Benzyl Dichloride 35% Wettable Powder

Bensulfuron-methyl + Quinclorac 35% WP

Pesticide Category: Herbicides Dosage form: Wettable Powder (WP) | Toxicity: lower toxicity
Active ingredients: Benzylsulfuron + Dichloroquinoline Acid | Total active ingredient content: 35%

I. Product Profile

Benzyl Dichloride 35% Wettable Powder is aBinary Formulation Herbicide Specifically Designed for Rice Fields, bySulfonylurea-based broadleaf sedge herbicide (benzothiadiazole)andQuinoline carboxylic acid-based weed herbicide (dichloroquinoline carboxylic acid)Scientifically formulated. This product offers dual efficacy against ”barnyard grass and broadleaf and sedge weeds,” providing excellent control over the major weed types found in rice fields—barnyard grass, broadleaf weeds, and sedge weeds—all major weed types in rice fields. A single application can effectively control weed damage in rice fields, making it a highly efficient 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
dichloroquinolinic acid	HRAC Class O / WSSA Class 19	Synthetic hormone inhibitors, disrupting auxin metabolism	Systemic; absorbed by roots and leaves and transported upward

The Principle of Synergy

Broadleaf Cyperus Herbicide (Benzylsulfuron): The active ingredient rapidly disperses in water; after being absorbed by the roots and leaves of weeds, it is transported throughout the plant, inhibiting the biosynthesis of branched-chain amino acids (such as isoleucine) and blocking cell division and growth, thereby stunting the weeds and causing them to die. It is highly effective against duckweed, water caltrop, water parsnip, and other weeds, as well as Cyperaceae weeds.
Weed Killer (Dichloroquinoline Acid): It is rapidly absorbed by the seeds, roots, and leaves of emerging weeds, primarily through the roots. After absorption, it is transported within the plant to the apical meristems and stems, where it primarily inhibits the growth points of barnyard grass, ultimately causing the leaves to droop, wilt, and die. It is highly effective against barnyard grass (Oryza sativa) and common barnyard grass (Echinochloa crus-galli) in the 1–7-leaf stage.
Synergy: Benzylsulfuron compensates for dichloroquinoline acid’s poor efficacy against broadleaf weeds and sedge weeds; Dichloroquinoline acid compensates for benzosulfuron’s poor efficacy against barnyard grass, thereby achieving complete control of grass, broadleaf, and sedge weeds in rice fields.

III. Product characteristics

✅ Six Core Advantages

forms

Specificities	particular
🎯 Hekuosha: Total Control—One Product, Multiple Effects	Simultaneously controls barnyard grass, broadleaf weeds, and sedge weeds, covering the major weeds found in rice fields
🔄 Systemic action, thoroughly eradicates	Both active ingredients are systemic, destroying weeds from within and preventing regrowth.
⏱️ Wide application window, high tolerance for errors	The herbicide can be applied 5–20 days after transplanting in transplanted fields; it is effective against barnyard grass at all stages from 1 to 7 leaves.
🛡️ 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 sprayed or mixed with soil and broadcast; suitable for various cultivation methods, including transplanting and rice paddy cultivation.
🌾 One application, protection for the entire season	A single application of herbicide can effectively control weeds in rice fields

🎯 Preventing Objects

Primary prevention and eradication: Barnyard grass (1–7-leaf stage), duckweed, water celery, bitterweed, water-lily, water-melon vine, rainflower, field bindweed, soapberry, heteromorphic sedge, broken-grain sedge, and cowhair sedge, among other annual and some perennial weeds.

Suitable crops: Rice transplanting fields and rice seedling beds.

IV. Usage and dosage

📋 Rice field use program

forms

Crop type	Application period	Dosage (formulated dose/acre)	water consumption	Mode of application
Rice transplanting field	5–20 days after transplanting, when barnyard grass is in the 2–3-leaf stage, is the optimal time.	40–50 grams per mu	30-40 kg/mu	Foliar spray
rice paddy	After the 3-leaf stage of rice seedlings; at the 2–3-leaf stage of barnyard grass	40–50 grams per mu	30-40 kg/mu	Foliar spray

Active ingredient dosage: The application rate of active ingredient per mu for 35% (benzyl·dichlor) is 14–17.5 grams per mu. Drain the field the night before application to ensure that the stems and leaves of the barnyard grass come into contact with the herbicide; irrigate the field one day after application and maintain moisture for 5–7 days.

V. Guidance for use

🔧 Application Points

forms

move	operational specification
1. Determine the age of the grass	The optimal time to apply the herbicide is when the barnyard grass has 2–3 leaves, though it can be applied at any stage from 1 to 7 leaves.
2. Drainage and Application of Pesticides	Drain the field the night before application to ensure that the stems and leaves of barnyard grass come into contact with the herbicide.
3. Spray evenly	Mix 30–40 kilograms of the product per mu with water and spray evenly to ensure complete coverage of the weeds.
4. Watering and Moisture Retention	Water the plants 1 day after application and maintain a water depth of 3–5 centimeters for 5–7 days.

⚠️ Key Considerations

⏰ Optimal application period: In transplanted fields, after rice seedlings have been planted5–20 daysPesticides can be applied in both cases, targeting barnyard grass2–3-leaf stageIt is best to apply the pesticide.
🚫 Pesticide damage to subsequent crops: High residue levels in the soil can easily cause phytotoxicity in subsequent crops; subsequent crops may include rice, corn, and sorghum, butSolanaceae (tobacco, potatoes, chili peppers, etc.), Apiaceae (carrots, celery), Amaranthaceae (spinach, sugar beet), Malvaceae, Cucurbitaceae (various melons and gourds), Fabaceae, Asteraceae, and Convolvulaceae crops are sensitive to this herbicide.。
💧 Water Management: Drain the water the day before application and apply a uniform spray. Irrigate one day after application and maintain a water depth of 3–5 centimeters for 5–7 days.
🌡️ Drift Risk: These crops (carrots, celery, cilantro, etc.) are quite sensitive to the Umbelliferae family; spray drift can easily cause phytotoxicity to these crops in adjacent fields, so spray drift should be avoided during application.
🐟 Aquatic safety: This product is non-toxic to fish and bees, but apply it away from aquaculture areas; do not wash application equipment in water bodies.
🧪 Blending recommendations: can be used withChlorimuron, Benfluralin, Pyrimethanil, Diquat, Cyhalothrin...are used in combination to broaden the spectrum of weeds controlled.
🔄 Resistance management: In some areas, dichlorquinoleic acid is frequently applied in excess, leading to cumulative herbicide damage in fields; it is recommended to rotate its use with herbicides that have different modes of action, and to apply it no more than once per season.
🛡️ 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 subsequent sensitive 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.
