Not 100% sure but it looks like erwinia soft rot. peeps call it the orange rot that kills lophs. Whatever the pathogen name this is very contagious.

killing the scale will not stop the fungal infection. You need to control both. @Glaukus mentioned a few methods in the above comment. You could also buy yates brand lime sulphur from bunnings. this stuff will kill your scale and will slow down or even kill the fungal infection. repeat in 14 days. this product can only be used in winter.

scale yes , fungal yes. not phytophthora though. IMO the scale has caused a fungal attack by damaging the skin.

Could of been scale but the problem is a fungal issue, You need to treat with a good fungicide.

most of this is very good info, I would wait a month in northern nsw to sow, the temps are to high. just sprinkle the seed on the surface, keep moist until they sprout and then back the water off. they grow really well amongst the cactus. they do like a fed during the young stage but they happy to grow without it. po ash is perfect once they flower. I think planthelpers climate would be very tricky to grow this species.

Yes it is very common in Bridgesii species when it's very hot and humid. I can't see any tiny black dots amongst the infected area, which would indicate a fungal issue. so I would say its a nutrient deficiency. Like glaukus mentioned , It a good idea to lay down some dolomite lime. backed up with a good drink of liquid po ash. potassium helps strengthen plants, it thickens their cell walls and defends the plant against disease. Just to be on the safe side I would also give them a spray of a good fungicide because the plant is under stress which can lead to fungal attacks.

All sold for now, thanks

zelly is your tree a yopo or cebil? I thought yopo couldn't handle the frost that well.

Leave it alone, give it a good drink of seasol and powerfeed, Looks like it might be to wet aswell. they are tough as and over caring can knock them around.

The guy hardy speaks english. that's why misplant labels everything as echinopsis. a lot of trichocereus labelled seeds are destroyed now by customs.

I also can help.

I have never seen any mite damage on my trees. I live in the sub tropics were mites are fearless. I am with PH on the white oil thingy. He knows a lot about khat growing and breeding. You are right though about keeping mites in check , They can go wild and cause a world of pain.
