SEVERAL ORCHIDS WITH BUGS? BLACK SPOTS? FUNGUS?

[jzvegas]

I HAVE ATTACHED THE BEST PICTURES I COULD. THE BLACK THING I TOOK OFF MY ORCHID LEAF MANY TIMES. I AM USING (FROM HOME DEPOT) ORGANACIDE, WHICH SAYS IT IS FOR INSECTS AND DISEASE, BUT NOTHING SEEMS TO CHANGE. I LIVE IN ORLANDO SO WE HAVE HAD HOT SPELLS AND NOW THE RAIN EVERY DAY. THESE ARE LOCATED OUT IN MY SCREENED POOL AREA. ANY SUGGESTIONS?

I'll leave the other pictures for someone else to diagnose, but the black thing in the first photo that you said you took off your orchid leaf many times is lizard crap. Also living in Florida I would recognize it anywhere as it ends up all over my porch all of the time too.

Given the weather conditions, I'd treat with a general fungicide like Cleary 3336.
Neem oil might help with the bugs but you have to watch using that in this heat! Safer soap might be a better choice until it cools down.
The one oncidium type plant in pic two looks pretty rough; I'd take a look at the roots, treat with the Cleary 3336 and repot.

Never saw that coming!

Welcome to OB! Lizard crap sounds reasonable, not that we have them here in NY. The second picture looks like mechanical damage, but not sure about what seems like white oval marks--if they move they could be aphids or something, but if you are using insect spray I doubt that would be the case. I think the chid in third picture maybe has rot problems, the pbulbs are shriveling and look like some are rotting. Have you re-potted recently? I would definitely check the roots to see if there is root and pbulb rot. No idea about the last 2 pictures.
