Active Ingredient & Formulation

• Cypermethrin 5.5% EW (Emulsion-Water): According to Farm Doktor, this variant targets pests like mealybugs, aphids, and caterpillars (e.g., Setothosea asigna), and is available in a 1 L bottle.

• Cypermethrin 50 g/L EC (Emulsifiable Concentrate): Used predominantly in oil palm plantations to control bagworms (Metisa plana). This formulation is also offered in a 1 L pack.

• Cypermethrin 55 g/L EW: Similar in function, designed for caterpillar control, especially in oil palm operations.

Given the overlapping brand name "Kencis" and pack size (1 L), it’s likely these are variant formulations for different target pests and crops.

• Protective measures: Avoid using near food or where children and pets have access. Always wear PPE such as gloves, mask, and safety goggles—and adhere strictly to label directions.
