Field corn has become a more prominent crop in the Mid-South, so the number of cotton-corn interfaces has greatly increased over the last several years.  A common observation of these corn-cotton interfaces is that tarnished plant bug damage to cotton plants is often more severe in areas adjacent to corn fields than to cotton plants farther from this interface.  Also, there is evidence that TPB abundance is naturally higher at this edge.  If corn is a major source of TPB that infest cotton, it may be possible to reduce TPB damage throughout the cotton field by treating only the field border immediately adjacent to the corn field.  Even if overall TPB suppression is not realized, localized treatments to the cotton field border may increase yields in these areas enough to justify this extra cost.  This project was conducted to examine the impact of side-dress applications of Temik 15G along corn-cotton interfaces on TPB density, crop damage and cotton yield.
