Influence of Spray Volume on Spray Deposition and Coverage within Nursery Trees [PDF]
Journal of Environmental Horticulture, 2008 Abstract Information on better utilizing airblast sprayers to achieve high pesticide spray application efficiency in nursery tree production is needed. Foliar spray deposition and coverage at different heights inside crabapple tree canopies were investigated for a conventional airblast sprayer operating at four different application rates ...

Validating Spray Coverage Rate Using Liquid Mass on a Spray Card
Transactions of the ASABE, 2018 Abstract. Validation of agricultural sprayers is important for quantifying as-applied coverage rates under field conditions. The complexity of modern sprayer control systems presents a challenge for precise field validation due to the use of nozzle control technologies, such as pulse width modulation, to meter chemical flow rates at individual nozzles.

The Effect of Sample Height on Spray Coverage in Mature Pecan Trees [PDF]
Plant Disease, 2015 Pecan scab (caused by Fusicladium effusum) is the most damaging disease of pecan in the southeastern United States. Large air-blast sprayers for orchards are used to apply fungicide to control the disease but little quantitative information exists on the spray coverage achieved in the canopy of these trees.

Modeling and Prediction of the Uniformity of Spray Liquid Coverage from Flat Fan Spray Nozzles [PDF]
Sustainability, 2019 The effectiveness and quality of agricultural spraying largely depends on the technical efficiency of the nozzles installed in agricultural sprayers. The uniform spraying of plants results in a decrease in the amount of pesticides used in agricultural production and affects environmental safety.
