Organic Control of Cherry Fruit Fly

The active ingredient spinosad, a microbial insecticide, was tested for efficacy against cherry fruit fly. Several formulations were tested. The GF-120 product, a combination of spinosyn and a feeding attractant, proved very effective. A new system of control using point sources versus complete canopy cover was developed. The use of GF-120, an organically approved material, for cherry fruit fly control has become widespread among cherry producers in the region, both conventional and organic. It is very effective, non-toxic to humans, low impact to beneficials, and low cost due to the low volume used and quick application.

Peshastin Creek Areawide Organic Project

The Peshastin Creek Project was created as a joint effort between the Peshastin Creek Growers Association and the Pear Entomology Lab of the WSU Tree Fruit Research and Extension Center in Wenatchee. The research lab provides a monitoring service for the growers in the valley, to support their efforts toward increased use of environmentally-friendly pest management. Bluebird Fruit has created a special “Gently Grown” label for the fruit produced by the PCG Association. The project compares insect pest management under conventional, ‘soft’, and organic management regimes.
