New Consumer Insecticide Products

This article was published originally on 8/11/2000

The Bayer Corporation has announced the introduction of a new line of consumer lawn, garden and home insect control products at major retail outlets around the U.S. The new "Bayer Advanced[TM] Product line" brings to consumers existing insecticide ingredients that have been used by professional applicators for the past several years. I suspect this is the beginning of a new trend as new products are introduced to replace older insecticides that are being discontinued (e.g., Dursban).

The following table lists the products, formulations ingredients and application sites. Most products come in a variety of sizes, as well as the different formulations listed. Active ingredients are discussed below.

The Active Ingredients.

Cyfluthrin is a synthetic pyrethroid insecticide that has both contact and stomach poison action. Available since 1987 and used by commercial applicators under the trade names Baythroid or Aztec (vegetable growers), and Tempo (household pests, turf and ornamentals). Skin and eye irritant in humans. Moderately toxic to mammals, low toxicity to upland game birds and waterfowl, little information available concerning toxicity to songbirds, highly toxic to marine and freshwater organisms, highly toxic to bees.

Disulfoton is a systemic organophosphate insecticide and miticide that is especially effective against sucking insects. This ingredient has long been available under the trade name Di-Syston. Disulfoton is very highly toxic to all mammals by all routes of exposure and products formulated at greater than 2% disulfoton are classified as Restricted Use Pesticides. Bayer Systemic Rose Flower Care is 1% disulfoton. Poisoning will be unlikely if exposure to formulated products is minimized by following label directions: wear rubber gloves, avoid getting in eyes or on skin and avoid breathing dust. Disulfoton is moderately toxic to birds, highly toxic to aquatic organisms, and toxic to bees.

Imidacloprid is a systemic, chloro-nicotinyl insecticide (a relatively new and different chemical class). Other products that contain imidacloprid and their uses include Premise (termites), Admire and Provado (commercial vegetables), Marathon (greenhouse) and Merit (turf and ornamentals). Imidacloprid is moderately toxic to mammals, toxic to upland game birds, has moderately low toxicity to fish, may be very toxic to aquatic invertebrates and is highly toxic to bees.

Trichlorfon is a selective organophosphate insecticide with a long history of diverse uses. Some recent trade names and uses are Dipterex (fly control), Dylox and Proxol (turf and ornamentals). Trichlorfon is moderately toxic to mammals by ingestion or dermal absorption, moderately to highly toxic to birds, very highly toxic to many aquatic species including several freshwater fish, may be toxic to other wildlife, but has a low toxicity to bees.
