Well, I'm assuming bud rot can ruin your whole crop. I know you don't want to smoke moldy bud (unless we refine the molding, like we did to make cheese). As for the bugs themselves, the pix I've seen show them really buried DEEP into the buds, a fucking mess to my eyes. I seem to recall one fellow saying that he fumigated with sulfur (like they used to do in the old days), and it STILL didn't get them all! That shit is NOXIOUS, too.
So, I like going organic whenever I can, especially if it's something I'm going to eat or smoke. To that end, because of my experiences this summer, I LOVELOVELOVE tobacco tea, even better than pyrethrin.
Basic recipe (to be sprayed on all surfaces of plant and soil, not to be disposed of where it can get into waterways).
- 10 grams loose leaf tobacco (I like Bali Shag or American Spirit because I know they're organic and additive-free)
- 1 liter water
- Few drops or flakes of soap
Now, you can either use very hot water, drop in the tobacco and let it steep overnight, or you can put all in a pot and place over VERY LOW heat. You don't even want it to simmer, so if your stove can't do below a simmer, put the pot into another one or put it on the very edge of the burner. Steep like that til the tobacco loses most of its color, turns tan.
Cool that mixture, and add a few drops of non-antibacterial/antimicrobial soap, Ivory or anything that doesn't say it kills germs. This is to help the tea spread onto the leaves and all surfaces, and it also keeps it from stinking like an ashtray.
If this mixture is not strong enough, up the dosage; 12.5 grams tobacco, 15 grams, all per liter of water.
If you don't smoke ciggies, or even especially if you do, try not to get this on your skin. Don't let any pets or animals near it, especially not drink it (it may well kill them), and please heed the waterway warning. This shit is POTENT. The only thing it doesn't quite kill outright are leafminers. Fortunately, I actually don't have a whole lot of pests up here, what with all the meat bees, hornets, wasps and ants that keep everything in check. Oh, and the praying mantises, too. Lots and lots lately.
Oh yeah, and once it's made/mixed, it's not like other pesticides that you have to use up within a certain period of time (like Neem).
Best of luck!
