Spotted Wing Drosophila in Tomatoes
Judson Reid, Extension Vegetable Specialist
Cornell Vegetable Program

What to do?
First, reduce or eliminate over-ripe fruit, or wild brambles in proximity to tomatoes, with extra vigilance for grape/cherry and tunnel plantings. Next, consult the excellent information compiled by the Cornell Fruit Program online. With this information scouting and trapping should then be implemented. Finally, consider protecting crops with effective materials. Note that SWD is not listed on most pesticide labels.
