“…Our knowledge of many of these impacts is derived from studies of non-soil dust (mainly limestone dust from cement plants and quarries, and road dust) and their effects on all types of vegetation. However, the harmful effects of high soil dust deposition rates on yields of wheat (Triticum aestivum L.) and cowpea (Vigna unguiculata L.) have been demonstrated in field experiments conducted in Iran (Hatami et al 2017(Hatami et al , 2018, and similar findings reported for grape (Vitis vinifera) yields by Behrouzi et al (2019) and date palms (Phoenix dactylifera L.) by Torahi et al (2021). Dust may also reduce the efficacy of herbicides used on cropland.…”

Sand and dust storms (SDS) are common in the world’s drylands, regions that are also critically important for global food production. Agriculture is the most prevalent land use resulting in anthropogenic SDS sources, resulting in impacts on cropland and rangeland, but food production is also affected by impacts from natural SDS sources. This review assesses our knowledge of SDS impacts on all the major types of food production in terrestrial and oceanic environments, impacts that occur in all three phases of the wind erosion system: during particle entrainment, during transport, and on deposition. These effects are short term and long term, direct and indirect. Wind erosion is a major cause of land degradation and there is good evidence to indicate that the deleterious effects of SDS can reduce food production via substantially diminished yields of crops, pastures and livestock. However, it is also clear that soil dust plays an important role in major biogeochemical cycles – especially phosphorus, nitrogen and iron – with implications for the valuable environmental services provided by numerous ecosystems, both terrestrial and marine. Ultimately, these nutrients have particular significance for soil formation, ecosystem productivity and food webs on land and at sea, and hence the provision of food for human societies. Efforts to mitigate the negative impacts of SDS on the sustainability of agriculture should be balanced with an appreciation of the significance of soil dust to the Earth system.

“…The results clearly showed that control of plants of both weed species ( H. spontaneum and S. arvensis ) exposed to a dust concentration of 1,500 µg/m 3 for an hour was significantly ( p = .001) reduced compared to dust‐free plants (Table 2). Previous field studies confirmed that this dust concentration of 1,500 µg/m 3 can also reduce grain yield of winter wheat and cowpea by up to 35% (Hatami et al , 2017; Hatami et al , 2018). It was also shown that 1,500 µg/m 3 dust reduced photosynthesis rate of S .…”

“…In addition, the dust was applied using an indoor wind tunnel (airflow dust simulator). The airflow dust simulator provides an amount of dust based on the standard unit of µg/m 3 (Hatami et al , 2017), mimicking the airborne dust that occurs as a side effect of global climatic change.…”

Quantifying the detrimental effect of airborne dust on herbicide efficacy

et al. 2020

One side effect of human activity and global climatic change is more airborne dust. This not only has undesirable effects on human health and the environment, but may also adversely affect many agricultural processes, including herbicide efficacy. This is particularly relevant in parts of the world where dust storms are common and limited rainfall means dust persists on plants for protracted periods. Accordingly, a series of greenhouse dose–response pot experiments was carried out to quantify the effect of a dust concentration of 1,500 µg/m3 on the performance of paraquat, glyphosate, sulfosulfuron and 2,4‐D+MCPA. Dust‐treated and untreated seedlings of Hordeum spontaneum and Sinapis arvensis were sprayed with sulfosulfuron and 2,4‐D+MCPA, respectively, while paraquat and glyphosate were applied to both weed species. The efficacy of glyphosate and paraquat decreased significantly in the presence of dust on both species. Similar results were observed for 2,4‐D+MCPA on S. arvensis. In contrast, the efficacy of sulfosulfuron on H. spontaneum was not affected by dust. In the presence of dust, the doses of glyphosate, paraquat and 2,4‐D+MCPA required for a 90% effect were enhanced by a factor of 1.9 to 2.6. The negative impact on glyphosate efficacy was more pronounced in S. arvensis than H. spontaneum, while it was similar for paraquat. Future studies should consider the amount, duration and composition of dust as well as its impact on other weeds and herbicides. Potential approaches to overcome the detrimental influence of dust on the performance of herbicides were also suggested for future studies.
