Early pathogen detection under different water status and the assessment of spray application in vineyards through the use of thermal imagery 总被引:3,自引:0,他引:3

Remote detection using thermal imagery has potential for use in the pre-symptomatic diagnosis of abiotic stress or of early
disease detection. The latter is an issue of great importance since late detection of fungus attacks or poor spray coverage
are major factors contributing to weak disease control affecting fruit quality or reducing yield in grapes. In greenhouse
experiments the effects on spatial and temporal variability of leaf temperature of grapevine (Vitis vinifera L. cv. Riesling) leaves inoculated with a fungal pathogen (Plasmopara viticola (Berk. & Curt. Ex de Bary) were studied in either well-irrigated or non-irrigated potted plants. Due to the high sensitivity
of leaf temperature to the amount of water transpired, infra-red thermography can be used to monitor irregularities in temperature
at an early stage of pathogen development. Evidence for characteristic thermal responses in grapevines was apparent well before
visible symptoms appeared. Contrasting thermal effects due to the pathogen attack were found between measurements on well-irrigated
and water-stressed plants. Furthermore, from a technical point of view, thermal imagery has the potential to assess the evenness
of spray coverage within a canopy, hence optimizing pesticide application efficiency. 相似文献

Samples of 79 black paints from 27 manufacturers in the United States were examined to determine the extent to which paints can be distinguished by pyrolysis-gas chromatography. Evaluation by a Carbowax column showed some differences among paints from different manufacturers and among batches of paints from the same manufacturer. However, it was not possible to conclude that paints with identical chromatograms had a common origin. 相似文献
