Features

Effective against mosquito larvae and pupae, especially Aedes, Culex, and Anopheles mosquitoes in breeding water habitats.

Acts as a juvenile hormone mimic, disrupting normal mosquito development and preventing larvae or pupae from emerging as viable adults.

Mainly suitable for mosquito breeding sites, water containers, drains, catch basins, stagnant water, construction-site water, urban vector-control programs, and emergency dengue or malaria vector-control programs.

Application Guide

Application Areas	Target Pests	Recommended Application Rate	Application Timing
Public Health / Vector Control
Water Containers, Storage Tanks, Cisterns, Buckets, Flower Pots, Discarded Containers	Aedes Mosquito Larvae, Aedes aegypti, Aedes albopictus, Dengue Vectors, Chikungunya Vectors, Zika Vectors	Target concentration: 0.01 mg a.i./L water. Equivalent product rate for 0.5% GR: about 2 mg product/L water, equal to 2 g product/m³ water	Apply directly to mosquito breeding water according to local public health label. Re-apply according to residual efficacy, water replacement, rainfall, contamination level, and local program requirements
Drains / Catch Basins / Urban Standing Water
Drains, Catch Basins, Roadside Water, Construction-site Water, Stagnant Water	Culex Mosquito Larvae, Aedes Mosquito Larvae, Urban Mosquito Larvae, Mosquito Pupae	Clean water reference: 2 kg/ha; Polluted water reference: 4 kg/ha; Re-application interval reference: every 3 weeks	Apply when mosquito larvae are detected or when breeding sites are expected to remain wet. Use as part of routine larval source management.
Public Health Vector-control Programs
Dengue, Malaria, Zika, Chikungunya Vector-control Programs	Aedes Mosquito Larvae, Anopheles Mosquito Larvae, Culex Mosquito Larvae, Disease Vector Mosquitoes	Reference dosage: 0.01 mg a.i./L water for container habitats or 2–4 kg/ha for water-surface treatment programs	Apply before adult mosquito populations increase, especially during rainy seasons, outbreak risk periods, or after vector surveillance indicates active breeding.
Non-crop / Environmental Mosquito Breeding Sites
Ponds, Ditches, Marshy Areas, Wastewater Pools Where Registered	Mosquito Larvae, Culex Larvae, Anopheles Larvae, Aedes Larvae	2–4 kg/ha according to water quality, mosquito species, breeding-site condition, and local label	Apply only to approved mosquito breeding sites. Do not apply to sensitive aquatic habitats, drinking-water sources, aquaculture sites, or protected environments unless specifically allowed by local label and authority.
