I. Product Profile

Pentafluorosulfuron 5% Dispersible Oil Suspension is aA New, Highly Effective, Selective Herbicide for Rice Fields, which belongs to the triazole-pyrimidine sulfonamide class of herbicides. This product hasBroad-spectrum weed control, extremely high activity, and good safety for riceWith these characteristics, it effectively controls barnyard grass, sedge weeds, and broadleaf weeds in rice fields, and is also effective againstMature Barnyard GrassIt remains highly effective and is the product of choice for integrated weed management in rice fields.

II. Mechanisms of action of active ingredients

Target: Acetyl-L-lactate synthase (ALS) inhibitor

Pentafluorosulfuron belongs toHRAC Class B / WSSA Class 2Herbicides with a mechanism of action:

forms

active link	Specific mechanisms
absorption pathway	Mainly throughFoliar Uptake by Weeds, and secondly, throughRoot Absorption, conducted through the phloem and xylem
biochemical target	Inhibiting the activity of acetyl-L-lactate synthase (ALS), inhibiting the synthesis of branched-chain amino acids
physiological effect	Inhibits the biosynthesis of valine, leucine, and isoleucine, and prevents cell division
final performance	Sensitive weeds rapidly stop growing after being treated with the herbicide and gradually turn yellow and die.

Characteristics of action

High conductivity: It is transported bidirectionally through the phloem and xylem within the plant and accumulates at the meristem.
Comprehensive Guide to Weed Control: Highly effective against barnyard grass, sedges, broadleaf weeds, and aquatic weeds
Effective against mature weeds: It remains effective against older barnyard grass at the 3–5-leaf stage, and the application window is broad.
Low toxicity and environmentally friendly: Safe for non-target organisms; environmentally friendly

III. Product characteristics

✅ Six Core Advantages

forms

Specificities	particular
🎯 Broad-spectrum weed control; one product, multiple uses	Highly effective against barnyard grass, sedges, broadleaf weeds, and aquatic weeds; controls the major weeds in paddy fields
🔄 Works for older singles	It remains highly effective against older barnyard grass at the 3–5-leaf stage, with a wide application window and high tolerance for application errors.
⏱️ Extremely active, requires only a very small amount	Excellent pest control can be achieved with extremely low doses of the active ingredient, making it both economical and environmentally friendly.
🛡️ Safe for rice, highly selective	Safe for rice growth; does not affect tillering or yield
💧 Dispersible oil suspension for enhanced efficacy	The OD formulation offers good dispersibility, strong adhesion, resistance to rain wash-off, and more stable efficacy.
🌾 Versatile and adaptable	Can be applied as a spray or as a soil treatment; suitable for various cultivation methods

🎯 Preventing Objects

Primary prevention and eradication: Barnyard grass (including mature barnyard grass), heteromorphic sedge, water plantain, field mustard, duckweed, jointed waterweed, water amaranth, clove smartweed, water caltrop, duckweed, and water hyssop, as well as other annual and some perennial weeds.

Suitable crops: Rice transplanted fields, direct-seeded rice fields, and rice fields with scattered seedlings.

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	5–7 days after transplanting	30–60 milliliters per mu	30-50kg/mu	Spraying or applying toxic soil
Rice direct seeding field	When seedlings have 2–3 leaves	30–60 milliliters per mu	30-50kg/mu	Spraying or applying toxic soil
Rice Fields with Transplanted Seedlings	5–7 days after transplanting	30–60 milliliters per mu	30-50kg/mu	Spraying or applying toxic soil

Active ingredient dosage: The recommended application rate of the active ingredient in the field is 15–45 grams per hectare(Approx. 1–3 grams per mu).

V. Guidance for use

🔧 Application Points

forms

move	operational specification
1. Field preparation	Level the field and maintain a shallow layer of water (3–5 centimeters).
2. Aquifer management	Maintain a water depth of 3–5 centimeters during application, and keep the water in the field for 5–7 days after application.
3. Dispensing methods	Use the two-step dilution method to ensure uniform dispersion.
4. Spray Quality	Apply evenly, avoiding overlapping or missed areas.
5. The Poisonous Soil Method	Mix the formulation with 20–30 kilograms of fine soil per mu, and apply it evenly after the dew has dried.

⚠️ Key Considerations

⏰ Grasp the application window: Apply the herbicide 5–7 days after transplanting in transplanted fields; in direct-seeded fields, apply the herbicide when the seedlings have 2–3 leaves; the best results are achieved when weeds have 2–4 leaves.
💧 Water Management: When applying the pesticide, make sure to3-5 cm shallow water layerPost-application water retention5-7 days, Do not drain the field or cross-irrigate during this period, and ensure that the water level does not submerge the rice plants’ young leaves.
🌡️ Temperature effects: The product takes effect more quickly at higher temperatures; at lower temperatures, it takes effect more slowly, but this does not affect its ultimate efficacy.
🚫 Contraindications: Use with caution during the rice seedling stage (before the “standing needle” stage) to avoid phytotoxicity; efficacy may be reduced in waterlogged fields or sandy soils.
🐟 Aquatic safety: Apply the pesticide away from aquaculture areas; do not wash application equipment in water bodies such as rivers or ponds.
🧪 Mixing Taboo: Do not mix with alkaline pesticides; it is recommended to rotate this product with herbicides that have different modes of action.
🔄 Resistance management: Long-term single use is prone to resistance, it is recommended to combine withCyanofluoroxazol, Oxazolyl-2-chlorophenoxyacetic acidRotate the use of herbicides with different modes of action, applying them no more than 1–2 times 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 pesticide residue from causing phytotoxicity to subsequent crops.
📦 Storage conditions: Store in a cool, dry place, away from direct sunlight and high temperatures; shake the OD formulation well before use.
