Cranberry Weevil Research

In field evaluations, we demonstrated that yellow sticky traps baited with the blend of four aggregation pheromone components trapped significantly more cranberry weevil adults than un-baited controls.
Development of pheromone-based monitoring lures is an important step toward spatially-precise management techniques that may lead to significant reduction in the use of pesticides targeted against cranberry weevil in blueberries.

Annual Weed Control in Vineyards

The program for the control of annual weeds in the vineyard should consider the weed free strip under the trellis and the sod middles between the rows separately.

Good weed control eliminates competition, improves air circulation, and fungicide and insecticide coverage.

Good weed control eliminates weed competition, improves air circulation, and fungicide and insecticide spray coverage.


The “Weed Control Season” starts in late fall, after harvest.  The program implemented in the spring depends on what herbicides were applied the previous fall.  If herbicides were applied in late fall, applications can be delayed until later in the spring.  Residual herbicides should be applied in late winter or early spring after the soil is no longer frozen, if no late fall treatment was applied.

Fungicides for Peach Blossom Blight Management

There was a time when a grower only needed to consider the efficacy and price when deciding what fungicide to employ for disease control. However, as companies sought to discover fungicides that were more effective and less toxic to the environment and non-target organisms, the fungicides also became more site-specific. As a result, these newer fungicides were much more prone to resistance development by the pathogen. So, now growers must also consider resistance management along with efficacy and price when deciding what fungicide to apply.

Orchard Sod Weed Control

Managed sod row middles have many advantages, and have been adopted by many tree fruit growers. They provide a firm drive path for spring spraying of insecticides and fungicides, prevent or reduce soil erosion, and improve soil tilth by increasing soil organic matter. Broadleaf weeds in the sod should be controlled. Weeds are alternate hosts for insects diseases, and nematodes, and weeds in bloom can attract natural pollinators into the orchard throughout the spring and summer. Many insecticides warn against use when bloom is present in the orchard.

Stinger Labeled for Apple Orchards

Stinger has been labeled for weed control stone fruit orchards for years, and is now labeled for use in apple orchards. The weeds controlled fall into two botanical plant families, composites and legumes.

Use Stinger to control susceptible weeds in the tree row and sod row middles.
