Using treated grass clippings in compost bin

I intended to use grass clippings from my lawn in the compost bin, and also small amounts to mulch shrubs. However, the lawn was treated with Dicophar broadleaved weedkiller, so does this mean I can never use the clippings in those ways? Would there be a period of time after which it would be safe to use them?

Some of the active ingredients can last for over one year and can affect shrubs and flowers if it comes into contact with foliage. It will not cause a problem under big shrubs with stems lifted off the ground.

Compost the grass separately in a black bag and test its activity by sowing a few lettuce seeds
