This is good, thank you Surendra for posting this. This problem is confounding quite a few people and I haven't ever seen anything like it. The photo series is interesting, we have one case of a plant declining with some reddening which one might associate with virus infection, yet the next picture is of a plant which is simply not "thrifty" (to use a word I learned from a PCA colleague yesterday) and not showing any discoloration or wilting.  
 
However, the third picture is the one which interests me the most. Here we have two dead plants next to several which are apparently unaffected. This says to me that what is affecting these plants is not very plentiful but of very high impact. If a plant gets it, it dies and if it doesn't, nothing happens. This is different than what I recall from the pallidosis related decline (combined with BPYV) we had in Watsonville in 2003, where plants in the center of the affected area would have the most symptoms and plants towards the outside showed less, meaning that plant response was based on concentration of the malady within it.  
 
Food for thought. Very useful post.

Thanks for your comments, Mark.  
 
Identifying those other viruses is important first to know whether or not this is pallidosis-related decline. I found out that the mechanism of synergy between SPaV or BPYV and other viruses is still under investigation. Since some of these disease are not common, we learn something new with each incidence.
