FARMCOCHEM BUFOS 135 

🔹 Kategori: Racun Rumpai (Herbicide)
🔹 Kumpulan MOA: Phosphinic acid – HRAC Group 10 (Perencat glutamine synthetase)
🔹 Bahan Aktif: Glufosinate-ammonium 13.5% w/w
 

Cara Tindakan

• Bertindak secara sentuhan dengan sedikit pergerakan sistemik.

• Menghalang penukaran glutamat → glutamin, menyebabkan ammonia terkumpul → fotosintesis terhenti → daun menjadi kering.

• Tidak selektif, sesuai untuk kawalan rumpai spektrum luas.

Jenis Kawalan

✅ Rumpai daun lebar tahunan & saka
✅ Rumput-rumput
✅ Jenis teki (sedges)

👉 Alternatif kepada paraquat atau glyphosate untuk ladang, kebun buah & kawasan industri.

Gejala Selepas Semburan

• 1–2 hari: Daun mula klorosis (menguning)

• 3–5 hari: Nekrosis (daun mati)

• 7–14 hari: Rumpai mati sepenuhnya jika rumpai sedang aktif tumbuh

• Kalis hujan: ± 4 jam selepas semburan

Kadar Penggunaan (Semburan Darat)

📌 Ujian ladang di Malaysia: 600 g a.i./ha (~4.4L Bufos 135) dalam 200L air → >95% kawalan rumpai campuran di sawit muda.

Cara Bancuhan & Semburan

1. Isikan separuh tangki dengan air bersih, hidupkan pengacau.

2. Masukkan Bufos 135 sambil kacau.

3. Tambah air hingga cukup isipadu.

4. Jika air keras (>200 ppm), tambah surfaktan bukan ionik 0.1%.

5. Sembur sehingga daun basah sekata (tidak menitis).

6. Gunakan muncung flat-fan/deflector, tekanan 200–300 kPa.

7. Elak hanyutan; jangan sembur jika angin >10 km/j atau hujan dijangka <4 jam.

Keselamatan & Alam Sekitar

• Sesuai untuk semburan terarah di bawah sawit, getah, koko, durian, buah-buahan, kawasan industri & burndown pra-tanam.

• Masuk semula selepas semburan kering (~12 jam).

• Separuh hayat tanah (DT₅₀): ± 3–10 hari → residu sangat minima.

• WHO Class III (Berhati-hati).

• PPE wajib: sarung tangan, baju perlindungan, pelindung muka. Bekas kosong perlu dibilas 3 kali & dipatahkan sebelum lupus.

FARMCOCHEM BUFOS 135 

🔹 Category: Herbicide
🔹 MOA Group: Phosphinic acid – HRAC Group 10 (Glutamine synthetase inhibitor)
🔹 Active Ingredient: Glufosinate-ammonium 13.5% w/w
 

Mode of Action

• Contact herbicide with limited systemic movement.

• Inhibits conversion of glutamate → glutamine → ammonia accumulation → photosynthesis collapse → rapid foliage desiccation.

• Non-selective, effective for broad-spectrum weed control.

Target Weeds

✅ Annual & perennial broadleaf weeds
✅ Grasses
✅ Sedges

👉 Alternative to paraquat or glyphosate in plantations, orchards, and industrial sites.

Visible Symptoms

• 1–2 days: Leaf chlorosis

• 3–5 days: Tissue necrosis

• 7–14 days: Complete kill when weeds are actively growing

• Rainfast: ~4 hours

Recommended Field Rates (Ground Spray)

📌 Malaysian trials: 600 g a.i./ha (~4.4L Bufos 135) in 200L water gave >95% weed control in young oil palm.

Mixing & Spraying

1. Half-fill spray tank with clean water, start agitation.

2. Add Bufos 135 while stirring.

3. Top up to required volume.

4. If water hardness >200 ppm, add 0.1% non-ionic surfactant.

5. Spray to full leaf coverage (not run-off).

6. Use flat-fan or deflector nozzles at 200–300 kPa.

7. Avoid drift; do not spray if wind >10 km/h or rain expected <4 h.

Crop & Environmental Safety

• Directed/shielded sprays under oil palm, rubber, cocoa, fruit trees, industrial areas, pre-plant burndown.

• Safe re-entry once deposits dry (~12 h).

• Very short soil persistence (DT₅₀ 3–10 days), minimal residues in Malaysian conditions.

• WHO Class III (Caution).

• PPE required: gloves, protective clothing, face shield. Triple rinse & puncture empty containers before disposal.
