1. A method of controlling arthropod or nematode pests in trees which comprises injecting into the trunk of a tree an effective amount of a composition, consisting of:
emamectin benzoate from 8 to 10% w/v;
a non-ionic/anionic surfactant mixture at about 2% w/v;
at least one stabilization agent at about 0.5% w/v; and
a solvent system forming the remainder of the composition wherein the major amount of the solvent system is a dipropylene glycol monomethylether isomer mixture which is at least 75 wt. % of the solvent system; and
wherein the emamectin benzoate maintains a controlled translocation to the leaves of the tree for at least one year; and
the anionic surfactant is selected from at least one sulfated or phosphated tristyrylphenolethoxylates having an average of 6 to 20 oxyethylene units and salts thereof.
