A friend and I were talking today about viruses encapsulated and non encapsulated regarding birds , I started wondering about it in plants . here is a link to a ( heavy reading ) the article about TMV is interesting . Gin

Wow great link! I am quite shocked by this passage.Quote:
MANAGEMENT
Milk inactivates many viruses - use milk to wash tools/hands. "Milk does a plant body good!" Soap and water work well too!
Removing diseased plants, killing and removing potential virus vectors (primarily weeds and insects).
disease-resistant cultivars.
disease or virus free seed, roots or tubers.
cross protection (inoculation with a less-virulent strain of a virus protects the plant from a more virulent strain later when exposed to it).
heat (some viruses are killed at temperatures that will not kill host). For example, dormant propagative organs dipped in hot water (35 C) for few minutes or hours, or by growing plants in greenhouse at 35-40 C for several days, weeks or months may inactivate virus.

I don't believe that at all , sounds to good to be true lol . gin
lol Hey your link.:evilgrin: It does seam a bit ridiculous. If true we are all practicing a nice brand of "over-kill" hygiene wise.Quote:

This part about using milk says that it seems to help reduce spreading, doesn't say that it cures infected plants:Quote:
* difficult to inactivate, and can survive for 5 years in dead, dried tissues and many months in living plant tissues.
* many strains, that vary in virulence from severe to mild symptoms. virus is spread from plant to plant through injuries caused by crop worker, contaminated equipment and chewing insects.
* virus overwinters in dead plant tissues and debris, on contaminated equipment, in contaminated soil, greenhouse containers, bedding, tools, and in living hosts, including weeds like horsenettle, Solanum carolinense, and other crop plants (tomato, pepper, and eggplant).
So, just personally, I don't think we're going overboard by taking the precautions we normally do. Growers who typically have problems with this "grow dirty;" I've been to nurseries like that--all kinds of junk everywhere, dead leaves and flowers on the benches, on the floor, in corners, plants all falling over and piled on each other, looking like hell--nasty stuff. Those places even look like insect and disease traps, so it's really no surprise when the plants that come out of them have caught something or other.... Lot of work keeping a greenhouse clean, but I think it's totally worth it.Quote:
Management of Tobacco Mosaic Disease
* use virus-free seed (tomato seed can by treated with acid or bleach)
* transplant in noninfested soil
* fumigatation with methyl bromide or heated.
* no chewing of tobacco or smoking around seedbeds or in greenhouses.
* to eliminate spreading of virus wash hand with soap and water or milk.
* spraying plants with milk (whole or skim) seems to help reduce
An excellent read, Gin! I have to ask you, though....does your head ever feel like it's going to burst with all that knowledge trapped inside??? hehe
:aaa: Viruses scare me.
Now I'm more curious than ever about why my Onc. Sweet Sugar's leaves are kinda crispy and curling under....maybe I should give it some milk?:noclue:

Make mine half and half lolol. I wonder if they were referring to acids in milk that would inactivate certain types of viruses ?
On another note I had a Mokara that had a bacterial rot , Was going to throw it out instead injected it with an antibiotic 3 times , it stopped the rot , not supposed to work on plants . Might of been just luck ?
Bugs marinated Oncid. leaves deep fried mmmmm good . Gin
