Kenso Kencis 1 L is an insecticide formulated as an emulsiable or water-soluble concentrate containing cypermethrin—a pyrethroid-class active ingredient with both contact and stomach poisoning action against insects.
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.
Vegetable & Foliage Crops
Mealybugs, aphids, and caterpillars such as Setothosea asigna.
Suitable for leafy vegetables—commonly used via foliar spray when pest infestation is noticeable.
Oil Palm Plantations
Bagworms (Metisa plana) are effectively controlled using the 50 g/L EC version.
Caterpillars, managed using the 55 g/L EW formulation.
From the OKB Project description:
Use cyclic rotation for improved effectiveness.
Spray when pests reach “Action Threshold Level” and preferably when larvae are young.
If needed, re-spray every 14 days, up to a maximum of 4 applications per year.
Recommended dosage: ~100 mL diluted mixture sprayed over each palm leaf base and frond tips.
Mode of action: Rapid knockdown effect through both contact and ingestion.
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.
Optimal timing: Apply when insects are young and before damage is extensive.
Resistance management: Rotate with insecticides from different IRAC classes to help delay resistance.
