Fast-acting insecticide for rapid aphid and pest control in wheat fields.

Key Product Features:

1.      Fast-acting and broad-spectrum control: Provides rapid knockdown of wheat aphids and other piercing-sucking pests, ensuring quick pest suppression.

2.      Multiple modes of action: Combines fumigant, stomach, and contact toxicity, delivering effective coverage and deep penetration for enhanced pest control.

3.      Neurotoxic mechanism: Irreversibly inhibits acetylcholinesterase (AChE), leading to paralysis and death, ensuring high efficacy and reliable results.

Detailed Description:

Dichlorvos 77.5% EC is a broad-spectrum organophosphate insecticide with fumigant, stomach, and contact toxicity, registered for controlling aphids (Aphididae) on wheat. It functions by irreversibly inhibiting acetylcholinesterase (AChE), an enzyme critical for neurotransmission in insects, leading to acetylcholine accumulation at nerve synapses, causing paralysis and eventual death. With its rapid knockdown effect, Dichlorvos provides quick pest suppression, making it particularly effective against piercing-sucking pests such as aphids, whiteflies, and thrips. Due to its high volatility, it exhibits both direct contact and fumigant activity, ensuring broad coverage and penetration in treated areas. Proper application at the early stages of infestation maximizes effectiveness while minimizing resistance risks.

Effective Against:

·         Wheat Aphids (Aphididae): Major pests that reduce plant vigor and spread viral diseases.

·         Whiteflies (Aleyrodidae): Sap-sucking insects that weaken plants and cause secondary infections.

·         Thrips (Thysanoptera): Pests that damage leaves and flowers, reducing crop yield.

Registered Scope and Method of Use:

Technical Application Requirements:

1. Early Application & Uniform Spraying: Apply at the initial stage of aphid infestation in wheat. Dilute with water and spray evenly over the entire plant to ensure thorough coverage.

2. Avoid Drift to Sensitive Crops: Dichlorvos EC can cause phytotoxicity to sorghum, corn, legumes, roses, cucurbit seedlings, and willows. Apply only in calm weather to prevent spray drift onto these sensitive plants.

3. Optimal Weather Conditions: Avoid spraying in windy conditions or before rainfall to prevent reduced efficacy and unintended exposure.

4. Resistance Management: Rotate with insecticides from different IRAC groups to prevent resistance buildup and maintain long-term effectiveness.
