I suppose a light spraying might help with whiteflies when they try to take over. Any help would be appreciated.

Why would tobacco tea be bad on skin? Will have to search nicotine now. I am talking about chewing tobacco, not cigarettes. Unless they are putting poisonous additives in chewing tobacco now as well.

I had organophosphate poisoning once due to my own carelessness. It didn't take much on my hands to cause a problem. I get buggy thinking about using them.

gardenweb!

Will try to add a link

no one loves their plants more than cannabis growers. i'd expect it's now the most academically researched plant in existence. there's a proportionate volume of bunk to wade through, but a champion cannabis gardener has years of fast turnaround to form their erudition and may well have a more informed eye for eg. nutrient deficiencies than a champion rose gardener.

nowadays almost any horticulturally related search will result in mj sites or papers in the top ten. if you search frequently you'll probably get a feel for which sites tend to attract the more scholarly members (although some of them block their pages from google).

since i don't have access to cigarettes, my pesticides are either dishsoap/garlic/pepper/isopropyl infusions, or occasionally dried lavender heads or lavender oil (use with caution, it's quite effective). i'm finding true cinnamon effective for deterring pests as well.

tobacco teas are a traditional remedy, listed in every houseplant care tome i have. if you have the inclination and ability, i'd suggest buying some seed off ebay instead of funding the corps :)

I have found a lot of other options but may add a little tobacco juice (not from cigarettes, too many chemicals) from pipe tobacco to the rest of the arsenal.

I did develop a great spray for working in the yard. The $%&#@ flies and other little things that bite drive me crazy. And I smell good!

Grow my own tobacco. I think I'll try that. Might be interesting.
