thiram

One of the early sprays used was Thiram, which proved effective for a time.

Persons with chronic respiratory or skin disease are at increased risk from exposure to thiram.

Some of them contain thiram, which is often recommended as a deterrent for deer browsing.

Another concern was that some of the seeds were coated with the highly toxic fungicides Maxim or thiram.

They repel deer by odor since many of the sprays contain thiram, which is based on coal-tar derivatives.

Those sprays that contain some quantity of thiram have worked well, as have some pepper sprays.

Some of the spray products available include Deer-Away, which contains Thiram, or Chew-Not.

In the United States, pesticides containing thiram are banned in home garden products because most home gardeners do not own adequate protection.

That said, the long-lasting spray-on coatings based on bitter agents like Thiram and Bitrex can be helpful if applied before the deer start browsing.

Most taste repellents contain Thiram, a fungicide, while the odor repellents may contain either a putrescent egg base, tar oil or an ammonium soap.

The Institute of Ecosystem Studies in Millbrook, N.Y., reports that it has had more success this year with repellents based on thiram, a fungicide, than with products based on soap or putrescent eggs.
