Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide. B. thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies, as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, and flour mills and grain-storage facilities.[1][2] It has also been observed to parasitize other moths such as Cadra calidella—in laboratory experiments working with C. calidella, many of the moths were diseased due to this parasite.[3]

What pests does B.t. control?
B.t. is effective against the larvae, or immature stages, of insects but not the adult stages. There are many strains of B.t., and each is most effective against certain insect pests. Some of the strains include:
  • B.t. var 'aizawa' - for control of larvae of wax moths and other moth species
  • B.t. var 'israelensis' - larvae of mosquitoes, black flies, and other flies
  • B.t. var 'kurstaki' - many types of caterpillars
  • B.t. var 'San Diego' - larvae of elm leaf beetle
  • B.t. var 'tenebrionis' - larvae of elm leaf beetle

Oh wow! A conspiracy theorist! They're everywhere these days.

I asked a question in this forum because it seemed to have more serious members and fewer trolls and bullies than the others I've read. And then you came along.

So, can *you* tell me what's eating my plants? No? And perhaps you can explain just *why* I would make two accounts to comment on my own question? No? Okay then... just checking.

You told the guy his plant looks beautiful and it doesn't look even close to that
Maybe your version of beauty isn't as refined as my palate

He has spammed the whole website with that thing and only you saw a beauty

No conspiracy theory just a true observation

Thats very odd never seen anything like it. Did you pick off the brown parts of the leaves before the picture? Any kind of ipm that may have caused this that your spraying them with before the leaf damage?

There were no brown parts to pick. This is exactly how they grew out. Like I said, it first appeared on an AK-47 and looked the same. It's since affected the Bruce Banner in the photos, a mystery plant from bag seed, and an Old Family Purple. The AK-47 is looking a little better now so hopefully whatever is causing it will just die off.
