A MOBILE SYSTEM FOR MEASURING SPRAY COVERAGE - BG1

Acta Horticulturae, 2001
A computerized Spraying Coverage Analysis system has been developed to assist researchers, instructors and farmers to measure the coverage efficiency of pesticide application machines and systems. The system is compact and mobile and intended to work in the field, connected electrically to a tractor, jeep or other agricultural vehicles, or, optionally,

Multiple chromosomes particle swarm optimization-based coverage path planning for complex surfaces spray painting

International Journal of Advanced Robotic Systems
Coverage path planning for complex three-dimensional surfaces spray painting is one of the challenging problems in robotics. In this article, we propose a multiple chromosomes particle swarm optimization approach to address the coverage path planning ...

Effect of drift‐reducing spray configurations on spray deposition and coverage in winter wheat

Pest Management Science
Abstract BACKGROUND Selecting an optimal spray configuration in arable crops is complex due to the large variety in techniques, nozzle types, crop stages, and pathogens.

Physico‐chemical studies on agricultural sprays. VII—The visual assessment of spray coverage

Journal of the Science of Food and Agriculture, 1965
AbstractThe wetting ability of spray formulations is best assessed by a visual examination of the sprayed surfaces, but such a method is open to criticism in terms of observer bias and inaccuracy. By use of a panel of observers, the method has been examined to determine the magnitude of such errors and to find means of minimising them.Inexperienced ...

Sprayed Keratinocytes Suspensions Accelerates Epidermal Coverage in a Porcine Microwound Model

Journal of Burn Care & Rehabilitation, 2000
Keratinocyte suspensions can potentially treat a variety of epidermal defects, but the mechanism of action has not been fully determined. We developed a porcine model to study the effect of sprayed cell suspensions delivered on small wounds within a meshed autograft. Paired full-thickness surgically excised wounds were covered with a fully expanded 3:1

Effect of Air-jet Configuration on Spray Coverage in Vineyards

Biosystems Engineering, 2005
A new type of sprayer developed for orchard is being adapted for vine spraying. The technology uses vertical air sleeves, generating a two-dimensional horizontal air jet, to distribute spray droplets within the canopy. Three different configurations were tested to determine the combination which provides the most appropriate spray distribution within ...

INFLUENCE OF WEATHERING ON DDT COVERAGE IN A POTATO SPRAY PROGRAM

Canadian Journal of Plant Science, 1958
Weathering caused most of the early reduction in deposits of DDT sprayed on potato foliage in experiments at Fredericton, N.B., in 1953 and 1954. During July and August plants in the field lost 26 to 63 per cent of initial DDT deposits within 24 hours after spraying.

Mechanical Factors Affecting Aerial Spray Coverage of Soybeans

Transactions of the ASAE, 1983
ABSTRACT STUDIES were carried out to determine the effects of several factors in achieving maximum aerial spray coverage on soybeans. Test plots were aerially sprayed with benomyl and a fluorescent pigment. The measured fluorescent emission from sprayed leaf samples identified spray application rate and spray nozzle orientation as having the greatest ...

Surface coverage by impact of droplets from a monodisperse spray

Journal of Coatings Technology and Research, 2019
A novel pneumatic monodisperse spray was fabricated to validate the results of a probabilistic model and a stochastic model that were developed to predict surface area coverage of the monodisperse spray. Multiple droplets of a highly viscous 87 wt% aqueous glycerin solution were deposited on a flat, transparent, plexiglass substrate.

Spray Coverage Analysis Using a Hand-held Scanner

Transactions of the ASAE, 1993
Hand-held optical scanners provide a low-cost, portable means of digitizing spray-deposit patterns on water-sensitive and Kromekote spot cards. Software was developed to convert the image data to spot counts, sizes, and coverage information. Measurement errors due to spot size, contrast, and method of selecting intensity threshold were evaluated.
