Agaves are beautiful and hardy desert plants, that have a conspicuous presence in Arizona landscapes. They are especially valued for their diversity of forms and colors.  Agaves face relatively few pest problems, compared to other landscape plants. The most significant pest is the agave snout weevil, Scyphophorus acupunctatus. Another important, but often overlooked pest is the agave mite or grease mite, Oziella sp. The other tiny bug that scurries around on the agave leaves often goes unnoticed. These minute insects are agave plant bugs. They are easier to detect and cause less damage compared to the other two pests, but can sometimes become a problem.

 

 

Palmer amaranth (careless weed or pigweed) is a plant native to the desert southwest that has developed resistance to multiple herbicide mechanisms of action (MOAs). In multiple crops, in all major Arizona agricultural areas, Palmer amaranth resistant to glyphosate and ALS inhibitors (e.g., Staple®) can be found. A diversity of control tactics are needed to manage herbicide resistant Palmer amaranth.

The Pecan Bud Moth, a species of leaf roller moth, has recently been observed in southeastern Arizona pecan orchards. This is the first time growers have reported this pest and expressed concerns about potential impacts to the crop.

Growers are encouraged to review this information with their pest control advisor to determine what action, if any, is required. 

A mirid plant bug has been observed in high numbers on the catkins of some central Arizona pecan orchards. Multiple growers report this for the first time and have expressed concerns about potential impacts to the crop. This rapid communication is designed to provide the limited knowledge we have about this potential pest. Growers are encouraged to review this information with their pest control advisor to determine what action, if any, is required.
