Termidor SC is not labeled for use on any bearing fruit trees. We would not recommend eating any fruit grown on the treated trees for at least 1 year.
Termites do not normally attack live, healthy trees so you most likely will not find any products that will work as a ground barrier around the trees. Most people are primarily concerned with protecting the big investment, their home, and Termidor SCwould be the product to use for that. It is only labeled to be used adjacent to the structure though. Please take a moment to read over our article on "How to do a Termite Treatment" for complete details.
