Until recently, the stink bug was an incidental pest that did not draw a lot of attention in terms of its effect on tree nuts. This was because stink bugs were largely contained by dormant-season insecticide sprays that accounted for a broad spectrum of nuisance insects.
However, stink bugs have caused an increasing amount of trouble in recent years and require growers to pay them more individual attention than in the past.
There are two main types of stink bugs that affect tree nuts: green soldier bug and red-shouldered stink bug. While most stink bugs congregate in weedy areas or nearby crops and migrate into tree nut crops, the green soldier bug can overwinter inside the orchard.
Stink bugs do the majority of their damage from May-July, when they use their mouthparts to puncture the hull and reach the kernel. Damage can be identified by gumming at the point of entry and by the kernel, which will appear wrinkled and deformed. Stink bug damage usually occurs later in the season than does damage from the leaffooted bug.
An effective treatment program is critical to protecting crops—and yield—from stink bugs and leaffooted bugs. One application of Belay® Insecticide, provides broad spectrum control of many tree nut insects, including stink bug and leaffooted bug. Belay is softer on beneficial insect predators than older chemistries and provides growers with a unique mode of action, making it an excellent and sustainable tool for IPM—always an important consideration for almond growers.
Belay is also more effective against stink bug than other neonicotinoids. Belay is labeled for use post-bloom in almonds. Always follow label directions.
