Recently, high densities of Say Stink Bugs have been reported in Central Arizona. On April 4, Fox News 10 ran a story about “beetles” taking over a Buckeye neighborhood. After a trip to the neighborhood and surrounding areas, we identified them as Say Stink Bug nymphs and concluded that they were coming out of Russian thistle (tumbleweed), which had recently dried down just outside the neighborhood. On April 22, we collected large numbers of Say Stink Bug adults out of a barley field in the Casa Grande area. It is unclear how much damage they cause in small grains; however, they are easily found in wheat and triticale as well. The populations of Say Stink Bug in central Arizona are likely well synchronized this time of year, with most individuals at the same life stage. http://www.myfoxphoenix.com/story/25169473/2014/04/04/beetle-infestation

Cotton:
Long term research at the University of Arizona have found that the Upland and Pima cotton varieties grown in Arizona can be tracked over their growth cycle by the use of several simple measures. Plant mapping is a method of measuring cotton growth and reproductive development. Measurements of height to node ratio, fruit retention and nodes above white flower can be correlated to crop management, and yield estimation. As a reminder, members of the UA Extension Ag Team have produced set of short videos demonstrates basic cotton plant structure and plant mapping procedures.

The hot and dry forecast will ensure high rates of water use in the coming weeks. Water stress at this time of year can reduce plant stature and lead to square abortion. Monitor soil moisture closely and avoid water stress through timely irrigations.
