Insecticides and Replanting Decisions

With wet weather and cool soils affecting corn emergence, some corn growers have decided to replant or are contemplating it. When considering such a decision, make certain you consider the agronomic guidelines. From an insect management perspective, however, it's important to think about the possibilities for applying a soil insecticide during replanting. Many soil insecticide labels have restrictions related to the maximum pounds of a given insecticide that can be applied in one season, which often is the same as the pounds per acre for 30-inch rows. Some labels also suggest that the product can be applied only once per season, whereas others allow for a second application if replanting is necessary. Following are the indications for the most commonly used soil insecticides:

The labels of soil insecticides typically do not prohibit the use of other soil insecticides with different active ingredients if corn is replanted in a field where a soil insecticide was applied during the first planting. There don't seem to be any restrictions for replanting situations with Poncho- or Cruiser-treated seed.--Kevin Steffey
