Technical Specification of "Fishka" Insecticide

The "Fishka" insecticide, manufactured by Zhejiang Agrin Company Ltd., utilizes alpha-cypermethrin, a potent synthetic pyrethroid known for its reliable performance in cereal and oilseed rape protection. The mode of action is direct: it targets the insect's nervous system by inhibiting sodium channels within nerve cell membranes, leading to rapid depolarization and paralysis of the target pest.

Formulation Advantage: Water-Dispersible Granules

The choice of water-dispersible granules (WG) over liquid concentrates is a strategic design decision that offers several agronomic benefits:

• Excellent solution stability: the granules dissolve rapidly, preventing nozzle clogging and ensuring even application.
• Precise dosage control: eliminates the measurement errors common with viscous liquid formulations.
• Reduced phytotoxicity: the absence of heavy organic solvents minimizes potential stress on the crop during the vegetative stage.

Field Performance and Application Mechanics

As a contact-action insecticide, "Fishka" provides an immediate "knockdown" effect. Once it comes into contact with pests such as rape blossom beetles, wheat aphids, or bugs, feeding ceases almost instantly. Given the contact nature of the product, uniform coverage of the foliage is essential to maximize efficacy against thrips and aphids.

The product is optimized for up to two applications per season, making it a versatile tool for managing pest population surges in winter wheat, winter barley, and winter rape. With a 30-day pre-harvest interval, it provides the necessary protection while ensuring compliance with stringent residue standards at harvest time.
