Fasis

Mechanism of Action and Molecular Efficiency

The insecticide "Phasis" is a specialized tool for orchard pest management based on fenoxycarb (carbamate group). Unlike classic neurotoxins that cause paralysis, this agent mimics insect juvenile hormones. Upon contact with pupae or larvae, the active substance disrupts metamorphosis, preventing the insect from reaching the adult stage or completing its molting process. This makes it highly effective against hidden pests such as the San Jose scale, leaf rollers, and the codling moth.

Technological Formulation Advantages

• Formulation: Water-dispersible granules (WDG) ensure suspension stability. They dissolve rapidly in the spray tank, preventing nozzle clogging and ensuring uniform coverage of leaf surfaces.
• Contact Activity: The product acts via direct contact with the pest and through contact with treated surfaces. Fenoxycarb exhibits a pronounced ovicidal effect, sterilizing laid eggs and significantly reducing pest populations in subsequent generations.

Application Best Practices

To achieve maximum efficacy in apple orchards, the protocol requires a maximum of two applications per season. The pre-harvest interval is 30 days, which must be considered when planning the protection schedule. The product shows high resistance to rainfall, making it reliable under varying weather conditions.
