Product Overview

Cyhalofop-butyl 50g/L + Penoxsulam 10g/L OD is a selective post-emergence rice herbicide combining ACCase and ALS inhibitor pathways. Formulated as an oil dispersion (OD), it controls resistant barnyardgrass, sprangletop, sedges, and annual broadleaf weeds in direct-seeded and transplanted rice systems.

Process Engineering & Formulation Advantages

Methylated Seed Oil (MSO) Matrix: Prevents gravitational settling, phase separation, and hard-caking during multi-week maritime transit under shifting tropical temperatures.
Sub-Micron Shear Milling: Ensures 92% of active ingredient crystal particles are sized under 2.5 micrometers. Maximizes foliar coverage and provides rainfastness within 1 hour.
Integrated Surfactant Package: Polymeric ethoxylated surfactants reduce aqueous surface tension, eliminating the need for external tank adjuvants or crop oils.

Commercial Customization & Private Label Options

Engineered Packaging Formats:
Retail Sizes: 100mL, 250mL, 500mL, 1L bottles.
Structure: Multi-layered co-extruded (COEX) or barrier HDPE bottles with reinforced vertical ribs to prevent vacuum-collapsing and oil-seepage.
Chemical-Shield Booklet Labels: Multi-page peel-and-read labels finished with a solvent-resistant UV coating to accommodate multi-crop rate tables without text fading.
Localization Typesetting: Compliance translation and layout support for English, Spanish, French, Portuguese, Arabic, and Russian target markets.

Targeted Rice Field Applications

Target Rice Systems	Primary Target Weeds	Recommended Application Timing & Technical Keys
Direct-Seeded Rice (DSR)	Barnyardgrass, Sprangletop, Cyperus Sedges	Apply post-emergence at the 2 to 4 leaf stage of rice. Drain the field before application to expose 70% of weed foliage, re-flood 24-48 hours later.
Transplanted Rice	Monochoria, Arrowhead, Annual Sedges	Apply 10 to 15 days after transplanting during early active weed growth. Maintain a shallow water layer (3 to 5 cm) post-application.

FAQ

Q: How does your manufacturing process address phase separation and sediment caking common to OD formulations?

A: We pass the oil dispersion through a high-shear emulsification loop combined with a multi-layered organoclays thickener matrix. This creates a yield stress network that locks active particles in place. Any minor oil separation after long-term storage is standard top-layer syneresis (under 2%), which completely redisperses into a homogeneous liquid with a brief shake.

Q: What moisture control threshold do you maintain to prevent the hydrolysis of Cyhalofop-butyl?

A: Cyhalofop-butyl undergoes rapid degradation in the presence of water. We enforce a strict moisture cap of 0.4% Max across raw materials and carrier oils using Karl Fischer titration (CIPAC MT 30.5). Dehydrated stabilizers are incorporated during compounding, limiting active ingredient degradation to under 2.0% during 14-day heat storage testing at 54C.

Q: Does this premix control advanced-stage Barnyardgrass (Echinochloa spp.) resistant to ALS inhibitors?

A: Yes. The dual mode-of-action formulation targets separate pathways to manage resistance. While Penoxsulam controls standard sedges and broadleaf weeds via ALS inhibition, Cyhalofop-butyl targets the ACCase enzyme pathway, ensuring reliable control of advanced 3-to-4 leaf stage barnyardgrass that survives single-active ALS treatments.

Q: Will this OD formulation cause nozzle clogging when diluted in high-mineral hard water?

A: No. The product features an integrated non-ionic ethoxylated surfactant package. Tested under CIPAC MT 180 guidelines in standard hard water up to 342 ppm, it forms a uniform emulsion with a 45-micrometer wet sieve passing rate of 99.2% Min, ensuring zero filter blockage or nozzle failures.

Q: What technical documentation do you provide to support local import registrations?

A: We provide batch Certificates of Analysis (COA), GHS-compliant Safety Data Sheets (SDS), and Technical Data Sheets (TDS) within 3 business days of contract finalization. For long-term distribution partners requiring multi-batch impurity profiles or verified manufacturing process flowcharts, please contact our international trade team to arrange data-sharing terms.

Q: Why are COEX or barrier bottles required for this formulation instead of standard HDPE?

A: Methylated vegetable oils and surfactants can slowly migrate through standard high-density polyethylene (HDPE) walls over time. This causes container paneing, structural collapsing, or oil-seepage under hot warehouse conditions. We exclusively use multi-layered co-extruded (COEX) or internally treated barrier bottles to prevent chemical migration and maintain packaging integrity.

Q: What are your minimum order quantities (MOQ) for custom branding, and do you permit independent pre-shipment inspections?

A: Our standard MOQ for customized private labeling is 3,000 Liters for small retail packs (1L and below) and 5,000 Liters for bulk pack configurations. We fully welcome pre-shipment inspections (PSI) at our logistics facility by independent testing bodies like SGS, Bureau Veritas, or Intertek to verify active ingredient levels via HPLC and seal integrity before container loading.
