Abstract

Desa Sukarame memerupakan bagian dari Kecamatan Leles, Kabupaten Garut. Desa ini berada di dataran medium (697 mdpl) dan memiliki luas wilayah yaitu 374,3 ha, yang terdiri dari tanah sawah 92 Ha, tanah kering 224 Ha dan tanah perkebunan 5 Ha. Jumlah penduduk Desa Sukarame sebanyak 6.169 jiwa dan mayoritas adalah sebagai buruh tani. Petani di Desa Sukarame umumnya bertanam tanaman padi sawah dan tanaman jagung sebagai tanaman utama. Pola tanam yang biasa dilakukan di Desa Sukarame adalah Padi-padi-jagung. Sistim tanam tanaman jagung adalah secara konvensional yaitu persiapan tanah, pencangkulan tanah dua kali kemudian penanaman. Sistim penanaman ini memerlukan tenaga kerja dan upah yang tinggi, sehingga pendapatan petani jadi berkurang. Sistim penanaman pada tanaman padi sawah dan tanaman jagung di Desa Sukarame adalah secara konvensional yaitu masih menggunakan pupuk anorganik. Penggunaan pupuk organic atau kompos belum banyak digunakan para petani di Desa Sukarame, walaupun bahan pembuatan pupuk organic seperti limbah rumah tangga, limbah pertanian dan peternakan banyak tersedia di wilayah Desa Sukarame. Penggunaan pupuk organic atau kompos selain bisa menyuburkan tanah dalam jangka panjang juga bisa mengurangi biaya produksi. Pembuatan pupuk organik yang berasal dari limbah pertanian, rumah tangga dan kotoran ternak ini belum banyak dikenal di Desa Sukarame. Pelatiahan yang telah dilaksanakan telah memiliki dampak sebagai berikut: (1) Pengetahuan dan ketrampilan petani khususnya peserta kegiatan bertambah dengan adanya penyuluhan dan pelatihan pembuatan pupuk organic atau kompos yang baik dan benar. (2) Masyarakat sasaran bertambah pengetahuannya tentang pentingnya menjaga kesuburan tanah dengan mengurangi penggunaan pupuk kimia. (3) Masyarakat tani tanggap dan termotivasi untuk mengurangi penggunaan pupuk kimia dan mulai menggunakan pupuk kompos, karena penggunaan pupuk kompos dalam jangka Panjang bisa menyuburkan tanah.

Abstract

Glyphosate is a non-selective systemic herbicide that has been widely used to control weeds by local corn farmers in South Sulawesi and Lampung Provinces of Indonesia. However, some corn farmers in these two regions were considered that glyphosate herbicide at the standard field dose no longer effective against goosegrass (Eleusine indica). To confirms the level of its resistance to glyphosate, seeds of E. indica suspected to be glyphosate-resistant were collected from corn fields in Soppeng Regency-South Sulawesi and South Lampung Regency-Lampung (designated as GR-1 and GR-2 respectively), along with a known susceptible biotype from Sumedang Regency-West Java (GS) as a comparison. By using whole-plant pot assay method in a greenhouse at the Ciparanje. A range of seven glyphosate concentrations was applied to the seedlings at the Experimental Farm, representing 0, 0.25, 0.5, 1, 2, 4, and 8 x the standard field rate. Dose–response experiment showed that GR-1 and GR-2 biotypes has a low levels resistance to glyphosate (2.57 and 2.96 folds of each) compared to susceptible biotype (GS). Sequencing results confirmed the Pro-106-Ser mutation in the EPSPS genes of the resistant biotypes. This specific amino acid substitution is among the most frequently documented mechanisms of resistance in weed species. Therefore, the shared mutation in the GR-1 and GR-2 biotypes likely confers this resistance. These findings serve as an early warning for corn farmers to manage and prevent further spread of E. indica glyphosate-resistant biotypes.

Abstract

Indonesian rice production has been unable to fully meet national demand, partly due to weed competition, which can reduce rice yields by up to 80% if left uncontrolled. This study aimed to evaluate the effectiveness of pre-emergence herbicides containing pretilachlor (300 g/L) and post-emergence herbicides containing cyhalofop + ethoxysulfuron (330 g/L) for weed control in direct-seeded rice, and  to determine the optimal dosage. Herbicides active ingredient is pretilachlor are a category of pre-emergence herbicides used in rice cultivation; these herbicides are systemic and are used to control sedges, grasses and broadleaf weeds. The cyhalofop + ethoxysulfuron herbicide is a post-emergence herbicide mixture that can suppress the growth of sedges, broad-leaved weeds and grasses . The study was conducted at PT. Syngenta Indonesia R&D Cikampek Site from August to December 2024, using a Randomized Group Design (RGD) with four replications and six treatments, namely two doses of pre-emergence herbicide (1.0 and 0.5 L/ha), two doses of post emergence herbicide (1.0 and 0.5 L/ha), manual weeding, and control (without treatment). The parameters observed included the weed vegetation analysis, dry weight of weeds, and the components of rice plant growth and yield. The results showed that pre-emergence herbicides with the active ingredient pretilachlor 300 g/L  and post-emergence herbicides with the active ingredient mixtures of cyhalofop + ethoxysulfuron 330 g/L  are effective in controlling various important weeds in the direct seeding system of rice cultivation, such as Cyperus iria, Echinochloa crus-galli, Fimbristylis miliacea, and Leptochloa chinensis, thus helping rice plants grow optimally and increasing yields. Pre-emergence herbicide with the active ingredient pretilachlor 300 g/L  at a dose of 1.0  L/ha gave the best results in suppressing weed growth and increasing rice yields compared to other treatments.
