“…In contrast to other devices specifically designed for reducing the dust drift effect, the present kit does not enable 100% dust drift reduction to be achieved. On the other hand, owing to its simple design, it can be marketed at a lower price and requires lower maintenance than other, more sophisticated kits .…”

“…As the pipe outlets were positioned close to the soil (about 0.2 m), at the base of the PVC tank its surface was covered with an appropriate cellulose filtering material (Camfil CM 360) in order to avoid dust dispersion. This material was employed because it had already been successfully used in previous studies to capture dust particles . Weights were determined using a precision balance with a accurancy of 0.01 g (Ohaus® EX10202).…”

“…In recent years, research stations and manufacturers have proposed different solutions to reduce the dust drift effect . Generally, these solutions consist of specific kits for the drills that convey the air exiting the sowing machine fan to the soil, or that are able to filter the exhaust air and to bury the dust particles underground . Nevertheless, manufacturers prefer to use only air conveyor kits because they are easier to install and have low production costs.…”

6BACKGROUND: All maize drills produce a fine dust due to the abrasions of the seed coating that 7 occur inside the seeding element. Nevertheless, the air stream generated by the fan of pneumatic 8 drills -necessary to create a depression in the sowing element of the machine and to guarantee a 9 correct seeds deposition -can blow away the solid particles detached from the seeds. In order to 10 reduce this phenomena, coated maize seeds company (Syngenta®) has set up an ad hoc kit "dual 11 pipe deflector" that easy a fits different pneumatic drills (also old drills). In this study, the efficiency 12 of this kit and the influence of different drills types on the kit effects in reducing the environmental 13 contamination, were evaluated using three different pneumatic seed drills models. 14 RESULTS: The research showed that dual pipe deflector installed on the drill in standard 15 configuration did not change the seeder performance and using this kit on pneumatic drills, 16 independent of their design, it is possible to reduce up to 69% the amount of dust drift with respect 17 to the conventional machine set up. 18 CONCLUSION: Dual pipe deflector, under conditions explained in this experimentation, showed 19 good performances with all types of maize pneumatic drills used. Independent of the seeder model 20 on which is mounted, it is able to obtain similar results highlighting an high operative versatility. 21 22 Keywords: pneumatic drills, dual pipe deflector, maize seed, dust drift 23 24 2 Introduction 1All maize drills produce a fine dust due to the abrasions of the seed coating that occur inside the 2 seeding element. 1 Nevertheless, the air stream generated by the fan of pneumatic drills -necessary 3 to create a depression in the sowing element of the machine and to guarantee a correct seeds 4 deposition -can blow away the solid particles detached from the seeds. 2-3 5On the basis of this situation, some European countries (e.g. Italy) have banned the use of toxic 6 substances in the seed dressing, while other (e.g. France) have required the use of appropriate air 7 conveyors able to address the exhaust air towards the soil. In fact, adopting these kits, it is possible 8 to reduce dust drift and, consequently, to increase the environment safeguard. 4 9During the last years, research stations and manufacturers have proposed different solutions to 10 reduce dust drift effect. 5 Generally, these solutions consist in specific kits for the drills which 11 convey the air exiting from the fan of the sowing machine to the soil 4,6 or which are able to filter 12 the exhaust air and to bury underground the dust particles. 7-9 Nevertheless, manufacturers prefer to 13 use the kit only for conveying air because they are easier to install and have low production costs. 14 All air conveyor kits are mainly composed by three different elements: 1) an air conveyor 15 mounted on the outlet of seeder fan; 2) one or more pipes to convey the air; 3) an air dispersion 16 system positioned close to the soil. 4,6 The main pro...

“…For example, a system that is able to filter the airstream exiting from the seed drill fan by means of air dust separators (sweep-air) 29,30 could minimise dust deposits on the machine frame. Nevertheless, the dust deposited could be reduced by as much as 99% by using a modified seed drill in combination with improved seed coat quality.…”

BACKGROUND: The use of pneumatic drills in maize cultivation causes dispersion in the 7 atmosphere of some harmful substances normally used for dressing maize seeds. Some of the dust 8 particles may be deposited on the machine's body, becoming dangerous for the environment and for 9operators. The aim of the present study was to analyse the amount of dust deposited on the frame of 10 drills during maize sowing operations. Tests were performed with different drills and in different 11 operating conditions. 12 RESULTS: Data analysis showed that a significant amount (up to 30%) of the tracer can be deposited 13 on the drill body. When the wind was not present, higher quantities of tracer were collected and the 14 forward speed did not influence significantly the tracer deposit on the seed drills. The use of 15 different devices that were designed to prevent dust dispersion were able to limit up to 95% but was 16 not able to eliminate the external contamination of the drill. 17

“…Furthermore, these abraded particles pose a serious risk to insects (in particular foraging bees and other pollinators) flying across the field during sowing operations (Girolami et al , 2013Marzaro et al 2011). Since then, attention has been paid to the reduction of particulate matter expulsion using modified drilling machines fitted with devices in order to reduce particulate emissions and proper handling of coated seeds (Biocca et al 2017;Manzone et al 2015;Manzone and Tamagnone 2016;Pochi et al 2015a, b). However, the abrasion potential of seeds still has an important ecological impact without clear benefits in terms of crop yields (Sgolastra et al 2017b;Zwertvaegher et al 2016).…”

With the exponential number of published data on neonicotinoids and fipronil during the last decade, an updated review of literature has been conducted in three parts. The present part focuses on gaps of knowledge that have been addressed after publication of the Worldwide Integrated Assessment (WIA) on systemic insecticides in 2015. More specifically, new data on the mode of action and metabolism of neonicotinoids and fipronil, and their toxicity to invertebrates and vertebrates, were obtained. We included the newly detected synergistic effects and/or interactions of these systemic insecticides with other insecticides, fungicides, herbicides, adjuvants, honeybee viruses, and parasites of honeybees. New studies have also investigated the contamination of all environmental compartments (air and dust, soil, water, sediments, and plants) as well as bees and apicultural products, food and beverages, and the exposure of invertebrates and vertebrates to such contaminants. Finally, we review new publications on remediation of neonicotinoids and fipronil, especially in water systems. Conclusions of the previous WIA in 2015 are reinforced; neonicotinoids and fipronil represent a major threat worldwide for biodiversity, ecosystems, and all the services the latter provide.
