Abstract

The oil palm plant which has the Latin name Elaeis guineensis Jacq. is one of the main plantation commodities in Indonesia. The growth of weeds on oil palm cultivation land causes competition for growth facilities and affects the growth of oil palm plants (TBM). One of the active ingredients of herbicides used to control weeds in TBM oil palm plantations is metsulfuron methyl herbicide. This study aims to determine the effective dose of 20% metsulfuron methyl herbicide in suppressing weed growth in TBM oil palm plants, to determine changes in the composition of weed species that grow after the application of metsulfuron methyl herbicide, to determine the effect of phytotoxicity on TBM oil palm plants due to herbicide application. This research was conducted in an oil palm plantation in Braja Lebah Village, Braja Selebah District, East Lampung Regency and the Laboratory of Weed Science, Faculty of Agriculture, University of Lampung from August to December 2022. This study used a Randomized Block Design (RAK) with 6 treatments 6 and 4 replications with metsulfuron methyl dose as follows 15; 20; 25; 30g/ha; mechanical weeding and control. The homogeneity of the variance of the data was tested by Barlett's test and the additivity of the data was tested by using the Tukey test and the difference in the mean treatment was tested by the Least Significant Difference (LSD) test at the 5% level. The research results show that; (1) The herbicide methyl metsulfuron 20% at a dose of 15 – 30 g/ha is effective in controlling the growth of total weeds, the dominant weeds Asystasia gangetica and Praxelis climatidea, Boreria alata, Melastoma malabathricum and Richardia brasiliensis up to 12 MSA; (2) Metsulfuron Methyl Herbicide 20% at a dose of 15 – 30 g/ha caused a change in weed composition at 4, 8, and 12 MSA; (3) The application of 20% metsulfuron methyl herbicide at a dose of 15–30 g/ha does not cause poisoning in TBM oil palm plants. Keywords : efficacy, herbicide, oil palm, metsulfuron methyl

Abstract

Chinese sprangletop (Leptochloa chinensis) reproduces sexually and vegetatively. This weed has a lot of seeds, is easy to grow, and adapts well to dry and wet land. Proper control is needed. Hoorahgrass extract can be used as an alternative to control weeds. Hoorahgrass (Fimbristylis miliacea) is a group of enigmatic weeds that contain allelochemical compounds. The aims of this research were to determine the effect of the source and concentration of hoorahgrass extract on the germination and growth of chinese sprangletop. This research carried out at the Greenhouse Integrated Field Laboratory, Faculty of Agriculture, University of Lampung from December 2022 to February 2023 using a Randomized Block Design (RAK) with 2 factors and 4 replications. The first factor was the extract component of hoorahgrass root (A1), shoot (A2) and mixture (A3), and the second factor was hoorahgrass with a concentration of 0% (B0) or (control), 2.5% (B1), 5% (B2 ), 7.5% (B3), 10% (B4). The data obtained were analyzed using analysis of variance, and first tested for homogeneity of variance using the Bartlett test, followed by the least significant difference test (LSD) at the 5% level. Based on the research results, hoorahgrass extract concentration of 5 to 10% was most effective in reducing seed germination rate, seed germination speed, chinese sprangletop root length and total dry weight. A concentration of 10% was most effective for reducing the height of chinese sprangletop. Keyword: Fimbrisylis, concentration, extract, bioherbicide, Leptochloa

Abstract

The growth of weeds in immature cocoa plants is highly susceptible to competition for water, nutrients, and light, which can disrupt the growth of cocoa plants. Efforts to manage cocoa cultivation include weed control using the chemical herbicide paraquat dichloride, a non-selective contact herbicide. This study aimed to determine the effective dosage of paraquat dichloride for controlling weeds in immature cocoa plants, changes in weed composition, and phytotoxicity on immature cocoa plants following the application of paraquat dichloride. The study was conducted in Talang Sepuh Village, Talang Padang Sub-district, Tanggamus Regency, from March–May 2024. The research employed a Randomized Complete Block Design (RCBD) with six treatments and four replications. Treatments included paraquat dichloride at doses of 414 g/ha, 552 g/ha, 690 g/ha, 828 g/ha, mechanical weeding, and a control group (no weed control). Data variance homogeneity was tested using Bartlett's test, and data additivity was evaluated with Tukey's test. If the assumptions were met, the mean difference was analyzed using the Least Significant Difference (LSD) test at a 5% significance level. The results indicated that paraquat dichloride at doses of 414–828 g/ha effectively controlled total weeds, broadleaf weeds, and dominant weeds (Eleusine indica, Praxelis clematidea, and Synedrella nodiflora). Meanwhile, doses of 552–828 g/ha were effective in controlling grass weeds and dominant weeds (Ottochloa nodosa and Asystasia gangetica). The application of paraquat dichloride did not alter weed composition and did not cause phytotoxic effects on immature cocoa plants..Keywords : Herbicide, Paraquat dichloride, Weed, Immature cocoa.

Abstract

This study aimed to evaluate the efficacy of single herbicides saflufenacil, trifludimoxazin, and their mixtures, as well as to determine the interaction characteristics of the saflufenacil and trifludimoxazin combination in weed control. The experiment was conducted in a Plastic House in Natar District, South Lampung Regency, from April to May 2025. A single-factor Randomized Block Design (RBD) was applied with 54 treatment combinations, consisting of 3 herbicide types at 6 dosage levels: single saflufenacil (0, 25, 50, 100, 200, and 400 g/ha), single trifludimoxazin (0, 12.5, 25, 50, 100, and 200 g/ha), and their mixtures (0, 37.5, 75, 150, 300, and 600 g/ha). Treatments were applied to 3 weed species: the broadleaf Ageratum conyzoides, the grass Digitaria ciliaris, and the sedge Cyperus kyllingia. Each treatment was replicated 6 times. The interaction analysis of herbicide mixtures was carried out using the Multiplicative Survival Model (MSM), since the two herbicides have different modes of action. The results showed that: (1) single saflufenacil was only effective in controlling Ageratum conyzoides at (25-400 g/ha). Single trifludimoxazin effectively controlled Ageratum conyzoides (12.5-200 g/ha), Digitaria ciliaris (200 g/ha), and Cyperus kyllingia (50-200 g/ha). The mixture of saflufenacil+trifludimoxazin effectively controlled Ageratum conyzoides (37.5-600 g/ha), Digitaria ciliaris (75-600 g/ha), and Cyperus kyllingia (300-600 g/ha). (2) With an expected LD50 value of 83.36, which was higher than the observed LD50 value of 67.33, a co-toxicity coefficient of 1.24 (>1) was obtained, indicating that the mixture exhibited a synergistic effect.
