Description

Mevinphos is a fast-acting organophosphate insecticide and acaricide with both contact and systemic activity. Its primary value lies in its rapid knockdown effect against a broad spectrum of pests, making it a critical tool for urgent crop protection scenarios. This compound is essential for agricultural professionals and formulators managing outbreaks of sucking and chewing insects in various high-value crops. Mevinphos CAS NO 7786-34-7 is known for its potency, though its use is now highly restricted or banned in many countries due to its high toxicity.

Application

Mevinphos is utilized in agricultural pest control, primarily in formulations for crop protection. Its applications include:

• Broad-Spectrum Insecticide: Control of aphids, mites, leafhoppers, and caterpillars on a variety of crops.
• Fast-Acting Foliar Spray: Used in situations requiring rapid pest knockdown to prevent immediate crop damage.
• Systemic Pest Management: Absorption into plant tissues provides residual protection against sucking insects.
• Agricultural Formulations: Serves as an active ingredient in the manufacture of emulsifiable concentrates (EC) and other pesticide formulations.
• Research & Development: Used as a reference standard or analytical grade material in environmental and toxicological studies.
• Historical Pest Control Programs: Previously used in non-agricultural settings like forestry and vector control, now largely discontinued.

Quality Control

Our Mevinphos is produced and handled under strict quality protocols to ensure batch-to-batch consistency and purity. Quality assurance includes rigorous analytical testing against established specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your compliance and research needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its chemical nature, this material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep container tightly sealed when not in use to minimize exposure to air and moisture.
