Description
Ben·Eth 14% Wettable Powder
Bensulfuron-methyl + Acetochlor 14% WP
Active ingredients: Benzylsulfuron + Acetochlor | Total active ingredient content: 14%
I. Product Profile
Ben·Yi 14% Wettable Powder is aBinary Formulation Herbicide Specifically Designed for Rice Fields, bySulfonylurea-based broadleaf sedge herbicide (benzothiadiazole)andAmide-based grass weed pre-emergence herbicide (acetochlor)Scientifically formulated. This product combines the dual effects of ”surface-acting and systemic” action, providing excellent control of annual monocotyledonous, dicotyledonous, and Cyperaceae weeds in rice fields. It is a classic product for the comprehensive management of weeds in transplanted rice fields.
II. Mechanisms of action of active ingredients
Mechanism of dual-target synergy
forms
| Ingredients | Function Category | mechanism of action | Mechanism of action |
|---|---|---|---|
| Bensulfuron | HRAC Class B / WSSA Class 2 | Acetyl-L-lactate synthase (ALS) inhibitors, inhibiting the synthesis of branched-chain amino acids | Systemic, absorbed by roots and leaves |
| also called dimethoate | HRAC Category K3 / WSSA Category 15 | Inhibitors of very-long-chain fatty acid (VLCFA) synthesis, interfering with cell membrane formation | Pre-sprout soil treatment; absorption by young sprouts |
The Principle of Synergy
-
Broadleaf Cyperus Herbicide (Benzylsulfuron): Once absorbed by the roots and leaves of weeds, it is transported to various parts of the plant, inhibiting the biosynthesis of branched-chain amino acids and preventing cell division and growth. It is highly effective against duckweed, water caltrop, water parsnip, heteromorphic sedge, rice-grain sedge, and cowhair moss.
-
Grass Weed Control (Acetochlor): It is absorbed through the young shoots of weeds, inhibits VLCFA synthesis, and blocks cell membrane formation, preventing weeds from emerging or causing them to die after emergence. It is highly effective against grass weeds such as barnyard grass and foxtail.
-
Synergy: Benzylsulfuron compensates for the poor efficacy of acetochlor against broadleaf weeds and Cyperaceae weeds; acetochlor compensates for benzylsulfuron’s poor efficacy against barnyard grass, thereby achieving complete control of rice, broadleaf weeds, and Cyperaceae weeds in rice fields.

| 🔄 Systemic protection and sealing—double protection | It combines the dual effects of soil-applied and systemic action, providing control against both emerged and pre-emerged weeds. |
| ⏱️ Long-lasting, one application lasts | A Single Application of Pesticide Effectively Controls Weed Damage During the Seedling Stage of Rice |
| 🛡️ Safe for rice, highly selective | It is safe for rice at the recommended dosage and does not affect tillering or yield. |
| 💧 Flexible and versatile | Can be broadcast-applied as a soil treatment or mixed with fertilizer and broadcast-applied; suitable for transplanted field cultivation systems |
| 🌾 Classic formula, consistent results | The benzoyl-ethyl mixture is a classic weed control formulation for rice fields, and its effectiveness has been proven over many years. |
🎯 Preventing Objects
Primary prevention and eradication: Barnyard grass, thousand-gold seed, melon-rind grass, water dragon, heteromorphic sedge, broken-grain sedge, cowhair felt, duck’s-beak grass, rain-long flower, jointed water-celery, snake’s-intestine, field-mustard, clove smartweed, water amaranth, water-milfoil, water plantain, motherwort, and other annual monocotyledonous weeds, dicotyledonous weeds, and Cyperaceae weeds.
IV. Usage and dosage
📋 Rice field use program
forms
| Crop type | Application period | Dosage (formulated dose/acre) | Water Body Management | Mode of application |
|---|---|---|---|---|
| Rice transplanting field | 4–7 days after transplanting | 100–120 grams per mu | Maintain a 3-centimeter water layer before application, and keep the soil moist for 4–7 days after application. | The "medicated soil" method or spreading a mixture with urea |
Active ingredient dosage: The application rate of the active ingredient per mu is benzosulfuron 2–2.4 grams per mu + Acetochlor 12–14.4 grams per mu。
V. Guidance for use
🔧 Application Points
forms
| move | operational specification |
|---|---|
| 1. Seize the opportunity | Apply the herbicide 4–7 days after rice transplanting, when the seedlings have become established but weeds have not yet emerged in large numbers. |
| 2. Field Preparation | Keep the field level and maintain a shallow layer of water |
| 3. Aquifer Management | Maintain a water depth of 3 cm in the field during application, and keep the field moist for 4–7 days after application. |
| 4. Preparation of Medicinal Soil | Mix the formulation with 7.5 kilograms of urea or 20 kilograms of fine soil per mu, and apply evenly after the dew has dried. |
| 5. Apply the pesticide evenly | Ensure that the pesticide is evenly distributed over the field to avoid over-spraying or missed spots. |
⚠️ Key Considerations
-
⏰ Optimal application period: After rice transplanting4–7 daysThis is the optimal time for application; applying too early may cause phytotoxicity, while applying too late, when weeds have already emerged, will reduce the effectiveness of the pre-emergence treatment.
-
🚫 Contraindications: This type of medication is used inUnder low-temperature conditions, young seedlings and weak seedlings are prone to growth inhibition.; It poses no risk to late-season rice in the Yangtze River Basin or transplanted rice fields in the southwestern provinces.
-
💧 Water Management: When applying pesticides, rice fields should be kept3 cm of shallow water, The water depth should not exceed the height of the rice plant’s central leaf; maintain water levels after application.4–7 days, the water supply must not be interrupted.
-
🌡️ Temperature effects: Low temperatures can inhibit the growth of young seedlings and weak seedlings; therefore, avoid applying pesticides during periods of low temperatures.
-
🐟 Aquatic safety: Apply pesticides away from aquaculture areas; do not wash application equipment in water bodies.
-
🧪 Mixing Taboo: Do not mix with alkaline pesticides; it is recommended to rotate this product with herbicides that have different modes of action.
-
🔄 Number of uses: Maximum use per growing season1 time。
-
🛡️ security: Wear protective clothing, gloves, and a mask when applying the pesticide; wash your hands and face immediately after application; pregnant and breastfeeding women should avoid contact.
-
🧹 Instrument cleaning: Thoroughly clean the sprayer after use to prevent residual pesticide from causing phytotoxicity to other crops.
-
📦 Storage conditions: Store in a cool, dry, well-ventilated place, away from direct sunlight and high temperatures; keep away from sources of fire and out of the reach of children.
