I no longer believe Broad Mites cause DUDDING

Double post

...but here is this:

I can put sap from dud branch onto a wound on tomato to see what it does......though I'm not sure I have anything which is classic duding. If its root rot, I doubt I will see further development.

Hop stunt viroid (HSVd)

In fact, of 200 hop clones tested from the USDA-ARS National Clonal Germplasm Repository (NCGR; Corvallis, OR), 98 entries tested positive for one or more viruses, 50% of which tested positive for AHLV infection and 29% tested positive for ApMV infection, the two viruses that tested positive in the NMSU-ASC Farmington experimental plots (Postman et al., 2005). The USDA-ARS NCGR has since eliminated viruses from most of their Humulus collection through tissue culture methods (Postman et al., 2005).

I was in that lab during the start of the tissue culture program. Did greenhouse maintenance for them.

Also, I've scouted a few dozen hops yards at least 10 times. There are what you could call dud vines on the mound where a vine looks weak with very short nodes and extra branching...sometimes the dud vines are free of disease or insect for the most part.
I've seen at least half a dozen of virus like symptoms out in the fields...nothing gets away from spray too..ever

See the Sterling hop leaf. I know a field with that virus..its most of the field. The grower didn't care and said it does nothing even tough the vines look crappy.

This is something about the PNW and pot growers...the hops industry has established an enormous pool of disease.. PM anywhere around hops is atrocious unless you get a good microclimate and a resistant cultivar. We found PM in Nugget 2 years back. Nugget was grown for decade or better with 0 PM ever. I was in the field with the first documented case of PM on Nugget ever in history.

It may not be coincidental that hops get a stunt viriod. It shortens vines, causes branching/branch dieback, weakens plants, lowers flower weight, lowers essence output, causes lifecycle changes, and has a highly differential expression rate...finally it has low persistence in soil and is sporadically transmitted

The "patent pending clean plant process" in that article sounds like its gonna be expensive.

It's more or less the same in vitro cold therapy that they're using on the viroid in other ag industries (hops, fruit, etc.)

Chrysanthemum stunt viroid (CSVd) can infect Argyranthemum and cause serious economic loss. Low temperature treatment combined with meristem culture has been applied to eradicate viroids from their hosts, but without success in eliminating CSVd from diseased Argyranthemum. The objectives of this work were to investigate (1) the effect of low temperature treatment combined with meristem culture on elimination of CSVd, (2) the effect of low temperature treatment on CSVd distribution pattern in shoot apical meristem (SAM), and (3) CSVd distribution in flowers and stems of two infected Argyranthemum cultivars. After treatment with low temperature combined with meristem tip culture, two CSVd-free plants were found in ‘Border Dark Red’, but none in ‘Yellow Empire’. With the help of in situ hybridization, we found that CSVd distribution patterns in the SAM showed no changes in diseased ‘Yellow Empire’ following 5°C treatment, compared with non-treated plants. However, the CSVd-free area in SAM was enlarged in diseased ‘Border Dark Red’ following prolonged 5°C treatment. Localization of CSVd in the flowers and stems of infected ‘Border Dark Red’ and ‘Yellow Empire’ indicated that seeds could not transmit CSVd in these two cultivars, and CSVd existed in phloem. Results obtained in the study contributed to better understanding of the distribution of CSVd in systemically infected plants and the combination of low temperature treatment and meristem tip culture for production of viroid-free plants.

I was trying to find any correlation between fungal interactions and negative effect on secondary metabolite production.

Found this, seems an interesting read

I wonder if the fusarium / pest collapse interaction can also happen with broad mites, etc.

Could fusarium infections be the domino that falls allowing pests like broad mites and nematodes express like this?

It echos the same thing that happens in ecosystem collapse, one factor gets imbalanced and the rest are effected.

BETA you ever have any personal experience from this problem over the last 7 years? If you did, you'd realize that VIROID symptoms arent the original DUD symptoms...
