Not approved for use on Spring Beans.

I wouldn't expect any damage to following autumn cereal crop (propyzamide would break down as soil temps increase).

Not familiar with Rats tail fescue, but would think the same persistency characteristics that make it safe for autumn cereals would also reduce its efficacy against spring germinating grass-weeds.

Kerb isn't approved in spring beans & has to be pre-em in winters.

Do contact graminicides (Falcon, Laser etc) not control rats tail fescue? Defy has an EAMU for pre em use in spring beans IIRC.
