Fungicide spray coverage and deposition in soybean asian rust management

open access: goldBioscience Journal, 2019
At maximum vegetative growth, sprays with fungicide to control Asian rust (Phakopsora pachyrhizi Sydow and P. Sydow) should reach high canopy penetration and plant coverage. Therefore, the central objective of this study was to determine leaf area, spray

Spray coverage analysis of topical sprays formed by cold thermoreversible hydrogels. [PDF]

open access: yesDrug 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 ...

Spray deposition and coverage on nursery trees from precision applications of a laser-guided variable-rate spray system

open access: greenSmart Agricultural Technology
A conventional air-assisted sprayer was retrofitted with a laser-guided variable-rate spray control system, allowing operation in either constant-rate mode (CRM) or variable-rate mode (VRM) to improve spray efficiency.

'We spray and walk away': wall modifications decrease the impact of indoor residual spray campaigns through reductions in post-spray coverage. [PDF]

open access: yesMalar 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.

Reported community-level indoor residual spray coverage from two-stage cluster surveys in sub-Saharan Africa [PDF]

open access: yesMalaria Journal, 2017
Background Malaria is an important cause of morbidity and mortality in malaria-endemic areas. Indoor residual spray is an effective intervention to control malaria, but high community-level coverage is needed to maximize its impact.

Coverage of the Sprayed Objects in the Aspect of the Coefficient of the Spray Surfaces [PDF]

open access: yesActa 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.

Leaves coverage of spray liquid and influence on herbicide efficacy [PDF]

open access: diamondActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
The effect of spray liquid leaves coverage on efficacy of herbicides was investigated. Five nozzles sizes were used to reach different percentage coverage. The effect of leaves coverage on Elytrigia repens (L.) Desv. was evaluated using systemic herbicide (clethodim 240 g / l + surfactant) and the effect of leaves coverage on Chenopodium album L.
