Remote sensing as a toll for the study of plant diseases on agriculture: a revision

Abstract: Para que estudos epidemiológicos e medidas de controle de doenças de plantas fossem realizados foi necessário o desenvolvimento de métodos de quantificação de doenças. As doenças podem ser avaliadas por métodos diretos ou indiretos e dentre os métodos diretos encontram-se a estimativa dos parâmetros de incidência e severidade e as técnicas de sensoriamento remoto. Em estudos de doenças de plantas, o sensoriamento remoto, além de ser utilizado para quantificação, também poderá servir para a detecção de plantas … Show more

“…It might have happened because the increase of the populational density generated an increase in the levels of the chlorophyllase enzyme, whose function is to degrade this photosynthetic pigment's molecules (FREIRE et al, 2013). The incident light absorption made by plants attacked by phytopathogens undergoes changes in the interval of the visible and infrared region, a fact caused by the reduction in the level of chlorophylls, changes in other pigments, or in the leaf's structure itself (NAUE et al, 2010). In cotton plants (Gossypium hirsutum L.), the chlorophyll levels were directly proportional to the level of the M. incognita inoculum (ABRÃO; MAZZAFERA, 2001), results that are different from the ones hereof.…”

“…Among several techniques of aid for farm crop management, the use of remote sensing has shown promising results for rapid and efficient detection of diseased plants in small and large geographic areas (Naue et al, 2011;Zhang et al, 2019). It is a technology composed of sensors and platforms, capable of obtaining information from the surface without physical contact with it, and often at long distances, from satellites and manned aircraft.…”
