To kill insects on the roots, it is well to clear away the soil as far as possible from them, and to saturate the place with soapsuds or ammoniacal solutions; soot, quicklime, or other applications to the soil would also prove useful.
Other remedies that have been suggested are the drainings of stables, and grafting-clay plastered over the bark.
