gha anno−1; other variants 7.48–8.08 gha anno−1). Alternative mechanical and chemical methods need to be applied at least three to four times a year to achieve results comparable to those from two applications of glyphosate. For this reason, it is possible that, in the case of a slightly increased number of passes by mechanical tools or a slightly increased number of sprayings with alternative preparations to reach the efficacy level of glyphosate treatments, the foot print parameter, CO2 emissions and global warming potential (GWP) parameter in alternative treatments would no longer be more favorable than when using the herbicide glyphosate twice a year. glyphosate pelargonic acid acetic acid vineyard weed control rotary star tiller footprint true true true MDPI Angleški jezik Angleški jezik Znanstveno delo 2025-11-25 03:10:55 2025-12-17 14:11:10 2025-12-18 03:12:17 0000-00-00 00:00:00 2025 0 0 str. 1-25 Iss. 11, [article no.] 2666 Vol. 15 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-11-10 2025-11-18 2025-11-20 632.9:634.836 258098179 10.3390/agronomy15112666 2073-4395 https://www.mdpi.com/2073-4395/15/11/2666 1 fad281a7-c9a3-11f0-8fc7-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=200870 agronomy-15-02666-v2_(1).pdf agronomy-15-02666-v2_(1).pdf 1 89FB6AD940B718842293EDECE7342A30 4ae1011860d3274ce0bf58bcc6c07dad9a466564bb3e3053fbde342058b01f73 eaca651a-c9e2-11f0-8fc7-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=200877 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
