Product Overview

Wartar 4G (Nichino Chemical India) CARTAP HYDROCHLORIDE 4% GR 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 mode of action, rapid action, long residual activity, and favorable crop safety profile.

Active Ingredient

The active ingredient in Wartar 4G is cartap hydrochloride, a carbamate insecticide that disrupts the insect's acetylcholine esterase enzyme (AChE), which is crucial for nerve transmission in insects. Cartap hydrochloride inhibits the AChE enzyme, leading to the accumulation of acetylcholine and overstimulation of the insect's nervous system, resulting in paralysis and death.

Mode of Action

Wartar 4G acts as a contact and systemic insecticide. When applied to the soil, cartap hydrochloride granules slowly release the insecticide into the surrounding soil. The insecticide then moves through the soil and can be absorbed by plant roots or taken up by insects through contact. Once inside the insect's body, cartap hydrochloride disrupts the AChE enzyme, leading to paralysis and death. Additionally, some cartap hydrochloride can be translocated throughout the plant tissues, providing protection against insects feeding on various parts of the plant.

Application Methods

Wartar 4G can be applied using various methods, including:

Soil application:

• Wartar 4G is applied uniformly to the soil around the base of the plant or broadcast over the entire planting area.

Direct application:

• In specific cases, Wartar 4G 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 Wartar 4G varies depending on the target pest species, crop type, severity of the infestation, and soil type. Generally, application rates range from 25 to 50 kilograms of product per hectare (kg/ha) for soil application and 100 to 200 g/ha for direct application.

Residual Activity

Wartar 4G 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

Wartar 4G 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

Wartar 4G is considered to have a moderate environmental impact compared to other insecticides. Cartap hydrochloride has moderate to low mobility in soil, reducing the risk of leaching into groundwater. However, it is essential to follow proper application methods and avoid excessive use to minimize potential environmental impact.

Safety Precautions

Wartar 4G 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 Wartar 4G in a cool, dry place, out of reach of children and pets. Dispose of unused insecticide and empty containers according to local regulations.
