| Abstract | Wheat streak mosaic virus (WSMV) is the most common cereal grain virus in the Great Plains and current controls for the disease rely on cultural methods. There are no chemical treatments available for the WSMV vector, the wheat curl mite (WCM, Aceria tosichella Keifer). These experiments tested carbamate, organophosphate, pyrethroid, neonicotinoid, biological control, oil, ovicide, mite growth inhibitor, and soap treatments for potential to decrease WCM population growth on spring wheat (cv. Choteau). Treatment with the active ingredients aldicarb and chlorpyrifos decreased greenhouse WCM population growth rates compared to untreated controls (p˂0.001 and p˂0.001, respectively). Aldicarb is no longer registered for use, whereas chlorpyrifos shows potential for WCM chemical control. Field trials included spring wheat in 2013 and winter wheat in 2013-2014 testing organophosphate, pyrethroid, oil, soap, and mite growth inhibitor treatments. WCM incidence was not affected by treatment relative to controls in 2013 spring wheat (p=0.32) and disease presence was too low in the 20132014 winter wheat trial to see a treatment effect (p=0.78). Chlorpyrifos reduces WCM populations and with further study may provide an additional tool for integrated control |
