We have just had a really bad outbreak of buttercups in our paddocks treated with a chemical spray, we think MCPA. The last time we had it done, four years ago, we were told to keep the horses off it for at least ten days. This time the advice is for three days. We have been reading up on the spray on the internet and the phrase "it has a field half-life of 14 days to one month" comes up, which, to us, means three days is not enough. The data does also say about very low toxicity to birds and bees etc, which would suggest it would not harm the horses either, though it does make weeds such as buttercup and ragwort more palatable, and therefore more likely to be eaten. This is only the second time we have had to have the paddocks sprayed and have no other experience of it. Input welcomed.
