Product Overview

Wartap 50 SP is a systemic broad-spectrum insecticide belonging to the Nereistoxin analogue group effective on both sucking insects and biting insects by contact or ingestion. Wartap 50 SP on entering the pest body attacks on a nicotinic acetylcholine receptor/ion channel complex on synapse in the central nervous system.

Active Ingredient

The active ingredient in Wartap 50 SP 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

Wartap 50 SP 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

Wartap 50 SP can be applied using various methods, including:

• Soil application: Wartap 50 SP is applied uniformly to the soil around the base of the plant or broadcast over the entire planting area.
• Direct application: In specific cases, Wartap 50 SP 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 Wartap 50 SP 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

Wartap 50 SP 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

Wartap 50 SP 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

Wartap 50 SP 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

Wartap 50 SP 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 Wartap 50 SP in a cool, dry place, out of reach of children and pets. Dispose of unused insecticide and empty containers according to local regulations.
