it can be serologic methods but exactly molecular identifications...

Do you mean detection in a wider context or rather precise diagnostics? My institute (and quite some other research groups) does a lot of research in the field of thermography and hyperspectral imaging for the detection of plant diseases.

Hi Mrs. Weißbrodt ,

I don't know about the thermography and hyperspectral imaging for the detection of plant diseases.I haven't just know...How to use they?

Dear Filiz RZ,

this is a complex field of research, and most of it is still at its very beginnings. There are a number of publications that you might want to check, for example:

L. Chaerle et al. (2003) Physiologia Plantarum 118: 613–619

L. Chaerle et al. (2004) Plant and Cell Physiology 45, 887–96

L. Chaerle et al. (2006) Plant Cell Physiol. 47(9): 1323–1336

L. Chaerle et al. (2011) Nature Biotechnology 17: 813-816

R. Fortes et al. (2015) Precision Agriculture, Volume 16, Issue 4, 441-454

EC Oerke et al. (2011) Precis Agric 12, 699–715

SeA Raza et al. (2015) PLoS ONE 10(4): e0123262.

G. Romano et al. (2011) Computers and Electronics in Agriculture 79: 67–74

This article gives an example of the application of fused sensor data: http://onlinelibrary.wiley.com/doi/10.1111/ppa.12219/full

I am working with thermography for the detection of virus diseases in petunia, but have not yet published my data. 

Dear Sandra Weißbrodt,

Thanks for your advice...It's interesting.

I must know this methods...I will wait for read your study...I wonder that can I apply the method to our viruses...LBVV, MiLBVV, LMV...

Thanks again...

The application of thermography is highly dependent on environmental conditions and plant architecture. Broad leaf lamina are rather easy to measure, narrow leaves such as from grains seem to be problematic. Also, the leaf angle plays an important role, as do properties of the leaf surface (cuticle, leaf hairs etc.). If you have specific questions, I will gladly try to help.
