Bt breakdown?
Because it isn't a poison as such, it is a microorganism. Grubs and caterpillars need to get it into their gut by eating it for it to be effective, which is why you put it on to leaves and other parts of the plant that makes up their diet, they don't eat dirt. David That makes some sense. But again, if my soil gets "infected" by Bt with repeated applications, I can stop buying the stuff and just dust the leaves with the infected soil year after year, right? That is, dryness doesn't kill it. Wetness doesn't kill it. So where does it go, once it's in soil? I guess something else in the soil must kill it. Nothing to live on there? Well, I'd say the same thing when it's dissolved in water, but it seems to do just fine that way. Powder and liquid forms of Bt are active, I am told, for years. |

Bt breakdown?
Google "Bacillus Thuringiensis" and persistence; for 35,000 hits Tried that. That's why I'm here. (My fingers are pretty sore ...) |
