I have read the labels, lol. Since you read the label, you can break down the various coverages between the two, right? What's the re-application rate on the bits? Did the label mention mixing the dunks or the bits in the potting soil? It did mention one. Lifespan of BT?? was that on the label? No it wasn't. Do you think the BT has a different longevity depending on your choice of bits or dunks? It's a bacteria, it doesn't care what it's on. Does the label talk about breaking up the dunks and sprinkling them on the soil?
Basically, the label talks about a quick kill based on broadcasting bits in water, versus the dunks sitting in water. Summit only has one kind of BT but they would like to sell us more than one product, kinda like a 1-2 punch. Hit it with the bits for the quick knock down, then the dunks. That's company-speak..
.it's a bacteria that has a half life of days on the soil surface and a half life of 3-4 months buried. The bacteria never got the memo about the 24-48 hour thing, they are just being bacteria.
