Product Overview

Thanedar is a broad-spectrum insecticide developed by Gujarat Insecticides that provides effective control of a wide range of sucking and chewing insects, including aphids, thrips, whiteflies, caterpillars, and beetles, in various crops, including vegetables, fruits, and ornamentals. It contains a combination of two active ingredients: fipronil and imidacloprid.

Fipronil is a phenylpyrazole insecticide that disrupts insect development and feeding behavior. It binds to a specific receptor in insects, blocking the normal flow of chloride ions through the nervous system, leading to paralysis and death in insects.

Imidacloprid is a neonicotinoid insecticide that disrupts the nicotinic acetylcholine receptor (nAChR), a crucial component of the insect nervous system. It binds to this receptor, blocking the normal binding of acetylcholine, a neurotransmitter responsible for transmitting nerve impulses. This disruption of acetylcholine signaling leads to an overexcitation of the nervous system, resulting in paralysis and death in insects.

The combination of fipronil and imidacloprid in Thanedar provides synergistic insecticidal activity, meaning that the combined effect of the two insecticides is greater than the sum of their individual effects. This synergy enhances the overall effectiveness of Thanedar against a wide range of pests.

Mode of Action

Thanedar's insecticidal activity stems from the combined action of its two active ingredients:

• Fipronil: Disrupts insect development and feeding behavior by interfering with chloride ion flow in the nervous system.

• Imidacloprid: Disrupts the nicotinic acetylcholine receptor (nAChR), leading to overexcitation of the nervous system.

Key Features and Benefits

Thanedar offers several advantages that make it a popular insecticide in various agricultural and horticultural settings:

• Broad-spectrum efficacy: Effectively controls a wide range of sucking and chewing insects, including aphids, thrips, whiteflies, caterpillars, and beetles, providing comprehensive pest management in vegetables, fruits, and ornamentals.

• Long-lasting residual protection: Offers long-lasting residual protection of up to 30 days, ensuring effective pest suppression and minimizing crop damage. The active ingredients bind to plant tissues and soil particles, providing extended protection against re-infestation.

• Synergistic insecticidal activity: The combination of fipronil and imidacloprid provides synergistic action, enhancing the overall effectiveness against a wide range of pests.

• Contact and systemic action: Provides both contact and systemic action, effectively controlling exposed pests on the plant surface and those feeding within the plant tissues. Fipronil acts primarily through contact action, while imidacloprid offers systemic protection, moving throughout the plant system and providing protection to all parts of the plant.

• Low application rates: Effective at low application rates, reducing the environmental impact and minimizing residue levels in soil and water bodies.

• Compatible with a wide range of crop protection chemicals: Can be used in conjunction with various fungicides, herbicides, and other insecticides, allowing for flexible pest management strategies.

Application Guidelines

Thanedar is typically applied as a foliar spray or soil drench, ensuring thorough coverage of the target crop and pests. The recommended dosage varies depending on the specific target pests, pest density, crop stage, and soil type. Generally, a concentration of 250-500 ml/ha is recommended for foliar application and 100-200 ml/ha for soil drench application. Application timing should be during the active pest infestation stage, typically 3-4 days after the first detection of pests.

Safety Precautions

Thanedar is classified as moderately toxic, so it is essential to follow safety precautions during handling and application:

• Personal Protective Equipment (PPE): Wear gloves, a mask, and overalls to minimize exposure to the product.

• Avoid Direct Contact: Avoid direct contact with skin and eyes to prevent irritation.

• Weather Conditions: Do not apply during hot or windy conditions to ensure proper dispersion and prevent drift.

• Water Resources: Avoid applying near water bodies or waterways to prevent contamination.

• Waste Disposal: Dispose of empty containers and unused products responsibly according to local regulations to protect the environment.

Overall, Thanedar (Gujarat Insecticides) fipronil + imidacloprid is a versatile and effective insecticide that provides broad-spectrum, long-lasting, synergistic, contact, and systemic protection against a wide range of sucking and chewing insects in various crops, including vegetables, fruits, and ornamentals. Its low application rates, compatibility with other crop protection chemicals, and flexible application methods make it a valuable tool for integrated pest management (IPM) programs in agricultural and horticultural settings.
