Overview
Emamectin Benzoate is a semi-synthetic derivative of avermectin, developed to enhance insecticidal activity and stability. It is widely recognized for its high efficacy against a broad spectrum of pests, particularly Lepidoptera larvae. Due to its systemic action, it is absorbed by plants, providing long-lasting protection. This compound is favored in integrated pest management (IPM) programs due to its low environmental persistence and reduced risk to non-target organisms compared to older pesticides. Its mode of action involves binding to GABA and glutamate-gated chloride channels, leading to paralysis and death of pests.
Physical and Chemical Properties
Emamectin Benzoate is a white to pale yellow crystalline powder with a molecular weight of 1008.24 g/mol. It melts at 141-146°C and is soluble in organic solvents like acetone and methanol but has limited solubility in water. The compound is stable under normal storage conditions but degrades under strong UV light or extreme pH levels. Its low volatility reduces the risk of airborne exposure, making it safer for applicators. The benzoate salt form enhances its stability and solubility, improving formulation flexibility.
Main Applications
Emamectin Benzoate is predominantly used in agriculture to control pests in crops such as cotton, soybeans, vegetables, and fruits. It is effective against pests like Helicoverpa armigera, Spodoptera litura, and Plutella xylostella. In addition to foliar sprays, it is used in seed treatments and soil applications. Its systemic activity ensures protection even for new plant growth. The compound is also employed in forestry and horticulture to manage invasive species while minimizing harm to beneficial insects like pollinators.
Safety and Storage
Emamectin Benzoate is classified as moderately toxic (WHO Class II). It can cause irritation to the skin, eyes, and respiratory tract. Proper PPE, including gloves, goggles, and masks, is essential during handling. Store the compound in a cool, dry place, away from food and feed. Containers should be tightly sealed to prevent moisture absorption. Spills should be contained and cleaned immediately using inert absorbents. Disposal must comply with local environmental regulations to avoid contamination.
B2B Procurement Guide
When procuring Emamectin Benzoate, prioritize suppliers with ISO or GMP certifications to ensure quality. Request batch-specific certificates of analysis (CoA) to verify purity (typically 90-95%). Consider logistics: the product should be transported in sealed, moisture-proof containers. Bulk buyers may negotiate prices, especially for quantities above 100 kg. Monitor regulatory updates, as restrictions may apply in certain regions. Sample testing is recommended before large-scale purchases to confirm efficacy and compatibility with existing formulations.
