Introduction

EM-1 (Emamectin Benzoate 5% SG) is a modern, broad-spectrum, systemic, and contact insecticide formulated as a soluble granular (SG) containing 5% emamectin benzoate. Emamectin benzoate is a powerful insecticide that belongs to the avermectin class, acting as a potent agonist of glutamate-gated chloride channels in insect neurons. By disrupting the normal flow of chloride ions across nerve cell membranes, EM-1 effectively controls a wide range of sucking and chewing pests in various crops, particularly caterpillars and lepidopteran larvae.

Active Ingredient and Mode of Action

EM-1 contains a single active ingredient: emamectin benzoate.

• Emamectin benzoate: This active ingredient belongs to the avermectin class of insecticides. It specifically targets glutamate-gated chloride channels (GluCls), which are protein receptors that regulate the flow of chloride ions across nerve cell membranes. By binding to GluCls, emamectin benzoate overstimulates the channels, leading to excessive chloride ion influx, nerve cell depolarization, paralysis, and eventually, death. Emamectin benzoate exhibits both systemic and contact activity, providing effective control of pests that feed on or are in close contact with treated plants.

Application Methods

EM-1 can be applied as a foliar spray, soil drench, or seed treatment.

• Foliar spray: Mix the recommended dosage of EM-1 with water and apply it to the foliage of plants until they are thoroughly wet.

• Soil drench: Mix the recommended dosage of EM-1 with water and apply it to the soil around the base of plants.

• Seed treatment: Mix the recommended dosage of EM-1 with water and coat the seeds before sowing.

Dosage Rates

The recommended dosage rate of EM-1 varies depending on the target pest, crop, and application method. Consult the product label for specific dosage instructions.

Precautions

When handling and applying EM-1, follow these precautionary measures to ensure safety:

• Wear protective clothing, including gloves, goggles, and a respirator.

• Avoid contact with skin and eyes.

• Do not apply the insecticide in windy conditions.

• Wash hands thoroughly after handling the product.

• Dispose of empty containers responsibly.

• Avoid using near water sources or aquatic habitats.

• Do not use on bees or other beneficial insects.

Storage and Shelf Life

Store EM-1 in a cool, dry place, away from direct sunlight and heat. When stored properly, the product has a shelf life of two years.

Conclusion

EM-1 (Emamectin Benzoate 5% SG) stands out as a versatile and effective broad-spectrum insecticide with a unique mode of action, favorable environmental profile, and compatibility with other pesticides. Its efficacy against a wide range of sucking and chewing pests, along with its systemic and contact activity, makes it a valuable tool for integrated pest management (IPM) programs. However, it is crucial to use EM-1 responsibly and in accordance with label instructions to minimize potential risks to human health and the environment.
