“…Geometrical canopy characteristics are also important in order to optimize the spray volume in pesticides application [41,42]. Different dosing models are proposed to calculate the optimal amount of pesticide to be applied, including the Crown Height model (CHT model), the Surface Orchard model (SO model) and the Tree Row Volume model (TRV model) [43]. In this regard, the ability of UAVs in easily providing these canopy features could positively contribute to reducing the environmental impact of pesticide applications.…”

Remote sensing techniques based on images acquired from unmanned aerial vehicles (UAVs) could represent an effective tool to speed up the data acquisition process in phenotyping trials and, consequently, to reduce the time and cost of the field work. In this study, we assessed the ability of a UAV equipped with RGB-NIR cameras in highlighting differences in geometrical and spectral canopy characteristics between eight olive cultivars planted at different planting distances in a hedgerow olive orchard. The relationships between measured and estimated canopy height, projected canopy area and canopy volume were linear regardless of the different cultivars and planting distances (RMSE of 0.12 m, 0.44 m2 and 0.68 m3, respectively). A good relationship (R2 = 0.95) was found between the pruning mass material weighted on the ground and its volume estimated by aerial images. NDVI measured in February 2019 was related to fruit yield per tree measured in November 2018, whereas no relationships were observed with the fruit yield measured in November 2019 due to abiotic and biotic stresses that occurred before harvest. These results confirm the reliability of UAV imagery and structure from motion techniques in estimating the olive geometrical canopy characteristics and suggest further potential applications of UAVs in early discrimination of yield efficiency between different cultivars and in estimating the pruning material volume.

“…Ideally these indicators, which have both been used for dose adjustment and dose expression (Llorens et al, 2010;Walklate et al, 2011), should also incorporate information related to canopy density/porosity for still more accurate dose management (Pergher and Petris, 2008). However, when these vegetative indicators are manually determined, there is still a possibility that the canopy structure metric is over-or under-estimated (Rüegg et al, 2001). Predictive modelling and real-time observation of spray deposition patterns are capable of providing a feed-back mechanism to correct misapplications (either over or under applications) (Saddem et al, 2017).…”

“…Scientific studies examining the deposit of products on the targeted crop area have led to the development of various models in use in some countries, (Rueegg et al ., , ) and trials carried out for the biological dossier in these countries are based on these models. To allow better exchange of data between countries, to avoid unnecessary repetition of trials and to prevent residue problems between countries, dose expression should be harmonized in trial reports.…”

Dose expression for plant protection products

2012

EPPO Bulletin

View full text Add to dashboard Cite

Specific scope This standard defines how the dose of plant protection products is expressed and describes the parameters, specific to the site and type of application, which should be recorded so that the dose can be determined in a standard way whatever the crop or product, or the equipment used for treatment. Included in the standard is a description of dose expression methods in three‐dimensional crops (aerial parts of plants in commercial orchards (e.g. pome fruit, stone fruit), hop gardens and vineyards, small fruit and cane fruit crops (e.g. blueberries, gooseberries, raspberries), taller, isolated fruit trees and other high‐growing crops such as fruiting vegetables both in the open field and under protected cultivation) and methods for converting between different dose expression terms. Specific approval and amendment First approved in 2005–09. Revision approved in 2012–09.
