Abstract: Deposition of ragweed pollen released from a point above a corn crop was directly observed on foliage, and the number of particles deposited was related to the concentration of pollen in the air, the wind within the crop, ...

Abstract: Practical problems in predicting the spread of plant diseases within and between fields require knowledge of the rate of release Q of pathogenic spores into the air. Many plant pathogenic fungus spores are released into ...

Abstract: The extensive adoption of genetically modified crops has led to a need to understand better the dispersal of pollen in the atmosphere because of the potential for unwanted movement of genetic traits via pollen flow in the ...

Abstract: The widespread adoption of genetically modified (GM) crops has led to a need to better understand the atmospheric transport of pollen because of concerns over potential cross-pollination between GM and non-GM crops. Maize ...

Abstract: Cylindrical, platinum-coated, hot-film anemometers were struck with a series of individual drops of water while immersed in controlled airflows with velocities ranging from 0.3 to 5.0 m s?1. Subjecting the sensor to water ...

Abstract: The removal from leaves of small particles such as pollen, dust or spores often requires gusts of wind having speeds that greatly exceed the mean wind speed. To determine the frequency of occurrence of such fast gusts we ...

Abstract: Theoretically, the aerial transport and deposition of fungal spores near to their source dependon the way in which they become airborne. Spores of some fungi are injected into the air, independentof wind speed, whereas ...
