Overall, my Sacred Cornplanter rustica has suffered the most from insects eating holes into the leaves. This surprised me, since I expected it to have knockout levels of nicotine. Today, I discovered a conclave of earwigs feasting on the young, tender leaves at the top of the plant (the silvery one on the left, photo on the previous page). They seem to stay away from the older leaf, but by then, the little holes become big holes.
Cornplanter is a noticeably viscid (sticky) plant, compared to the tabacums. Despite this, my suspicion is that the high rustica nicotine levels are minimal in the youngest leaf. Another possibility is that the top of this stocky plant is so close to the ground that the earwigs can't help but find the young leaf. (But earwigs seem to climb pretty high everywhere else, like up the wall, into the rafters, and out onto the leaf-hanging ropes in my shed.)
I'm hesitant to put out diatomaceous earth after the smokable leaf has developed. Even though, like President Clinton, I don't inhale, I still don't want that DE floating around in the air. So I'll probably just accept some moon craters in the Cornplanter.
As an aside, the Cornplanter doesn't smell like cat shit yet (maybe when its blossoms open), but it does have a distinctly off aroma as it grows. This comes along with the moistness onto my fingers when I touch it, which is a frequent occurrence due to my desire to remove all of its aggressive suckers.
At this point in the season, Sacred Cornplanter has been nominated as most likely to be voted off the island. (It's really only there for the Mt. Pima / Papante crossing trials.)

EDIT: Today I placed Agribon-AG15 bud bags on four plants (Samsun Maden, Little Yellow, Glessnor and WI Seedleaf).
