Underneath the brown/tan skin the flesh is healthy and green. I'm going to spray on a weekly basis. The handful of uninfected cacti have been moved as far away as possible. I really do not have anything to lose if it kills the cacti or does not work..seeing that they are in jeopardy anyways. Ill post up what I'm spraying, it targets a wide variety of bacteria, algae, and fungus. I'm sure it will kill good bacteria in the soil so I'll have to take care of that once all is said and done. If the fungus does not die I'll destroy all my crop, dispose or sterilize the soil and disinfect the pots. Then start over with cuttings and a few hundred seeds. I have the works of a large green house shaping up, large enough to house hundreds of my green friends and start veggies earlier in the spring.

That is a wise plan. But bear in mind that any product that claims to target bacteria, fungi and algae is, at best, ineffective. At worst, it will kill your plants too.

Good stuff that everyone else has suggested, but I wanted to say, give you plants plenty of room wherever they're at, don't crowd them together. That way if one plant gets some funky funk of some type, they all wont go down.
I try to mix my cacti in with my other leafy plants, and not have them all lumped together, give plenty of room between plants for airflow.

Tragic. Why God, why!

I'm using Consan triple action 20. I'll let yall know how it goes. Despite the plague most are still growing very healthy up top and even sending out new pups. Planted about 50 sago palm seeds not long ago, most are rooted and/or sending up growth. The 60 aloe plants I transplanted are booming as usual. I'll have a ton of canary island date palm seeds to plant soon.

this seems to be either the typical (propably symbiotic) bacterium that lives within many clones of trichocerei but also cerei, which is also very common with bridgesii (in fact most reports say it hits bridgesii harder than otehr species)
or a pest-insect like I am having from time to time, but it prefers tips and not older growth. I dont think its spider mite.
if this think happened within few days and aggrevated by lots of rain, its proably it.. the bacterium, often called "black rot"
Didn't you see black spots, sometimes oozing with a black liquid before they became tan?
If I am right, it cant be healed, you only have to protect it from wetness during the crisis, and perhaps apply something fungicide in an extreme case, but I never had a reel bad infection

LSoares said: Applying a cure for everything that may be is a sure recipe for disaster, now or in the near future. When a disease hits that hard, seldom will a single application of a remedy solve the problem - what are you going to do, keep applying insecticides, fungicides, miticides, etc. until everything clears? You'll be creating a whole new set of problems for you and your neighbours.
First things first: isolate the affected plants from the general population. You don't want it spreading around, and if it turns out you can't fight and plants will die ([sh]it happens), at least you will have salvaged something.
Second, decide on a possible cause and treat for it. Do you and your friend think fungal? Good, go for it. But remember that when you say "a fungus did this" is more or less the same as saying "an animal did this" - it could be a mouse, a worm, a mite or an insect. Each organism has a very specific sensitivity, and fungi are no different. Try taking a plant or some pictures to a specialized agricultural supplies shop and talk to the guy in charge of the chemicals, maybe he knows of a "broad spectrum" product you can use. If it is fungal, you may have to try a good number of products before you hit the right one (supposing you ever will).
If it was me, I'd probably destroy (read: burn) the affected plants and improve growing conditions. If some days of rain bring an outburst such as this to your collection, you are missing on sheltering and ventilation. Eventually think about spacing the plants apart, to minimize contagion possibility.
I'm sorry if I sound harsh and bring no good news, but sometimes you have to sacrifice a part of your collection to save the rest.
Good luck.
(have you cut through an affected stem? Is it exclusively superficial or has it spread into the core of the plants?)
This is all excellent advice based around the scientific method. The EG needs more posters like you good sir.

Definitely not black rot..I've seen that and heals up fast. It has been slowly happening and just recently exploded. The cactus king guy has been growing/selling cacti since 83'...he has many many many 1,000's(10,000+ or close to it) of all different species. Definitely sounded (looked) like he knew what he was talking about/doing.
