Abstract

Lack of knowledge in weed control techniques in oil palm cultivation practices can lead to decreased productivity. One of the herbicides that can be used to control weeds in oil palm cultivation is a mixed herbicide made from isopropylamine glyphosate 486 g/L and methyl metsulfuron 1 g/L. The use of mixed herbicides with two or more active ingredients can broaden the spectrum of weed control, reduce herbicide residues, slow the emergence of herbicide-resistant weeds, and reduce production costs. Therefore, this study aims to determine the effectiveness of mixed herbicides IPA glyphosate 486 g/L and methyl metsulfuron 1 g/L in controlling weeds in oil palm plants in the producing phase. This research was conducted at Bukit Nyomot oil palm plantation Subang Regency, Jawa Barat Province from February to May 2023. The experimental design used was Randomized Complete Block Design (RCBD) with 6 treatments and each treatment was replicate 4 times. The treatments are consisted of the application of mixed herbicides IPA glyphosate 486 g/L and methyl metsulfuron 1 g/L at doses of 1 L/ha; 1.5 L/ha; 2 L/ha; 2.5 L/ha; manual weeding; and control (no treatment). The results shows that the mixed herbicide IPA glyphosate 486 g/L and methyl metsulfuron 1 g/L at a dose of 1 L/ha to 2.5 l/ha is effective in controlling weeds in oil palm, such as Paspalum conjugatum, Ottochloa nodosa, Asystasia intrusa, Ageratum conyzoides, Chromolaena odorata, other weeds, and total weeds up to 12 Weeks After Application (WAA).
