Product Overview

Xact (Nichino Chemical India) CHLORPYRIFOS 50% EC is a broad-spectrum insecticide that effectively controls a wide range of sucking and biting insects in various crops, including vegetables, fruits, ornamentals, and field crops. It is known for its unique mode of action, rapid action, long residual activity, and favorable crop safety profile.

Active Ingredient

Xact's active ingredient is chlorpyrifos, an organophosphate insecticide that disrupts the insect's nervous system by inhibiting the enzyme acetylcholinesterase. Acetylcholinesterase is essential for nerve transmission, and its disruption leads to paralysis and death of the insect. Chlorpyrifos is particularly effective against sucking insects, such as aphids, whiteflies, and thrips, but it also controls a variety of biting insects.

Mode of Action

Xact acts as a contact and stomach insecticide. When applied to insects or plants, chlorpyrifos quickly penetrates the insect's body through contact or ingestion. Chlorpyrifos then binds to the enzyme acetylcholinesterase, preventing it from breaking down acetylcholine, a neurotransmitter. The accumulation of acetylcholine leads to overstimulation of the insect's nervous system, resulting in paralysis and death. Additionally, Xact can be absorbed by the plant and translocated throughout the plant tissues, providing protection against insects feeding on various parts of the plant.

Application Methods

Xact 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.

• Seed treatment: This method involves treating seeds with the insecticide before planting, providing protection against soil-borne insects and early-season pests.

• Direct application: In specific cases, Xact can be applied directly to insect infestations, such as applying granules to the base of infested stems or injecting into the stems of infested plants.

Application Rates

The application rate of Xact 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, 100 to 200 ml/ha for seed treatment, and 100 to 200 ml/ha for direct application.

Residual Activity

Xact 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

Xact is considered safe for use on a wide range of crops, including vegetables, fruits, ornamentals, and field crops, with the exception of certain cucurbit crops, such as pumpkins, cucumbers, and melons.

Environmental Considerations

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

Safety Precautions

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