Below is a summary of the chemical and brand names of the commonly used neonicotinoids. These are toxic to our honey bees. We are asking growers who are using these materials and who are dependent on honey bees for pollination, not to use these products currently until more research is done .
Actara, Platinum, Helix, Cruiser, Adage, Meridian, Centric, Flagship,
Poncho, Titan, Clutch, Belay, Arena, Confidor, Merit, Admire, Ledgend, Pravado,
Encore, Goucho, Premise, Assail, Intruder, Adjust and Calypso (This list was generated by The Senior Extension Associate at Penn State)
Never use a neonicotinoid pesticide on a blooming crop or on blooming weeds if honey bees are present.
• The use of a neonicotinoid pesticide pre-bloom, just before bees are brought onto a crop is not recommended. If one of these materials MUST be used pre-bloom (for example at pink in
apples), select a material that has a lower toxicity to bees (acetamiprid or thiacloprid) and apply
only when bees are not foraging, preferably late evening.
• Do not apply these materials post bloom (example petal fall) until after the bees have been
removed from the crop. For the full report clicke here.
*In the United States, a group of beekeepers from North Dakota is taking Bayer to court after losing thousands of honeybee colonies in 1995, during a period when oilseed rape in the area was treated with imidacloprid. A third of honeybees were killed by what has since been dubbed colony collapse disorder.
*The Dutch government has banned Imidaclprid completely in open-air situations. The product evidently also leaves a residue in the soil that completely destroys the Earthworm population that is so important to soil conservation. It also gets into weeds and other crops grown in the same ground. French beekeepers maintain they have lost thousands of colonies to this pesticide and a sister organo-phosphate called Fibronil produced by Aventis and are calling on the French government to remove both products from the market.
*PARIS - "Gaucho", a broad-spectrum insecticide made by the Germany-based chemical giant Bayer, was banned in France in 1999 due to its toxicity to bees and other forms of life -- including humans -- but its replacement, "Regent", from another German giant, BASF, is just as dangerous say beekeepers and biologists.
