Advanced Technologies of Plant Disease Diagnosis

Failure to early diagnosis of plant diseases increases the use of chemical pesticides and reduces the quantity and quality of agricultural products. Rapid, accurate, low cost and early diagnosis of plant diseases, especially those that spread without early symptoms, is effective in reducing the use of chemical pesticides and improving the quantity and quality of agricultural products. In this paper advanced method of plant disease diagnosis based on nanotechnology, nondestructive techniques of spectroscopy and electronic olfaction system is described. Some of these technologies make it possible to diagnose many diseases before the onset of symptoms, which by controlling and preventing the development of the disease, in addition to reducing the cost of disease control, sustainable agricultural, environmental protection and consumer health will also follow.
