Product Overview

Chandika (Nichino Chemical India) CHLORPYRIFOS 50% + CYPERMETHRIN 5% EC is a broad-spectrum insecticide that effectively controls a wide range of sucking and chewing insect pests in various crops, including vegetables, fruits, ornamentals, and field crops. It is known for its unique combination of active ingredients, rapid action, long residual activity, and favorable crop safety profile.

Active Ingredients

Chandika's active ingredients are chlorpyrifos and cypermethrin, two potent insecticides with different modes of action. Chlorpyrifos is an organophosphate insecticide that disrupts the insect's nervous system by inhibiting acetylcholinesterase, an enzyme essential for nerve transmission. Cypermethrin is a pyrethroid insecticide that disrupts the insect's sodium channels, leading to hyperexcitation, paralysis, and death.

Mode of Action

Chandika acts as a contact insecticide. When applied to insects or plants, chlorpyrifos and cypermethrin quickly penetrate the insect's body through contact. Chlorpyrifos disrupts the insect's nervous system, while cypermethrin disrupts its sodium channels, leading to a rapid knockdown effect and long-lasting control.

Application Methods

Chandika can be applied using various methods, including:

• Foliar spraying: This involves spraying the insecticide directly onto the foliage of the plants to control insects feeding on the leaves, stems, and flowers.

• Soil drenching: This method involves applying the insecticide to the soil around the base of the plant, targeting insects living in the soil or feeding on the roots.

• Direct application: In specific cases, Chandika can be applied directly to insect infestations, such as spraying to control termites or injecting into the stems of infested plants.

Application Rates

The application rate of Chandika varies depending on the target pest species, crop type, severity of the infestation, and application method. Generally, application rates range from 250 to 500 milliliters of product per hectare (ml/ha) for foliar spraying, 500 to 1000 ml/ha for soil drenching, and 100 to 200 ml/ha for direct application.

Residual Activity

Chandika has a long residual activity, typically lasting for several weeks or months, depending on environmental conditions and the target pest species. This provides effective insect control for an extended period, reducing the need for multiple insecticide applications.

Crop Safety

Chandika is considered safe for use on a wide range of crops, including vegetables, fruits, ornamentals, and field crops. However, it is important to follow label directions and consult with local experts to ensure crop compatibility.

Environmental Considerations

Chandika is considered to have a moderate environmental impact compared to other insecticides. Chlorpyrifos and cypermethrin have moderate mobility in soil, with the potential for leaching into groundwater under certain conditions. Additionally, chlorpyrifos and cypermethrin are moderately persistent in the environment, breaking down over time into non-toxic compounds.

Safety Precautions

Chandika is a moderately toxic insecticide, and it is crucial to follow all safety precautions when handling and applying the product. Personal protective equipment (PPE), including gloves, goggles, and a respirator, should be worn when mixing, loading, and applying the insecticide. Avoid contact with skin and eyes, and wash thoroughly after handling.

Storage and Disposal

Store Chandika in a cool, dry place, out of reach of children and pets. Dispose of unused insecticide and empty containers according to local regulations.
