Coverage of the Sprayed Objects in the Aspect of the Coefficient of the Spray Surfaces [PDF]
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2018 The aim of the study was to compare the degree of coverage of the sprayed objects with the selected nozzles in the aspect of the characteristics of the sprayed object, determined by the coefficient of the position of the sprayed surfaces.

Spray coverage on strawberries
California Agriculture, 1988 Complete underleaf spray coverage is essential for good control of several pest problems in strawberries. Two-spotted mites (Tetranychus urticae), for example, tend to build up on the undersides of the lowest leaves.

Spray coverage analysis of topical sprays formed by cold thermoreversible hydrogels. [PDF]
Drug Dev Ind Pharm, 2023 Sprayable hydrogel formulations are promising topical treatments for skin wounds due to their ability to reduce application pain, prolong drug release, and provide moisture to promote skin healing. These viscoelastic materials, however, present challenges in spray ability which can be overcome using a thermoreversible hydrogels sprayed as lower ...

Use of spray target cards and leaf analysis to measure spray coverage
California Agriculture, 1973 This report evaluates a method used to determine the uniformity of spray coverage in a pear fireblight control experiment in 1972. Trees used for the experiment were mature 14-year-olds in a hedgerow planting at 11 hy 22 ft spacing.

'We spray and walk away': wall modifications decrease the impact of indoor residual spray campaigns through reductions in post-spray coverage. [PDF]
Malar J, 2020 AbstractMalaria prevalence has significantly reduced since 2000, largely due to the scale-up of vector control interventions, mainly indoor residual spraying (IRS) and long-lasting insecticide-treated nets (LLINs). Given their success, these tools remain the frontline interventions in the fight against malaria.

Performance of Drift-Reducing Nozzles in Controlling Small Weed Seedlings with Contact Herbicides
Agronomy, 2023 In many EU countries, spray applications should comply with increasingly stringent requirements regarding the drift reduction class of spray nozzles. Many farmers fear that the use of drift-reducing nozzles producing coarse droplet spectra may compromise
