Over-the-counter pest management products: A bumpy road in the post OP period

In a short period of time there has been a major turnover of arthropod pest management products in the over-the-counter market. The greatest effect has been due to registration restrictions on organophosphate insecticides that previously held heavy market share - primarily chlorpyrifos and diazinon. In response, there has been development of many alternatives, including myriad pyrethroids, spinosad, some IGRs, imidacloprid, and various botanical products. Overall, these new products have been able to replace the pesticides that have had registration restrictions, but there have been some pest issues that have been poorly addressed in this transition. For some this is due to inadequate alternatives, but equally important is inadequate labeling and marketing of effective alternatives. As a result there have been some "bumps" in the transition, such as ability to effectively control certain borers and spider mites. This discssion will review the recent history of over-the-counter insect management products and suggest means of correcting existing gaps in what is needed to optimally manage arthropods in garden and landscape plantings.
