Chemical Control:
Horticultural oils and insecticidal soaps are recommended, but have not been proven to control the Myoporum Thrips. Pesticides containing spinosad, (Conserve), or imidacloprid, (Merit), provide the best control and significantly reduce the number of thrips. However pesticides containing abamectin, (Avid), provide some control over time, but does not dramatically reduce populations.*
*With all of these options large reductions in predatory insects occurred. The plant material must be sprayed at least twice per season to get noticeable control, and the spray coverage must be very good. May not be the most cost effective option.
