Measuring Spray Coverage on Soybean Leaves

Transactions of the ASAE, 1981
ABSTRACT A method was developed for using a fluorescent tracer added to fungicide spray to measure spray coverage on soybean leaves. The unique feacture of the method is that analysis is made directly from the leaf surface without distrubing the spray deposit. A statistical cor-relation was made to express the percentage of spray coverage as a function

Spraying Coverage Path Planning for Agriculture Unmanned Aerial Vehicles

2021 26th International Conference on Automation and Computing (ICAC), 2021
Aiming at improving the efficiency of pesticide application from crop spraying unmanned aerial vehicles (UAVs), this paper investigates problems in spray distribution modelling and coverage path planning (CPP). To capture the pattern of spray, the distribution model is constructed by making use of experimental data and the model fitting method.

A Fluorescent Pigment to Measure Spray Coverage

Journal of Economic Entomology, 1970
Spray coverage was determined by measuring emission of visible light from 5/8-inch-diameter areas of fluorescent pigment-sprayed leaves when they were exposed to ultraviolet light in a Turner Huorometer. Plum trees and grapevines were sprayed with air-carrier sprayers traveling at constant speed, air volume, and air velocity.

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 ...
