Attenuation and soil biodegradation of fungicides by using vegetated buffer strips in vineyards during a simulated rainfall–runoff event
(Springer, 2023-06-22)
Article
Open AccessRainfall–runoff events occurring in vineyard fields can result in pesticide ground losses and the subsequent pollution of surface water bodies, derivate from the crop protection spray applications. In this study, the ... -
Advanced spraying systems to improve pesticide saving and reduce spray drift for apple orchards
(Springer Nature, 2023-05-18)
Article
Open AccessNew spraying systems embedded with different technologies have been developed for pesticide application in 3D crops. However, while applied to specific tree crops, the potential spray drift mitigation for advanced spraying ... -
Assessment of map based variable rate strategies for copper reduction in hedge vineyards
(2023-04)
Article
Open AccessReduction of Plant Protection Products (PPP) has become a priority in agriculture, led by European directives and regulations due to the negative impacts and social awareness that pesticides have raised in the population. ... -
Evaluation of an electrostatic spray charge system implemented in three conventional orchard sprayers used on a commercial apple trees plantation
(2023-02)
Article
Restricted access - publisher's policyElectrostatic sprayers can be an option for increasing the effectiveness of treatments and reducing pesticide consumption, but it still requires more verifications, especially in orchards. The spray deposition performances ... -
Occurrence of antibiotics in Lettuce (Lactuca sativa L.) and Radish (Raphanus sativus L.) following organic soil fertilisation under plot-scale conditions: Crop and human health implications
(2022-08)
Article
Open AccessRecent studies have demonstrated the crop uptake of antibiotics (ABs) from soils treated with AB-carrying fertilisers. However, there is a lack of plot-scale studies linking their effects at the agronomic and metabolomic ... -
Combining computer vision and deep learning to classify varieties of Prunus dulcis for the nursery plant industry
(2022-01-09)
Article
Open AccessVarietal control to avoid unwanted varietal mixtures is an important objective for the nursery plant industry. In this study, we have developed and analyzed the capabilities of a computer vision system based on deep learning ... -
Effects of tetracycline, sulfonamide, fluoroquinolone, and lincosamide load in pig slurry on lettuce: Agricultural and human health implications
(2022-12)
Article
Open AccessThe application of pig slurry as fertilizer in agriculture provides nutrients, but it can also contain veterinary medicines, including antibiotic residues (ABs), which can have an ecotoxicological impact on agroecosyste ... -
Key technologies for an orchard variable-rate sprayer: current status and future prospects
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-01-01)
Article
Open AccessAn orchard variable-rate sprayer applies the appropriate amount of plant protection products only where they are needed based on detection data from advanced sensors, a system that has attracted increasing attention. The ... -
Use of ultrasound anemometers to study the influence of air currents generated by a sprayer with an electronic control airflow system on foliar coverage. Effect of droplet size
(2022-11)
Article
Restricted access - publisher's policyAir assistance and droplet’s characteristics influence on the pesticide deposit and its distribution over the intended target during the spray application process. The present research work is focused on the characterization ... -
A new approach for timing post-emergence weed control measures in crops: The use of the differential form of the emergence model
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-11-19)
Article
Open AccessModels based on thermal or hydrothermal time are used to predict the seedling emergence pattern of weeds. These models rely on sigmoidal functions such as Gompertz, Weibull or logistic, in which daily soil temperature and ... -
Characterisation of activation pressure, flowrate and spray angle for hollow-cone nozzles controlled by pulse width modulation
(Elsevier, 2022-06)
Article
Restricted access - publisher's policyPulse width modulation (PWM) solenoid valves are used for controlling flowrates of hollow-cone nozzles on variable-rate air-assisted orchard sprayers. However, little information is available on the spray characteristics ... -
Pesticide dose based on canopy characteristics in apple trees: Reducing environmental risk by reducing the amount of pesticide while maintaining pest and disease control efficacy
(Elsevier, 2022-06-20)
Article
Open AccessAlthough many different designed air-assisted sprayers can be used for pesticide application in apple orchards, the lack of adequate adjustments according to specific crop characteristics leads to application inefficiencies ...
