In case you have not noticed, corn is drying down very fast. As this corn dries down, stink bugs are moving from corn into cotton and soybean fields. Stink bugs are very destructive insects and can cause a lot of problems in a short amount of time. When do we want to terminate stink bug control efforts in cotton? The decision to terminate insect controls can be challenging in some fields, but a few basic considerations will assist you in this decision. When evaluating a field, a grower must first identify the last boll population which will significantly contribute to yield. Once the last boll population is determined, boll development or approximate boll age should be estimated. Depending on the insect pest, bolls are relatively safe (never immune) from attack at varying stages of boll development.

The table below lists approximate boll age in days which bolls should be protected for selected insect pests. During early fall when temperatures moderate, plant development slows down due to cool temperatures and subsequent boll age values will increase. It is assumed that the field is relatively insect-pest free when the decision to terminate insecticide application for a pest is made.

Midville Field Day/Grand

Re-Opening

The annual Midville Field Day will be held on August 20, with registration starting at 9:00 a.m. The field day will consist of plot tours, followed by a catered lunch. Also, this year, a Grand Re-opening Ceremony will follow lunch.
