Is it safe to use BTI Mosquito Dunks in water barrels to use in a garden?

Using 275 gallon IBC container to gather rainwater from roof. Using 1 dunk per container. Also have 55 gallon water barrel for watering lettuce. 1 dunk for the waterbarrel.


The BTI Mosquito Dunks are often used one per barrel as it slowly dissolves releasing the bacteria for control of mosquito. They are deemed organic and environmentally safe.
