The best remedy against borers is to practice preventive measures and intervene quickly when they are identified. Prevention means regularly examining plants for signs of borer damage and removal of weakened or dead stems and branches, as these can act as a source of infestation. If borers are found, promptly prune the stem or branch and twig several inches back past any visible signs or activity. In some cases, spot treatments with insecticides may be necessary for severe infestations. Finally, keep irrigation up-to-date to keep plants healthy; this reduces their susceptibility to borer attacks.
