Abstract

Previous research has found a new type of herbicide made from fermented coconut water as the main raw material, containing organic materials, microorganisms, and is environmentally friendly. A series of tests need to be done to see its effectiveness. This study aims to determine the best formulation of herbicide in controlling weeds on land weeds and aquatic weeds in multiple locations. The experiment used a randomized block design, consisting of nine treatments of herbicide formulation (Unihaz) with three replications. The treatments were Unihaz 1, Unihaz 2, Unihaz 3, Unihaz 4, Unihaz 5, Unihaz 6, Unihaz 7, Unihaz 8 (glyphosate 2 kg ha-1) and Unihaz 9 (fermented coconut water). The results of the study concluded that the Unihaz 7 formulation was effective in controlling weeds both in dryland (land weeds) and in wetlands (water weeds) at various altitudes, and could control weeds above 90%. The herbicide formulation of Unihaz 7 was better at controlling weeds in paddy fields than the use of glyphosate at a dose of 2000 g ha-1

Abstract

This experiment aims to determine the effect of the herbicide Unihaz formulation on 30 types of weeds that are dominant in agricultural land. The target weeds consist of 10 types of grass weeds, 10 types of nut weeds and 10 types of broadleaf weeds. The tested weeds were sprayed with a herbicide of Unihaz formulation at a dose of 50 l / ha. The results of the study concluded that the herbicide of formulation Unihaz was effective in controlling the 10 weeds of the types of grass, namely Paspalum cunjugatum, Ischaemum timorence, Chrisopogon aciculatus, Brachiaria pospoloides, Echinochloa crus-galli, Imperata cylindrica, Axonopus compressus, Ischaemum globosa, and Cyrtococum oxyphyum. This herbicide was also effective in controlling the 10 weeds of the nut species, namely Cyperus brevifolius, Cyperus trachysanfos, Fimbristylis globulosa, Scleria sumatrensis, Cyperus aromaticus, Cyperus diformis, Scirpus mucronatus, Rhynchospora crystilis, Cyperus digitarius, and Fimbristylis malaceae. The herbicide of formulation Unihaz effectively controls eight types of broadleaf weeds, namely Urena lobota, Helyotis verticilata, Crassocephalum crapidiodes, Emilia sonchifolia, Asystasia intrusa, Mikania cordata, Hyptis suaveolens, and Borreria alata, and was not very effective in controlling the weeds Clidemia hirta, and Melastoma malabatricum.

Abstract

This study aims to determine the toxicity of the formulated herbicide concentration to non-target organisms (non-target) earthworms. The study was conducted from April to July 2021. The design used was a completely randomized design (CRD) with nine (9) herbicide concentrations (K) treatments, namely: K0 = control, K1 = 200 ppm concentration (0.2 ml/l water ), K2 = concentration of 400 ppm (0.4 ml/ l of water), K3 = concentration of 600 ppm (0.6 ml/ l of water), K4 = concentration of 800 ppm (0.8 ml/ l of water), K5 = concentration 1000 ppm (1.0 ml/ l of water), K6 = concentration of 1200 ppm (1.2 ml/ l of water), K7 = concentration of 1400 ppm (1.4 ml/ l of water), K8 = concentration of 1600 ppm (1, 6 ml/l water). Each treatment was repeated 3 times. The observed variables were mortality concentration 50 (LC50) for 96 hours, survival rate, mortality percentage and worm weight. This study concluded that the mortality concentration of 50 (LC50) for 96 hours from the formulated herbicide against earthworms was 600 ppm, while the 100% mortality occurred at the herbicide concentration of 1400 ppm. The lowest survival rate was found at a concentration of 1400 ppm, where at that concentration all the test worms died. Meanwhile, the highest survival rate after the herbicide was 200 ppm where the worm mortality was 20%. The higher the concentration of herbicide formulation given to earthworms, the higher the mortality rate and decrease in body weight.
