Karanjin
Description
Mode of action
Karanjin belongs to the class of furanoflavonoids extracted from the seeds of the Karanja tree (Pongamia pinnata). This substance acts as a natural insecticide and acaricide, possessing the unique ability to disrupt the metabolism and feeding processes of harmful insects.
The mechanism of action is based on an antifeedant effect. When the substance comes into contact with the insect's body or is ingested, the active components inhibit larval development and interfere with the hormonal balance of the pest.
Unlike synthetic neurotoxins, karanjin acts gently, gradually reducing the viability of pest populations within the agroecosystem. This makes it a valuable tool for managing resistance to conventional pest control methods.
The substance also exhibits moderate fungicidal activity, suppressing the development of certain pathogenic fungi on leaf surfaces. It acts as a mild inhibitor, creating an unfavorable environment for colonization by plant pathogens.
The environmental safety of this compound is ensured by its rapid degradation in the soil under the influence of sunlight and microorganisms, which prevents the accumulation of toxic residues in crops.
What it targets
Karanjin is effective against a wide range of Lepidoptera (caterpillars), aphids, whiteflies, and certain types of spider mites. It is commonly used in integrated pest management programs for vegetable and fruit crops.
Rates and timing
Application timing depends on the pest life cycle; it is recommended to conduct treatments in the evening or early morning. Dosage rates vary based on the specific concentration of the active ingredient in the commercial formulation.
Restrictions
Using karanjin requires standard safety precautions, including the use of protective clothing and respirators. The product should not be mixed with highly alkaline substances to maintain its biological efficacy.
