The biggest concern right now, according to Goodell, is the possible loss of squares from the phenoxy herbicide drift that is being seen in the valley.

Drift from a pasture application of 2,4-D in Merced County in early June has damaged cotton as far south as Kern County. Officials are still assessing the damage levels. So far, Dan Munk, Fresno County UC cotton farm advisor, said he has not seen any square losses due to the drift. However, UC Merced farm advisor emeritus Bill Weir, has estimated a 15 percent to 20 percent yield loss in fields close to the application.

This, says Goodell, could affect square retention evaluations when assessing a lygus threat.
