Timing & weather

Once applied, Sumilarv 0.5G Sachets (WSP) will be unaffected by dry, hot, cold or sunny conditions and will begin working when the catch basin is flooded during rain events until the active ingredient degrades below effective levels.
Treatments should be made every 4-5 weeks for water retention or water detention ponds depending on the volume water or frequency of rain events.
