Safe pest controls

Are sulfur/pyrethrins based products safe to use on our orchids? I purchased an "insect, disease & mite control" from Bayer Advanced called Natria that is supposed to kill fungus, insects & mites, as well as help prevent black spot & rust, which I'm hoping is safe for use. I'm also wondering if it can be applied to their flowers & buds w/o damaging them.
Any help &/or information is greatly appreciated.

Thanks,
-dbroome

I am a complete newbie to orchids so take my answer for what it is worth. Probably not much. I was at the J & L sale yesterday and was watching orchid club members repotting orchids and they used the Nutria product from Bayer on an orchid that I think had scale.
Hopefully someone with more knowledge will weigh in with more dependable information.

Hi while I have not used it, seems ok for rose fungal control, so can see now problems with using it on orchids.
Now depends on what type of orchids you are going to use it on.
Fungal problems usually relate to poor air circulation and this can be improved easily.

I have used both on my orchids, without problems...if a spray, I do it before the lights come on. If I am using sulfur it is a powder usually. I don't spray on the blooms though. If something is on the bud or bloom, I just use a moistened q-tip to remove the offender.

Yea, I've got some rot on new growths of my Zygo from getting water down the leaves while watering or from rain while outside & just cinnamon isn't doing it. It's definitely not air circulation as I'm summering my chids outside & live directly on the Boston Harbor (we've got wind ). I also have the occasional mealy bug & am acquiring more plants recently (busted, I'm addicted) that I try to treat before admitting into general population. Probably a little overkill on the part of this newbie. Just want to make sure I'm not jumping out of the frying pan into the fire by using this stuff if you know what I mean.

Thanks, I'm off to peruse pics & drool over must haves :P

Always a good idea to treat at the first sign

On no Carter! Watch out for those crazy "aunts"! Don't let them pinch the checks of your orchids! LOL...

Seriously though, ants can be a problem.

I'd suggest buying an ant killer that includes a liquid that you put on a small piece of paper in their trail. They will eat it up once they discover it and take it back to their nest where it will slowly release and kill the nest.

When you water the orchid, do you see them crawling out with eggs? If so, then they have nested in your pot and you should repot.
