SWD is here and will be placing all susceptible crops at risk of infestation. Learn about the crop host plants and how to spot infestations on the Crops of Concern and Wild Hosts page.
Populations of this insect are sure to increase to astonishing numbers through and into November. It will be important, as the season progresses, to:
- Check harvested fruit for infestation, using a salt flotation method.
- Keep fruit protected with spray programs, starting with highly efficacious insecticides first and foremost.
- Keep exclusion netting in perfect condition, if you have it.
- Practice sanitation to reduce SWD build-up in your local agroecosystem.
- Mow and weed.
- Prune, tie and train to keep an open canopy.
