Smart orchard sprayer to adjust pesticide dose to canopy characteristics
Salas, Bernat; Ortega, Paula; Berger, Lars T.; Gil Moya, Emilio
Apple scab (Venturia inaequalis) is one of the most endemic diseases that affect apple production worldwide. An accurate management of Plant Protection Products (PPP) together with the use of the latest technologies is one of the objectives of the EU Horizon 2020 OPTIMA project, as part of an integrated pest management (IPM) system.
Optimal dose adjustment of PPP in orchards requires an accurate identification of canopy characteristics and a precise sprayer adjustment to distribute the adequate amount of active ingredient and liquid proportionally to the canopy variations. Furthermore, the possibility to use available tools and knowledge to consider the potential variability inside the parcel will lead into a reduction of the amount of PPP, which is a shared objective with the EU Farm to Fork strategy.
Within the OPTIMA project a smart orchard sprayer has been developed. The system incorporates 6 ultrasonic sensors (three per side) for canopy characterization. A dedicated program developed using python allows the system to calculate canopy width and canopy density along the row. This information, together with the georeferenced location of the sprayer and the actual forward speed is used to activate the six-solenoid proportional motor-valves controlling the six different spray sections. Information about working pressure and consequently the nozzle flow rate is recorded every 1 s in order to generate the actual application map.
The system is based on the adaptation of the Tree Row Volume (TRV) method established by European and Mediterranean Plant Protection Organization (EPPO, 2021) with additional information concerning canopy density. The system is linked with development of EDS (Early Detection System) and DSS (Decision Support System) within the OPTIMA project and the aim at the end of the project will be to link all the three technological developments to achieve a holistic smart sprayer.

New method to increase pesticide deposition: Copper microencapsulation
Ortega Rioja, Paula; Sánchez Sánchez, Elena; Tylkowski, Bartosz; Olkiewicz, Magdalena; Montornes, Josep María; Gil Moya, Emilio
Copper plant protection products have been severely restricted in the EU according to soil and groundwater contamination due to the traditional use as a fungicide, especially in vineyards. This limitation, together with the dependence on copper use for mildew control, places winegrowers in a great disadvantage, especially in organic production. Therefore, EURECAT together with the UPC, have developed a new copper product, more efficient in terms of deposition, in order to reduce the amount of active ingredient necessary for good disease control. Preliminary trials have been carried out by the UPC, in order to select the best formulation and to compare it with a conventional copper-based product in terms of deposition using filter paper as a collector in an artificial vineyard. The obtained results show that deposition of different developed products is statistically different from the control product, even doubling the amount of copper deposited in the collectors, which would be a promising solution to solve the problem outlined above.

Assessment of the influence of the nozzle’s pattern and spray distance on vertical spray profile.
Llop Casamada, Jordi; Biscamps Dalmau, Jordi; Gil Moya, Emilio; Gibert Garcia, Pau; Heinkel, Robert
The European Green Deal strategy pursues the reduction of pesticide use by 50%. Spray
application techniques are one of the key points to accomplish this objective. In bush and
tree crops, the proper adjustment of the sprayer is an option to reduce pesticide losses. On
these crops, vertical spray distribution is a relevant aspect to optimize spray distribution
on the canopy while reducing losses to the environment. Vertical patternators are a suitable
technique to assess liquid distribution. In this study the vertical spray distribution of three
type of nozzles (ATI8003, IDK 9003 and 652-30), at three distances (1, 2.5 and 5 m) from
both sides of the sprayer were assessed. A vertical patternator of 3.5 m high, fitted with 30
collectors was used. Results show a different contour of the liquid profile between nozzles,
distance to target and side of the sprayer, as uniformity values ranged from 70% in best
cases to 19% to worst case. In spite of influence of sprayer side, results of symmetry are
classified good or very good.

Droplet size classifications for hollow-cone nozzles manipulated with two different PWM valves
Salcedo Cidoncha, Ramón; Zhu, Heping; Jeon, Hongyoung; Ozkan, Erdal; Wei, Zhiming; Gil Moya, Emilio
Implementation of PWM-controlled hollow-cone nozzles in orchard sprayers is the optimal solution to achieve variable-rate applications; however, there is still little information on the droplet size distribution and spray quality for these nozzles. Droplet spectra were investigated for hollow-cone nozzles with five flow capacities (D2-DC25, D2-DC45, D4-DC25, D4-DC45, D5-DC25) connected to two different commercial 10 Hz-PWM valves under laboratory conditions. Other variables for the droplet size measurements included three operating pressures (276, 552, 827 kPa) and ten duty cycles (DUCs) ranging from 10% to 100% at 10% intervals. Volumetric diameters (DV0.1, DV0.5, DV0.9) were determined with a particle/droplet image analytical laser system and were used to calculate the overall droplet size distributions. Additional assays were conducted following the ASABE standard S572.3 to classify the corresponding droplet sizes. The classification of droplet sizes based on the ASABE standard illustrated that the same flow capacity nozzle controlled with two different PWM valves generally produced similar droplet spectrum classifications. As a result, the information established from the tests would be implemented in the future precision variable-rate spray system designs using PWM valves. © 2022 ASABE. All Rights Reserved.
