Red Sun Cypermethrin Insecticide is a yellow-brown to dark reddish-brown viscous liquid or semi-solid. It has a refractive index of n25D 1.5650, vapor pressure of 5.066×10⁻⁶ Pa at 70℃ and 190×10⁻⁹ Pa (extrapolated to 20℃), with a relative density of about 1.2350 at 25℃. At 20℃, its solubility is: acetone >450 g/L, ethanol 337 g/L, xylene >450 g/L, chloroform >450 g/L, and hexane 103 g/L; in water, solubility is 0.01–0.2 mg/L at 21℃. The technical material is thermally stable below 220℃, relatively stable under acidic and field light conditions, but unstable in alkaline environments.

Cypermethrin is a broad-spectrum pyrethroid insecticide that targets sodium channels in insect nerve cells, disrupting signal transmission and causing paralysis and death, making it effective for agricultural pest control.
The insecticide acts through contact and stomach ingestion without systemic translocation in plants, and its performance depends on crop surface coverage, with sunlight and temperature influencing activity under field conditions.
Insects show rapid knockdown and paralysis within hours, with mortality occurring within 24–48 hours, and it provides reliable control of chewing and sucking pests across cereals, cotton, vegetables, and other major crop groups.
Field trials demonstrate more than 90% effective pest control at 25–50 g ai/ha, with visible results within 24 hours, and stable crop protection achieved under spray volumes of 200–400 L/ha at a pH of 5–6.
As a pyrethroid compound, Cypermethrin can be rotated or mixed with organophosphates, carbamates, or neonicotinoids to extend resistance management strategies, and resistant insect populations remain limited in agricultural fields.
The insecticide binds strongly to soil and organic matter, degrades quickly with a half-life of less than one day, shows no root uptake or leaching, and leaves minimal residues, ensuring safe harvest intervals in crop production.
Red Sun Cypermethrin Insecticide provides proven field efficiency, low residue risk, broad application flexibility, formulation compatibility, and reliable supply assurance. The following features highlight its competitive value for agricultural and municipal markets.
Cypermethrin delivers rapid insect control after application. Field data show pest activity declines within 2–4 hours, with over 95% leaf damage recorded within 24 hours. This quick action helps farmers reduce crop losses and improve application efficiency across large fields.
Once applied, Cypermethrin binds tightly to soil and organic matter. It shows a degradation half-life (DT₅₀) of less than one day. The compound does not leach or persist, making it compatible with crop rotation schedules and reducing risks of soil residue accumulation.
The product is registered for use in multiple environments. It is suited for agricultural pest control across cereals, cotton, and vegetables, and can also be applied in municipal settings where rapid action is required. Its versatility supports a wider market reach.
Cypermethrin is available in SL and AS formulations. It can be tank mixed with other insecticides such as organophosphates or neonicotinoids. This compatibility allows users to manage resistance more effectively while maintaining consistent control across diverse pest populations.
Red Sun operates multiple production facilities with ISO and ESG certifications. Annual output capacity ensures stable availability. With established logistics and multi-site manufacturing, customers benefit from consistent delivery and reduced risk of supply interruptions.
Compared with similar products, Cypermethrin offers measurable savings. Benchmark data show a 15–20% reduction in active ingredient costs compared with some competing insecticides. This cost structure supports competitive procurement and enhances long-term customer value.
Cypermethrin Insecticide from Red Sun is designed for crop protection and pest management across agricultural and industrial fields. The following points outline recommended use conditions and operational guidance.
Recommended rates are 25–50 g ai/ha or 0.2–0.4 g/L. Spray volumes range from 200–400 L/ha. Flat-fan nozzles are preferred, operated under 2–3 bar pressure for uniform coverage.
Best performance occurs when pests are at early growth stages. Temperature, sunlight, and leaf surface moisture influence activity. Applications under moderate conditions improve control reliability and consistency.
Cypermethrin can be tank mixed with glyphosate or glufosinate. Add Cypermethrin last in the mixing order. Buffering agents or wetting agents may be used when water hardness or coverage is an issue.
Minimum pre-harvest interval is 14 days. Re-entry interval (REI) is 24 hours. Drift reduction is supported by low-pressure settings and proper nozzle calibration to limit off-target impact.
Application follows national residue regulations and worker safety guidelines. Buffer zones and label instructions define operational boundaries. Compliance with these standards ensures professional use and safe integration into field SOPs.
Cypermethrin is a broad-spectrum insecticide with contact, stomach, and feeding inhibition action. It shows high activity against lepidopteran pests on crops but is not recommended for soil application.
Wear gloves, protective clothing, and goggles during handling. Avoid direct skin or eye contact to reduce exposure risk.
Prepare spray solutions in well-ventilated areas. Use calibrated equipment to ensure accurate dosage and uniform distribution.
Store in original containers with lids tightly closed. Keep in cool, dry, and secure places away from food or feed.
Contain spills with absorbent material. Dispose of residues and empty containers according to local pesticide regulations.
Avoid contamination of water bodies during spraying. Follow buffer zone requirements to reduce risks to aquatic organisms and non-target species.
In case of contact, wash skin with soap and water. If inhaled, move to fresh air and seek medical advice immediately.
