A Webinar on Organic Management of Spotted-Wing Drosophila

Date: 

March 4, 2020 (Wednesday) at 2:00-3:30pm Eastern

 

Title:

Organic Management of Spotted-Wing Drosophila

 

Description:

Spotted-wing drosophila (SWD) has emerged as a devastating pest of small and stone fruits worldwide. Losses due to SWD can be as high as 100% and have been valued more than $718 million annually in the U.S.  The zero tolerance for SWD in fresh fruit has led conventional growers to make preventative insecticide applications when fruit are ripe.  Organic management of SWD is even more challenging due to the low number of effective OMRI-approved materials and limited understanding on the biology of SWD to translate into non-chemical management tactics.  Our multi-regional team was funded by USDA-NIFA through OREI Award No. 2018-51300-28434 to develop, evaluate and implement systems-based organic management programs for SWD.  This webinar will provide a comprehensive update on organic management of spotted-wing drosophila. It will summarize findings of the research conducted by our project team on organically approved strategies including behavioral, cultural, biological, and chemical tactics to manage SWD.

Disease management recommendations following 2019 freeze damage

Following recent freezes in the Georgia blueberry production region, the threat exists for subsequent damage from fungal pathogens. On tissues already damaged by freezes, two fungal pathogens of particular concern are Botrytis and Botryosphaeria.  In addition, root zone saturation from overhead freeze protection/subsequent rainfall can lead to issues with Phytophthora…

Spotted Wing Drosophila Identification, Monitoring, and Management in Georgia Blueberries

Spotted wing drosophila (SWD), Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is an invasive and economically important pest of many soft-skinned fruits such as blueberries, blackberries, raspberries, strawberries, cherries, and other. Since its first detection in California in 2008, SWD spread rapidly across the United States. It was first found in Georgia…

Monitoring and Management of Thrips in Blueberries

Flower thrips are chronic pests of both southern highbush and rabbiteye blueberries in the southeastern United States. Thrips are minute (1 to 1.3 mm long) insects with slender body and usually yellowish to orange in color. Adults have long thin wings fringed with fine hairs (Figure 1). Females are generally larger than males. Both adults and nymphs have rasping and sucking mouthparts, which are used to extract cell sap from plant tissues.
