Abstract
Oil palm (Elaeis guineensis Jacq.) is a
plantation commodity that has great prospects in Indonesia because it
contributes to the country's foreign exchange and national economic
development. Oil palm productivity is often hampered by the presence of weeds,
especially in the immature plant phase. This study aims to evaluate the
effectiveness of the herbicide Isopropyl Amine Glyphosate 486 g/l in
controlling various types of weeds on immature plant phase oil palm. This
research was conducted at an oil palm plantation in Pakenjeng District, Garut
Regency, West Java Province, from December 2023 to April 2024. The experimental
design used was a Randomized Group Design (RAK) with four replications and
seven herbicide dose treatments, namely a dose of 1.5 l/ha; 2.0 l/ha; 2.5 l/ha;
3.0 l/ha; 3.5 l/ha; Manual weeding; and control (without treatment). The
research results showed that a dose of 1.5 – 3.5 l/ha of Isopropyl Amine
Glyphosate herbicide 486 g/l was effective in controlling the weeds Synedrella
nodiflora, Urena lobata, Cyperus rotundus, and Pueraria montana. However, this
herbicide is less effective against Stachytarpheta jamaicensis and is only
effective against Oplismenus compositus up to 4 weeks after application
(weeks). Overall, this herbicide application showed effective total weed
control at 4, 8, to 12 weeks without causing phytotoxicity in immature plant
phase oil palm plants. This research concludes that the herbicide Isopropyl
Amine Glyphosate 486 g/l can be used as an efficient weed control method in
immature plant phase oil palm cultivation.
