Distance IGR

Distance affects all pest insect life stages, including eggs, nymphs/larvae, pupae and adults. Distance does not control adults, but greatly reduces their production of viable eggs due to its strong transovarial activity. In whitefly, transovarial activity begins within one day after adults contact or ingest Distance residues. Distance is also ovicidal and inhibits metamorphosis of nymphs, larvae and pupae into adults. Since Distance is an Insect Growth Regulator (IGR), activity depends on the insect’s development. Therefore, evidence of activity may be slower than with typical contact insecticides, especially when large numbers of late instars are present at time of application.

Distance also has strong translaminar activity on a variety of ornamental plants, including poinsettia, hibiscus, gerbera daisy and chrysanthemums. Distance residues applied to the upper leaf surface will rapidly penetrate the leaf cuticle, and can subsequently be ingested by immature and adult insects feeding on the lower leaf surface (eg. whitefly). Therefore, even in cases where it is difficult to achieve thorough underleaf spray coverage, Distance can still provide highly effective control.

Distance is intended for use in Integrated Pest Management (IPM) or Integrated Resistance Management (IRM) programs. Distance will not control adult insects, and it is recommended to be used in combination and/or rotation with other IPM or IRM materials. Contact your local state extension service for details.
