Red Sun’s alpha-Cypermethrin is a pyrethroid insecticide composed of active isomers of cypermethrin. It is used as raw material for pesticide formulations and is not intended for direct application to crops or other sites.
The product acts on sodium channels in insect nerve cells, causing repetitive discharges and disruption of normal signaling. This leads to loss of coordination, paralysis, and death of target pests. It functions effectively through both contact and ingestion.
Alpha-Cypermethrin provides control of Lepidoptera, Coleoptera, and Diptera pests. It shows a strong knockdown effect at low use rates and supports multiple formulation options. The compound is stable under neutral and acidic conditions and retains effectiveness during storage for over two years.
Red Sun’s alpha-Cypermethrin is a pyrethroid insecticide designed for use in pesticide formulations. The product is based on active isomers of cypermethrin and is positioned to meet diverse agricultural and industrial needs.
Alpha-Cypermethrin interferes with sodium channels in insect nerve cells, leading to rapid knockdown. Field results show pest paralysis within hours of exposure, followed by effective mortality in a short period.
The compound is stable under neutral and acidic conditions but degrades in alkaline environments. It shows low mobility in soil and minimal residue on crops when formulated correctly, supporting safe rotation practices.
The product demonstrates reliable control of Lepidoptera, Coleoptera, and Diptera pests. It can be applied across cotton, soybeans, fruit trees, and vegetables, offering flexibility for different cropping systems.
Alpha-Cypermethrin serves as a base material for a range of formulations such as EC, SC, and WP. It can be combined with other active ingredients, enabling broader pest management strategies and reducing resistance risks.
Red Sun supports production with consistent annual capacity and strict compliance standards. Multi-site manufacturing and quality certifications ensure reliable delivery for B2B procurement partners worldwide.
Red Sun’s alpha-Cypermethrin is a pyrethroid insecticide used as a raw material in pesticide production. Its manufacturing process allows for efficient isolation of active isomers, ensuring consistent supply for agricultural and industrial applications.
Alpha-Cypermethrin is applied in formulations that protect cotton, soybeans, fruit trees, and vegetables. It targets Lepidoptera, Coleoptera, and Diptera pests, supporting pest management in large-scale farming systems.
The product serves as a base ingredient for emulsifiable concentrates, suspension concentrates, and wettable powders. It enables flexibility in creating customized solutions for different markets.
The compound’s isomer composition supports stable processing for large-scale production. It integrates into standardized pesticide manufacturing chains without requiring complex separation procedures.
Alpha-Cypermethrin is used in studies exploring new pesticide mixtures and resistance management strategies. Its stable structure makes it a reliable candidate for product innovation.
Contact may cause tingling on skin, especially around the mouth and nose. Large exposure can lead to headache, dizziness, nausea, tremors, or in severe cases convulsions, coma, or shock.
If skin contact occurs, use talc to absorb, then wash with soap and water. If in eyes, rinse with clean water for at least 15 minutes. No specific antidote exists; treatment is symptomatic. For ingestion, gastric lavage may be used. Do not induce vomiting.
Store in a ventilated, cool, and dry place. Keep away from food and raw materials. Avoid mixing with alkaline substances.
The product is toxic to fish, bees, and silkworms. Do not contaminate water bodies or flowering crops. Avoid spraying near rivers, ponds, or natural enemy release areas. Do not wash equipment in waterways.
Follow pesticide safety guidelines during application. Wear protective clothing, gloves, and a mask. Do not eat or drink during spraying. Wash skin and rinse mouth with clean water after work.
Children, pregnant women, and nursing women must not handle pesticides. Restrict access during storage and application.
Cover spills with absorbent material such as sand, soil, or sawdust. Collect with a broom and dispose of safely.
Alternate use with non-pyrethroid insecticides to reduce resistance risks.
