Abstract
Commercial rose growers in the United States are under increasing pressure to use reduced-risk pesticides that have minimum re-entry intervals following application.
Along with obvious environmental pressures to reduce toxic pesticide use, the growers are operating under a special exemption that allows re-entry within a pesticide re-entry restriction period.
It is therefore of paramount importance to develop and test reduced risk pesticides that have minimal re-entry intervals following their application.
In addition, spider mites have developed resistance to the industry standard miticide (avermectin) used to control spider mites in greenhouse roses.
The experiment reported here evaluated the efficacy of new reduced-risk and conventional miticides on the control of two spotted spider mites, Tetranychus urticae. Many reduced-risk and conventional products showed good to excellent effectiveness.
