Product Overview

Crux (Nichino Chemical India) Thiamethoxam 25% WG is an advanced systemic insecticide that effectively controls a wide range of sucking and chewing insect pests in various crops, including vegetables, fruits, and ornamentals. It is renowned for its unique mode of action, rapid action, extended residual activity, and favorable crop safety profile.

Active Ingredient

Crux's active ingredient is thiamethoxam, a neonicotinoid insecticide that disrupts the insect's nicotinic acetylcholine receptor (nAChR), a crucial component of the insect's nervous system. This disruption of the nAChR leads to uncontrolled muscle contractions, paralysis, and eventual death. Thiamethoxam is highly systemic, meaning it is absorbed and translocated throughout the plant tissues, providing protection against insects feeding on various plant parts.

Mode of Action

Crux acts as a contact and systemic insecticide. When applied to insects or ingested, it swiftly enters the insect's body and binds to the nAChR in the nervous system. This disruption of the nAChR prevents the transmission of nerve impulses, leading to uncontrolled muscle contractions, paralysis, and eventual death. Additionally, thiamethoxam is absorbed by the plant and translocated throughout the plant tissues, providing protection against insects feeding on various plant parts.

Application Methods

Crux 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.

Application Rates

The application rate of Crux varies depending on the target insect species, crop type, and severity of the infestation. Generally, application rates range from 250 to 500 grams of product per hectare (g/ha) for foliar spraying and 500 to 1000 g/ha for soil drenching.

Residual Activity

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

Crop Safety

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

Environmental Considerations

Crux is considered to have a relatively low environmental impact compared to other insecticides. Thiamethoxam has low mobility in soil, reducing the risk of leaching into groundwater. Additionally, thiamethoxam is moderately persistent in the environment, breaking down over time into non-toxic compounds.

Safety Precautions

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