Actara ® by Syngenta has recently been registered in Arizona for the first time (7/13/01). It is a foliar material designed for whitefly and aphid control in cotton. Many questions abound about a new product, especially one that provides new options in whitefly control. Below are some basic facts about Actara (consult the label for specific use information and other restrictions).
While Actara is a new compound for commercial use, UA scientists have been studying thiamethoxam for several years. Several excellent field studies have been conducted in cotton, vegetables and melons in Arizona. In summary, these studies confirm the rather considerable activity on aphids and whiteflies. They also show general safety towards beneficials especially when compared to more conventional products. How does Actara fit in Arizona cotton? What about other insects in cotton? Other Considerations... Rates? Other Considerations... Resistance? Where can I find more information on this or other products of
interest? Some references to learn more about thiamethoxam include: Ellsworth, P.C. 1999. Evaluation of chemical controls of Lygus hesperus in Arizona. In J.C.
