Introduction

Pager (Diafenthiuron 50% WP) is a versatile, broad-spectrum, systemic, and contact insecticide formulated as a wettable powder (WP) containing 50% diafenthiuron. Diafenthiuron belongs to a unique chemical group known as the benzoylureas and acts as a potent disruptor of insect energy production. By interfering with the mitochondrial electron transport chain, Pager effectively controls a wide range of sucking pests, particularly aphids, whiteflies, and thrips, in various crops, including cotton, vegetables, fruits, and ornamentals.

Active Ingredient and Mode of Action

Pager contains a single active ingredient: diafenthiuron.

• Diafenthiuron: This active ingredient belongs to the benzoylurea class of insecticides. It specifically targets the mitochondrial electron transport chain, a series of protein complexes that generate energy for cells. By inhibiting the activity of specific enzymes in the electron transport chain, diafenthiuron disrupts cellular respiration, leading to energy depletion, paralysis, and eventually, death of the insect. Pager exhibits both systemic and contact activity, providing effective control of pests that feed on or are in close contact with treated plants.

Application Methods

Pager can be applied as a foliar spray or soil drench.

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

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

Dosage Rates

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

Precautions

When handling and applying Pager, 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 Pager in a cool, dry place, away from direct sunlight and heat. When stored properly, the product has a shelf life of two years.

Benefits of Pager

Pager stands out as a valuable tool for integrated pest management (IPM) programs, offering several notable benefits:

1. Broad-spectrum control: Effective against a wide range of sucking pests.

2. Dual activity: Systemic and contact activity for effective control of both feeding and non-feeding pests.

3. Fast-acting and long-lasting residual activity: Provides rapid knockdown and extended control of pests.

4. Selective to beneficial insects: Relatively low toxicity to mammals and beneficial insects.

5. Compatible with other pesticides.

Conclusion

Pager (Diafenthiuron 50% WP) proves to be a valuable tool for integrated pest management (IPM) programs, offering effective control of a wide range of sucking pests while minimizing potential environmental risks. Its unique mode of action, selectivity to beneficial insects, and long-lasting residual activity make it a preferred choice for sustainable pest management practices. However, it is crucial to use Pager responsibly and in accordance with label instructions to maximize its benefits and minimize potential hazards.
