“…Works such as those by [87][88][89] suggest that damage to the environment and ecosystems resulting from inappropriate agricultural practices is already present on a massive scale, thereby determining sustainability problems for the agricultural sector in both emerging and developed countries.…”

The agricultural sector of Sinaloa is one of the most representative in Mexico. Its economic and social contributions are of great magnitude, as is its scale of production and the social impacts it generates. The objective was to study the perception of maize farmers in the municipality of Guasave on agricultural public policies and their impact on sustainable results in the sector. The methodology was quantitative-descriptive and cross-sectional. A sample of 260 farmers was analysed out of a study population of 18,650, to whom a survey was applied using the Likert scale. The internal consistency of the instrument was validated using the McDonald omega test, giving a (ω) of 0.868, considered reliable. Kendall’s Tau-c was used to find the relationship between the category and its respective subcategories. The results showed statistically significant correlations (Sig < 5%) that were greater than 0.7, so it was considered that the category “Public policies and sustainable development” showed a strong correlation with the subcategories “Governance and agricultural sustainability” and “Public policies in agriculture”. The results indicate that there is a need for greater attention to public policies, from their design to implementation. Agricultural activity has had a negative impact on a sustainable environment due to the current production methods. It is considered that to achieve significant progress in this sector, studies are needed to help detect and correct these problems and encourage greater participation of the actors in the sector in their work through training and the dissemination of sustainable practices.

“…An active substance is "persistent" if its half-life in water is more than two months and, in soil or sediments, if it is more than six months 10 . The transport of pesticides residue through drift, runoff and leaching can lead to contamination of waters and soils at the basin scale 11 – 15 or global scale, through long-range atmospheric transport phenomena 16 . Indeed, once pesticides are applied to crops, a fraction is intercepted by the foliage and a fraction reach the soil surface 17 .…”

The present work aimed to predict the fate of two pesticides, copper (Cu) and glyphosate in a Mediterranean basin with an intermittent river and to assess the ecotoxicological risk related to their presence in water bodies coupling field measurements of streamflow and pesticide concentrations, and an eco-hydrological model. The Soil and Water Assessment Tool (SWAT) model was calibrated and, subsequently used to assess predicted environmental concentrations of pesticides in surface waters. The ecotoxicological risk related to the presence of Cu and glyphosate in surface water was assessed at the reach scale by using the Toxicity to Exposure Ratio approach (TER). Measurements of glyphosate concentrations (< 0.5 μg l−1) exceeded the maximum European threshold of environmental quality standards for pesticides (EQS) of 0.1 μg l−1. High concentrations of glyphosate were predicted in the wet season and in September, when glyphosate is mostly used in vineyards and olive grove productions. Acute risk (TER < 100) associated with the presence of glyphosate was detected for several reaches. High concentrations of Cu (< 6.5 μg l−1), mainly used as a fungicide in vineyards, were predicted in several river reaches. The results of the ecotoxicological risk assessment revealed that November and January were the critical months during which most of the river reaches showed a chronic risk associated with the presence of Cu.

“…However, a critical aspect of the open-field application of PPPs is that it is rarely constricted to one environmental compartment. Beside the deposition on plants, the PPPs can contaminate nearby fields, surface waters, and soils [11]. Moreover, the average dimension of droplets produced during atomization plays a significant role in the coverage of the target plant, and the smaller the droplets, the more prone they are to be transported away from the target area by air currents, a mechanism known as drift.…”

The use of plant protection products (PPPs) has become fundamental to guarantee excellent field productivity. Nevertheless, their usage presents critical issues, such as the quantity of substances used, the relative toxicity, and the contamination of nearby fields caused by atmospheric drift. This study focuses on the characterization of aerosol droplets of PPPs produced by spraying a chemical marker, fluorescein, with an orchard airblast sprayer equipped with conventional hollow cone (HC) and anti-drift air inclusion (AI) nozzles, using a wind tunnel as a controlled environment. A particle/droplet image analysis was employed to study the droplet production of the nozzles, while a liquid chromatography tandem mass spectrometry (HPLC-MS/MS) analysis allowed us to evaluate samples collected using a cascade impactor located at 5 m, 10 m, and 20 m from the emission point. Overall, HC nozzles are very accurate at producing specific drop size distributions (DSDs), while AI nozzles produce a much wider DSD, concentrating the largest part of the distributed volume into droplets of a larger size. The marker concentration was much lower for the AI nozzles compared to the HC nozzles; moreover, the two nozzles show a similar trend in the coarse droplet range, while significantly differing in the fine droplet spectrum.
