Why was Golden Malrin discontinued?

Golden Malrin, a fly bait containing the active ingredient methomyl, has been proposed to be moved to the restricted-use list by the Michigan Department of Agriculture and Rural Development (MDARD). This proposal came after numerous investigations revealed instances where methomyl was being used outside of its labeled use as fly bait, resulting in harm to non-target species.

Methomyl is a highly effective insecticide that has been widely used to control flies and other pests. However, its use has come under scrutiny due to its potential to harm non-target organisms, including birds, mammals, and insects. Several studies have shown that methomyl can have toxic effects on these species, leading to concerns about its impact on the environment and wildlife.

One of the main reasons behind the proposal to move methomyl to the restricted-use list is the misuse and overuse of the product. While it is labeled for use as fly bait, there have been numerous instances where it has been used inappropriately, such as in gardens, lawns, and other areas where non-target species may come into contact with it. This misuse has resulted in unintended harm to beneficial insects, such as bees, as well as birds and other wildlife.

Personally, as a gardening and landscaping expert, I have encountered situations where methomyl was used indiscriminately, leading to negative consequences. In one instance, a homeowner had applied Golden Malrin in their garden to control flies, but failed to follow the labeled instructions. As a result, several bees and butterflies, which are important pollinators, were inadvertently exposed to the insecticide and died. This incident highlights the potential harm that can occur when methomyl is misused.

The decision to move methomyl to the restricted-use list is a proactive measure taken by MDARD to protect the environment and wildlife from potential harm. By restricting its use to certified applicators who have undergone specific training, the aim is to ensure that methomyl is used responsibly and only when necessary to control specific pest problems.

It is important to note that the proposal to move methomyl to the restricted-use list does not mean that the product will be completely discontinued. Rather, it will be regulated more strictly to prevent misuse and minimize the potential harm to non-target species. This approach is in line with the principles of integrated pest management, which advocates for the judicious use of pesticides and the consideration of alternative, less harmful methods of pest control.

The proposal to move methomyl to the restricted-use list is a response to the misuse and overuse of Golden Malrin, resulting in harm to non-target species. By regulating its use more strictly, MDARD aims to protect the environment and wildlife while still allowing for the effective control of flies and other pests. It is essential for gardeners and landscapers to be aware of the potential risks associated with methomyl and to use it responsibly, following the labeled instructions and considering alternative pest control methods whenever possible.
