Description

Emamectin is a highly effective semi-synthetic insecticide derived from the avermectin family of natural products. Its primary value lies in its exceptional potency and broad-spectrum activity against a wide range of lepidopteran pests, even at very low application rates. This product is essential for agricultural professionals and formulators seeking reliable crop protection solutions. Emamectin CAS NO 137335-79-6 is a key active ingredient in modern integrated pest management programs.

Application

Emamectin is widely used as a powerful insecticide and acaricide across multiple sectors. Its primary applications include:

• Agricultural Crop Protection: Control of lepidopteran pests (e.g., armyworms, loopers, diamondback moth) on vegetables, fruits, cotton, and soybeans.
• Forestry Management: Protection of trees from defoliating insects such as gypsy moths and spruce budworms.
• Ornamental Plant Protection: Use in nurseries and greenhouses to safeguard ornamental plants and flowers from mite and insect infestations.
• Technical Grade Material: Serves as the key active ingredient for the formulation of emulsifiable concentrates (EC), suspension concentrates (SC), and other end-use products.
• Public Health Pest Control: Component in formulations targeting mosquito larvae and other public health pests in specific regulated programs.

Quality Control

Our Emamectin is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC for precise assay determination and impurity profiling. A Certificate of Analysis (COA) detailing purity, related substances, and physical parameters is provided with each shipment to guarantee compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
