Tracer is probably our last line of defense against Lepidoptera in conventional cotton. Mixtures of the Op's and Carbamates will help hold the line. Boll weevils numbers in traps removed from cotton fields are up this week, while those traps close to fields are still fairly low. This says to me that weevils are bypassing traps for cotton when there is a choice. Diapause treatments therefore become increasingly important.
Field scouting for punctures and for weevils in blooms is very important.
Let's keep the pressure on and knock this pest out once and for all. Whiteflies are increasing in most fields. Honeydew is beginning to build in many of these fields and will cause some problems. It will take at least 2 applications of insecticide to get them back to low levels. Montior at 0.25, Orthene at 0.5 are the materials of choice.
