Neonicotinoid seed dressings have caused concern world-wide is reported in the 2017 published articel here in
https://www.researchgate.net/publication/318129140_Country-specific_effects_of_neonicotinoid_pesticides_on_honey_bees_and_wild_bees
I am interested to know if seed dressings with neonicotinoid is really forbidden. A) in which crops and
B) in which countries especially in USA.
Who has a survey what is going on?
Thanks.
Yes: US regulations allow seed dressing and its use.Here in Canada, notably in Quebec and Ontario, there has been a hot debate questioning the usefulness of seed dressing with insecticides because in some regions and crops there is no need to use insecticides when insects are at low levels. Another consideration was that it was less expensive to use insecticide-treated seeds rather than untreated seeds.
Dear Replyers,
thanks for your answers. I ask, as we have a neonics moratorium in AUSTRIA & EU now, and maize is dropping from eaten roots of diabrotica damages and now additionally by gigantic mices multiplying in fields with special biodiversity greening plants.
As I hear USA has a big diabrotica problem, I am asking me, what they do now?
Crop rotation does help well yet, a the diabrotica pest invasion is already so gigantic, that maiz can only planted whare maize never was sowed.
Look at my photos in:

Read the articel of an Austrian extension service adiviser, it is correct?
Diabrotica Control in the USA
In the USA, diabrotica control in the maize belt is nevertheless a difficult undertaking despite crop rotation and large strokes with low marginal effects. With the Southern corn rootworm (MWB), Diabrotica un-decimpunctata, and the green Northern MWB, Diabrotica barberi, two further representatives of this dangerous species occur, even if only subordinated. The Northern MWB shows the peculiarity that it needs two winters before it can hatch and that this pause makes appropriate crop rotations with two years of non corn crop necessary for control.
American farmers still have access to insecticidal stains and a larger selection of granulated insecticides (Aztec/ Cyfluthrin+, Belay/Clothianidin, Capture/Bifenthrin Force/Teflu-
thrin, Counter/Terbufos, Smart-Choice/Chlorethoxyfos+ etc.). In practice, there are also maize varieties with five genetic modifications which, with their independent toxin formation in the entire plant, are also effective against the maize root borer (Agrisure, Hercu-lex, Smartstax, VT Triple Pro etc.). For beetle control, insecticidal active ingredients are also available in individual formulations and numerous mixtures when certain damage thresholds are reached. These include chlorpyrifos, deltamethrin, cypermethrin, per-methrin, cyhalothrin and a few more, which in most cases are not permitted in the EU for beetle control in maize.
The danger of the pest is due to its genetic mutability. In practice, sophisticated resistance management is part of every control. Nevertheless, within a few years MWB managed to develop a resistance management system.
against the various chemical and genetic control approaches. In the refinement areas, corn rootworm pressure has increased in recent years to such an extent that in regions with low crop rotation, insecticide dressings and seed granules are applied and used by farmers together with genetically modified varieties.
Overall, the situation in the United States is that, despite the large number of chemical and genetic control options available, farmers are once again having to rely increasingly on crop rotation to contain the corn rootworm. This applies in particular to areas that in recent years have increasingly relied on maize cultivation for processing, but also for ethanol production.

We are in a debate about neonicotinoids in USA and Canada.
See attached pdf to give you an idea.

I Agree with Charles Vincent reply : US regulations allow seed dressing.
Neo-nicotinoid seed dressing in the United States of America is allowed with proper concentration so that insects will not damage seeds.
