Abstract

The aimed of this research was to know the effectiveness of mixing herbicides with active ingredient atrazin and mesotrion in controlling weeds and know the mixture characteristic. This research conducted in the plastic garden house private in Natar, South Lampung and in the Weeds laboratory of Agriculture faculty, Lampung University from June until July 2013. This Research arranged in a Randomized Completely Design (RCD). Treatment consists of three types of herbicides with six level of dosage active ingredient, namely of single herbicides is atrazin 500 g l-1 (0, 76, 152, 304, 608, and 1.215 ha g-1), mesotrion 50 g l-1 (0, 11, 22, 43, 86, and 172 g ha-1), and mixed herbicides from atrazin 500 g l-1 + mesotrion 50 g l-1 (0, 28, 56, 112, 225, and 450 g ha-1). The target weed were a type of broadleaves (Asystasia gangetica), a type of grasses (Paspalum conjugatum), and a type of sedges (Cyperus kyllingia).Homogenity tested using Bartlet and aditivity tested using Tukey, data analyzed by Analisis of Variance and different median values tested with Least Significant Difference (LSD) level 5%. Results showed that an active ingredient mixture of atrazin 500 g L-1 + mesotrion 50 g L-1 has LD50 expectation value of 51,48 g ha-1 and LD50 treatment of 257,48 g ha-1 with the co-toxicity value was 0.2 (co-toxicity < 1) until mixture was antagonist.

Abstract

Tujuan dilakukannya penelitian ini adalah untuk mengetahui efektivitas dari pencampuran herbisida dengan bahan aktif diuron dan hexazinon dalam mengendalikan gulma serta mengetahui sifat campuran kedua bahan aktif tersebut.  Penelitian ini dilakukan di rumah plastik Kecamatan Natar, Kabupaten Lampung Selatan dari bulan Mei hingga Juli 2022.  Penelitian disusun dalam Rancangan Acak Lengkap (RAL).  Perlakuan terdiri dari tiga jenis herbisida dengan enam tingkat dosis bahan aktif, yaitu herbisida tunggal diuron 80% WG (0, 0.25, 0.50, 1.00, 2.00, dan 4.00 kg ha-1), hexazinon 75% WG (0, 0.5, 1.0, 2.0, 4.0, and 8.0 kg ha-1), dan campuran herbisida dari diuron 46,8%  + hexazinon 13,2%  (0, 0.25, 0.50, 1.00, 2.00, and 4.00 kg ha-1).  Gulma sasaran meliputi dua jenis gulma golongan daun lebar (Ageratum conyzoides dan Asystasia gangetica), golongan rumput (Eleusine indica dan Paspalum conjugatum), serta golongan teki (Cyperus kyllingia dan Cyperus rotundus).  Herbisida diuron dan hexazinon memiliki cara kerja berbeda sehinggal metode analisis yang digunakan adalah metode Multiplicative Survival Model.  Hasil penelitian menunjukkan bahwa pencampuran herbisida diuron 46,8%  + hexazinon 13,2%  memiliki nilai LD50 harapan sebesar 69,29 g ha-1 dan LD50 perlakuan sebesar 55,77 g ha-1 dengan nilai ko-toksisitas sebesar 1,24 (ko-toksisitas > 1) sehingga campuran bersifat sinergis.

Abstract

The aim of this research was to know effectiveness and characteristic of mixing herbicide active ingredients atrazine, mesotrion, and nikosulfuron on several weed specieses. The trial conducted in the green house at South Lampung from December 2021 until February 2022. This Research arranged in a Randomized Completely Design. Treatment consists of four types of herbicides with six level of dosage active ingredient, namely of single herbicides is atrazin 200 g/l (0, 25, 50, 100, 200, and 400 g ha-1), nikosulfuron 20 g/l (0, 2.5, 5.0, 10, 20, and 40 g ha-1), mesotrion 40 g/l (0, 5, 10, 20, 40 and 80 g ha-1), and herbicides combination of atrazine, nikosulfuron, and mesotrion 200/20/40 OD (0, 32.5, 65, 130, 260, and 520 g ha-1). The target weed were 3 type of broadleaves weeds (Ageratum conyzoides, Euphorbia hirta, and Richardia brasiliensis), 3 type of grasses weeds (Digitaria ciliaris, Eleusine indica, and Rottboellia cochinchinensis), and sedges weed (Cyperus rotundus). Multiplicative Survival Model method used in this research because atrazin, nikosulfuron, and mesotrion have different mode of action. Results showed that an active ingredient mixture of atrazin 200 g/l, nikosulfuron 20 g/l, and mesotrion 40 g/l has LD50 expectation value of 155.96 g ha-1 and LD50 treatment of 74.27 g ha-1 with the co-toxicity value was 2.10 (co-toxicity >1), it means that the characteristic oh the herbiscides mixture  is synergist or not antagonist.
