Spray drift from application of plant protection products with drones in vineyards

Journal für Kulturpflanzen, 2023
Field experiments according to ISO 22866 were conducted to determine the spray drift from Unmanned Aerial Spraying Systems (UASS) applying plant protection products (PPP) in vineyards in order to collect data that can be used for drift risk assessment ...

Predicting Spray Drift from Backpack and UTV Spraying

Transactions of the ASABE, 2018
Abstract. This article summarizes the development and predictions of a Lagrangian-based computer model applied to recent field data on backpack and utility vehicle spraying. Model agreement with data supports the usefulness of the model for the tested conditions, and provides the USDA Forest Service and other agencies with a simple-to-use numerical ...

Mobile robot based electrostatic spray system for controlling pests on cotton plants in Iraq [PDF]

, 2015
A mobile robot based electrostatic spray system was developed to combat pest infestation on cotton plants in Iraq. The system consists of a charged spray nozzle, a CCD camera, a mobile robot (vehicle and arm) and Arduino microcontroller.

Predicting off-site deposition of spray drift from horticultural spraying through porous barriers on soil and plant surfaces [PDF]

, 2005
New Zealand is a recognised leader in horticultural practices which include the use of boundary shelterbelts around orchards. These shelterbelts were primarily established to provide protection to the crop but are also an effective means of ameliorating ...

Experimental study of factors influencing the risk of drift from field sprayers Part 2: Spray application technique. [PDF]

, 2006
Recently, spray drift and its effects have become an important aspect of risk assessment in the registration process of pesticides in Belgium. In this regulation, drift reducing spray application techniques can be used to reduce buffer zones. The purpose

Determining drift in spray tips evaluated under different wind speeds [PDF]

Revista Ciência Agronômica
The application of pesticides is essential in modern agricultural production. The concept of drift refers to the undue displacement of a product, which moves to areas outside the intended target, usually due to air currents.

SPECTRUM, VELOCITY AND DRIFT OF DROPLETS SPRAYED BY NOZZLES WITH AND WITHOUT AIR INDUCTION AND MINERAL OIL [PDF]

Engenharia Agrícola, 2017
The aim of this study was to evaluate the spectrum, the velocity and the potential drift risk of droplets sprayed by nozzles with and without air induction, with the addition of mineral oil to the spray solution.

Sampling, quantification and mathematical modeling in agricultural spray drift: A review

Environment Conservation Journal
An effective spray of agrochemicals is inevitable for crop production for viable agriculture. Spraying inherently suffers from drift, which has always been one of the major concerns in agriculture, affecting the intent of agrochemical spraying and ...

Study of a test methodology to assess potential drift generated by air-assisted sprayers

Journal of Agricultural Engineering, 2013
During pesticide application spray drift may cause diffuse pollution phenomena in the environment. In the last years the European Union, through the Directive on the sustainable use of pesticides (128/2009 EC), has recommended the adoption of measures ...
