How does spider mite attack actually kill a plant?

Onsce the pnat ppears totally dead, is there a best-chance remedy left to try, such as cutting the branches off ain the hope that a new shoot might appear? Presumably the roots are unaffected? The only chemical remedy for red spider mite worth using is Westland Plant Rescue ready-to-use spray, which contains thiamethoxam and abamectin. It is the latter which is active against RSM. Do not bother with any other chemicals available to the amateur which claim to be active, and do not be mislead into buying Plant Rescue concentrate as this contains only thiamethoxam. In my experience, it is best to use this spray at the first sign of any RSM infection - usually a few small web strands. Check the underside of the leaves for RSM. If heavily infested, remove all leaves (if this is feasible) and spray what's left. Drastic, but it may save the plant. -- Jeff |
