Acarin (Nichino Chemical India) SPIRODICLOFEN 22.9% SC is a broad-spectrum insecticide that effectively controls a wide range of sucking and chewing insect pests in various crops, including vegetables, fruits, and ornamentals. It is known for its unique mode of action, rapid action, long residual activity, and favorable crop safety profile.

Active Ingredient

Acarin's active ingredient is spirodiclofen, a tetronic acid insecticide that disrupts the insect's lipid metabolism, affecting their energy production and leading to death. Spirodiclofen is particularly effective against spider mites, but it also controls a range of other sucking and chewing insects.

Mode of Action

Acarin acts as a contact and translaminar insecticide. When applied to insects or plants, spirodiclofen quickly penetrates the insect's body through contact or ingestion. It interferes with the insect's lipid biosynthesis, disrupting energy production and causing paralysis and eventual death. Additionally, spirodiclofen can be absorbed by the plant and translocated to the upper and lower surfaces of the leaves, providing protection against insects feeding on various parts of the plant.

Target Insects

Acarin effectively controls a broad spectrum of sucking and chewing insect pests, including:

• Sucking Insects: Spider mites, aphids, thrips, whiteflies, mealybugs, and scale insects.

• Chewing Insects: Diamondback moth, tobacco caterpillar, and other leaf miners, borers, and cutworms.

Application Methods

Acarin 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: This method involves applying the insecticide directly to spider mite infestations, such as spraying directly onto infested leaves or dipping infested plants in the insecticide solution.

Application Rates

The application rate of Acarin varies depending on the target insect species, crop type, and severity of the infestation. Generally, application rates range from 100 to 200 milliliters of product per hectare (ml/ha) for foliar spraying and 200 to 400 ml/ha for soil drenching.

Residual Activity

Acarin 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

Acarin is considered safe for use on a wide range of crops, including vegetables, fruits, and ornamentals. It is particularly beneficial for crops that require the presence of pollinators, as it has a low impact on beneficial insect populations.

Environmental Considerations

Acarin is considered to have a relatively low environmental impact compared to other insecticides. Spirodiclofen has low solubility in water, reducing the risk of runoff and leaching into groundwater. Additionally, spirodiclofen is moderately persistent in the environment, breaking down over time into non-toxic compounds.

Safety Precautions

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