Insecticide FAS, a.e., (Alpha-cypermethrin, 100 g/l)

Technical Overview of FAS Insecticide

FAS insecticide, featuring Alpha-cypermethrin (100 g/l), is a high-performance contact insecticide designed for cabbage protection. Manufactured by Nanjing Essence Fine-Chemical Co. Ltd, this formulation provides a robust defense against a wide array of pests, including cabbage moths, aphids, flea beetles, and loopers.

Inside the Formulation: Why 100 g/l Matters

The formulation is presented as an emulsifiable concentrate (EC), a standard choice for delivering efficient knockdown results. Alpha-cypermethrin acts by modulating sodium channels in the nervous system of insects. Once the chemical makes contact with the pest, the insect becomes immobilized rapidly, stopping damage to the crop almost immediately.

• Rapid Contact Action: Being a contact-based solution, it is ideal for rapid response during pest outbreaks on cabbage fields.
• Performance in the Field: The 100 g/l concentration ensures that even at standard application rates, the efficacy remains high against resistant or difficult-to-reach pest populations.
• Stability: The EC formulation ensures that the active ingredient remains evenly distributed in the spray tank, preventing clogging and ensuring uniform application across the crop canopy.

Application and Safety Guidelines

Effective pest management with FAS requires high-quality spraying during the vegetative stage. Because the product relies on contact, coverage is the priority—ensuring the spray reaches both the top and the underside of leaves is essential. With a maximum of two treatments per season, it is recommended to rotate this product with other classes of insecticides to prevent the development of pest resistance. A 30-day pre-harvest interval must be strictly observed to ensure safety standards are met, as the product is classified as a Class 2 hazard.
