Abstract
Oil palm (Elaeis guineensis Jacq.) is a plant
from the plantation sector with high economic value. A severe problem in oil
palm cultivation, especially in the immature plant phase, is the presence of
weeds. Weeds in oil palms in the immature plant need to be controlled because,
in this phase, oil palms have quite open spaces between plants, which results
in weeds growing quite dominantly. One of the controls that can be carried out
is chemical control using herbicides. Paraquat dichloride is a contact
herbicide with a mode of action that inhibits photosystem I. It is included in
contact herbicides, is non-selective, and is applied post-emergence. This
research will run from December 2023 to April 2024 at the Palm Oil Plantation,
Kec. Pakenjeng, Kab. Garut. The treatment design used a Randomized Experimental
Design with seven treatments, namely: Paraquat dichloride 276 g/L dose 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). Differences between treatments were tested using the F
test and further tested using the Duncan test with a significance level of 5%.
The research results show that application of the herbicide Paraquat dichloride
starting from 1.5 l/ha can control weeds Synedrella nodiflora, Cyperus
rotundus, Oplismenus compositus, Pueraria montana and weeds up to 8 w
in total. Meanwhile, observations of the Urena lobata and Strachytarpheta
jamaicensis weeds showed no significant differences between the
control and manual weeding treatments.
