Benzylpyrimidine·Propachlor 35% Wettable Powder
Bensulfuron-methyl + Pretilachlor 35% WP
Pesticide Category: Herbicides Dosage form: Wettable Powder (WP) | Toxicity: lower toxicity
Active ingredients: Benzylsulfuron + Propachlor | Total active ingredient content: 35%
Active ingredients: Benzylsulfuron + Propachlor | Total active ingredient content: 35%
I. Product Profile
Benzylpyrimidine·Propachlor 35% Wettable Powder is aBinary Formulation Herbicide Specifically Designed for Rice Fields, bySulfonylurea-based broadleaf sedge herbicide (benzothiadiazole)andAmide-type mitosis inhibitors (propachlor)Scientifically formulated. This product combines the dual effects of ”seal-in and systemic action” and provides excellent control of annual weeds in direct-seeded rice fields, making it a highly effective solution for integrated weed management in 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 | Cell division inhibitor, interfering with the synthesis of very-long-chain fatty acids | Pre-sprout soil treatment; absorption by young sprouts |
The Principle of Synergy
-
Broadleaf Cyperus Herbicide (Benzylsulfuron): It selectively inhibits the biosynthesis of the essential amino acids valine and isoleucine in organisms, thereby preventing cell division and halting plant growth. It is a systemic herbicide; the active ingredient is absorbed by the leaves and roots and moves rapidly through the meristematic tissues. It is highly effective against duckweed, water caltrop, water parsnip, and other weeds, as well as Cyperaceae weeds.
-
Grass Weed Control (Propachlor): It is rapidly absorbed by embryos and the roots of germinating weeds and acts as a cell division inhibitor. Since weed seeds absorb the herbicide during germination but root absorption is poor, it can only be used as a pre-emergence soil treatment.
-
Synergy: Benzylsulfuron compensates for propachlor’s poor efficacy against broadleaf weeds and Cyperaceae weeds; propachlor compensates for benzylsulfuron’s poor efficacy against barnyard grass, thereby achieving complete control of grass, broadleaf, and Cyperaceae weeds in rice fields.
III. Product characteristics
✅ Six Core Advantages
forms
| Specificities | particular |
|---|---|
| 🎯 Completely eliminates He Kuosha; broad-spectrum and highly effective | It provides excellent control of annual grassy weeds, broadleaf weeds, and sedge weeds in rice fields. |
| 🔄 Enclosed and systemic—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 direct-seeded rice fields at the recommended dosage and does not affect tillering or yield. |
| 💧 Flexible and versatile | Can be applied as a soil spray; suitable for direct-seeding rice cultivation |
| 🌾 Specially formulated for consistent results | Designed specifically for direct-seeding rice fields, with results proven over many years |
🎯 Preventing Objects
Primary prevention and eradication: Annual weeds such as barnyard grass, golden-seed grass, duck’s-tongue grass, water milfoil, jointed waterweed, cowhair rush, odd-leaved sedge, broken-grain sedge, water sedge, and water-snake grass.
Suitable crops: Direct-seeded rice fields.
IV. Usage and dosage
📋 Implementation Plan for Direct-Seeded Rice Fields
forms
| Application period | Dosage (formulated dose/acre) | water consumption | Mode of application |
|---|---|---|---|
| 2–4 days after rice sowing | 60–80 grams per mu | 30-40 kg/mu | Soil spraying |
Active ingredient dosage: The application rate of the active ingredient per mu is 21–28 grams per mu. Maintain a shallow layer of water 3–5 centimeters deep in the field when applying the pesticide.
V. Guidance for use
🔧 Application Points
forms
| move | operational specification |
|---|---|
| 1. Seize the opportunity | Apply the herbicide 2–4 days after rice seeding; it is most effective during the early stages of weed emergence. |
| 2. Aquifer management | When applying the pesticide, maintain a shallow layer of water 3–5 centimeters deep in the field for 3–5 days, then allow it to dry out naturally. |
| 3. Dispensing methods | Use the two-step dilution method to ensure that the chemical is thoroughly dispersed. |
| 4. Spray evenly | Mix 30–40 kilograms of the product per mu with water and spray it evenly onto the soil; do not allow water to pool on the ridges. |
⚠️ Key Considerations
-
⏰ Optimal application period: After Rice Seeding2–4 daysThis provides the best results.
-
💧 Water Management: Maintain the following conditions in the field during application:Shallow water layer, 3–5 centimeters, leave it for 3–5 days to let it dry naturally,Water must not pool on the ridges., and manage it as usual going forward.
-
🌧️ Weather Taboos: Do not apply pesticides on days with strong winds or when rain is expected within the next hour.
-
🚫 Prohibited plots: Use with caution in fields with young seedlings, sandy soils, or fields with poor drainage.
-
🐟 Aquatic safety: This product is toxic to fish and other aquatic organisms; keep it away from water bodies such as rivers and ponds when applying it, and do not wash application equipment in rivers, ponds, or other bodies of water. It is also toxic to Trichogramma wasps; do not use this product in areas where Trichogramma wasps have been released.
-
🧪 Mixing Taboo: Do not mix with alkaline substances such as pesticides.
-
🔄 Number of uses: This product should be used no more than1 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 harming aquatic life.
-
📦 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.
