Abstract:
In recent years, especially in Italy, France and Germany, the dust detached
during the vacuum seeding from the maize seeds coating (and that of some other crop)based on neonicotinoids caused a wide bee devastation, due to their very high neurotoxicity.
The dust had a fallout on vegetation along the field borders; bees fly on to
grass and flowers to gather nectar, pollen and morning dew and become poisoned, going basically mad and become lost. Among the different solutions proposed, one of them was
to redirect the air flow coming out of the seeder fan towards the soil surface, in order to limit the dust dispersion. A further improvement was to divide the flow into two parts, by
creating a “dual-pipe deflector”, in order to decrease the air velocity, and so to reduce its turbulence.
Unfortunately, this solution was found to have a poor result and leading to the
adoption of filters. Paper filters seem to be an effective solution, but the right type in terms of density must
be accurately selected; moreover, once worn-out, the filters have to be suitably disposed.
Based on these findings, water filters seems to be an adequate solution, because they do not require disposal and the effluent material, adequately
diluted, could be used in the soil as a pesticide, avoiding any dispersion into the air.
Collaboration with the vacuum seeders
manufacturers have enabled the elaboration of suitable solutions
and are presently being researched
under study.
