Abstract

Weeds are one of the obstacles to the growth of lowland rice cultivation which can reduce the quantity of rice yields so that weeds need to be controlled. This study aims to determine the effect of metamifop 150 g/L herbicide to control weeds in lowland rice cultivation. The experiment was carried out on paddy rice cultivation land in Langansari Village, Tarogong Kaler Cipanas District, Garut Regency, West Java, from November 2022 to February 2023. The experiment used a Randomized Block Design (RBD) with six treatments and four replications. The experiment consisted of four treatments with the active ingredient metamifop 150 g/L at a dose of A: 5.4 ml, B: 7.2 ml, C: 9.0 ml, D: 10.80 ml, E: manual weeding treatment and F : control treatment with no weed control. The results showed that the application of the herbicide with the active ingredient metamifop 150 g/L at a dose of D: 10.80 ml was able to suppress weed growth but the results were not significantly different from the dose of 5.4 ml which was the lowest dose to reduce weed resistance and plant residues so that dose A : 5.4 ml able to suppress the growth of weeds Echinochloa crusgalli, Monochoria vaginalis, Cyperus rotundus, Spenochlea zeylanica, Panicum repens, Cyperus difformis and total weeds.

Abstract

Weeds are nuisance plants that grow in unwanted areas and inhibit the growth of paddy rice cultivation, which can reduce the quantity of rice yield Therefore, weeds need to be controlled. This study aims to determine : 1) the effect of using 10% Ethyl pyrazosulfuron herbicide on the growth of Rojolele Srinuk variety of paddy rice (Oryza sativa L. var. Rojolele Srinuk) and 2) the correct dose of 10% Ethyl pyrazosulfuron herbicide for the growth of Rojolele Srinuk variety of paddy rice. This research was conducted in Langensari Village, Tarogong Kaler District. The research was conducted from November 2022 to February 2023. This study used a Randomized Group Design (RGD) with seven treatments and four repetitions, including 10% Ethyl pyrazosulfuron herbicide treatment at a dose of 150 g/ha (0.18 g/12 m2 ), 225 g/ha (0.27 g/12 m2 ), 300 g/ha (0.36 g/12 m2 ), 375 g/ha (0.45 g/12 m2 ), 450 g/ha (0.54 g/12 m2 ), manual weeding and control. The results showed that the use of 10% Ethyl pyrazosulfuron herbicide at a dose of 150 g/ha (0.18 g/12 m2 ) - 450 g/ha (0.54 g/12 m2 ) did not cause phytotoxicity or symptoms of poisoning to Rojolele Srinuk variety of paddy rice plants. Then, the use of the herbicide Ethyl pyrazosulfuron 10% affects the number of tillers of rice paddy varieties Rojolele Srinuk. The most effective dose of 10% Ethyl pyrazosulfuron herbicide in the growth of Rojolele Srinuk rice paddy is a dose of 450 g/ha (0.54 g/12 m2 ).
