my question is this- does this pesticide have a residue ? and ...Do you really want to smoke THAT with your tobacco?
Imidacloprid (Admire, Condifor, Gaucho, Premier, Premise, Provado, and Marathon) residue on tobacco 0.9 ppm to 4.1 ppm: https://archive.epa.gov/pesticides/chemicalsearch/chemical/foia/web/pdf/129099/129099-101.pdf
Wikipedia discussion: https://en.wikipedia.org/wiki/Imidacloprid
My impression: Imidacloprid is probably not a human toxicity issue when used on tobacco.Cornell University said:
The environmental concerns (effects of plant imidacloprid residues on pollinators, etc.) are a different matter.

Macho 2. Contains it also.
I was going to spray to kill the jap beetles until I read the label.
I have jap beetles this yr but they are not attacking and eating the leaf as badly like previous yrs.
There might be enough in the plant to repel them like aphids

We are lucky when growing our own to have the choice whether we use these chemicals or not and weigh up the evidence available (bearing in mind the experiments are almost always carried out by the company who wants to sell it to you!) vs the need to save the crop.
I grow tobacco for chewing so I may be more worried about this than most who grow it for smoking.
On the subject of aphids (and many other insect pests) I find this stuff works very effectively and it's definitely non-toxic as some outlets sell food grade versions and advocate eating it as an alternative therapy!

I ended up using 1 Tbsp per gallon of the 1.47% imidacloprid solution and it took me two gallons to water all of my seedlings, which I did three times, a week apart before planting outside. Not sure if my concentration wasn't high enough, or if it's already worn off, but I just noticed aphids on one of my Sumatras yesterday. The last two years I sprayed pyrethrin, but this year I'm going to try a diatomaceous earth dusting as mentioned above, just need to go pick up a sprayer. I have a 10 lb box from when my Great Dane got fleas two years ago.

I'm so glad you posted this. I just went out this morning to my patch and the jap beetles were out on force in the Olor, just feasting . I know how this stuff works , we bought it when we had chickens to dust for mites. I have almost 5 lbs of it I hadn't even opened yet so I put some into what i call a whirlybird fertilizer spreader, you walk ,spin the handle and the trigger activated trap door in the bottom flings out a designated rate. BUT, DE is as fine as flour and it doesn't flow like granules so I ended up just flinging small fingertips worth at the hard shelled tobacco raiders. Die you sonsabitches! Git off my tobacco ! Waiting game now.
Macho , Widow , Admire and other generic admires are to be used at transplant and in transplant watering . It goes under the soil and covered up . The plant takes it up inside for season long protection .
One time application is all that is needed .
When I used to grow a lot of burley acreage , I noticed that at the end of season some aphids would start appearing . Not a lot , but some . This tells me that Admire leaves or is pretty much gone when the plant matures .
Big Tobacco always tested my tobacco at the contract stations . My test have always come back clean with no chemical residue .
Admire and Maleic Hydrazide Was all I used back then .
Admire for Aphids
Maleic Hydrazide For sucker control .

ok, thank you very much for that ...Looks like as much as I'd like to continue my organic growing . Admire will be on my list for the next grow.
The beetles I direct dusted with DE ...the JB's just moved on to other leaves...now theyre on the Criollo ...woe is me.
I did notice though that even though there are aphids in the shade structure , there are no japanese beetles.

It is also used as a foliar spray.
TOBACCO (Foliar Application)
For control of Aphids, apply 1.6 to 3.2 fluid ounces per acre as a broadcast or directed spray to infested area. Use higher rate when insect pressure is heavy.
For control of Flea beetles and Japanese beetle, apply 3.2 fluid ounces per acre as a broadcast or directed spray to infested area.
Foliar Application Notes and Restrictions for Tobacco:
• Pre-Harvest Interval (PHI): 14 days
• Minimum interval between applications: 7 days
• Maximum number of MACHO® 2.0 FL allowed per crop season: 17.9 fluid ounces/Acre (0.28 Ib. a.i./A)
Apply only through properly calibrated ground, aerial or chemigation application equipment insuring thor- ough coverage.

so if I were to find this stuff or the active ingredient no matter the name...you think since I have both aphids and japanese beetles the 3.2 fl oz /acre would take care of my infestation?

I went ahead to Martins supply and ordered a pint of Macho2 . should be here in 2-3 days. as little time as there is left , I think a pint will do me just fine. Just hope the beetles don't invite anymore friends to the dinner table by then.

The pint will last a long time. You will need a about 2 ml. To one gallon of water.
I used the jap beetle traps around the perimeter of the patch to get them in the past.
I really think the macho has been keeping the beetles off of them this yr.

its been years since Ive put out Jap beetle traps . I vowed never to do it again...at least on my own property. Heres why. the pheromone used to bait and draw them in reaches out for miles ,like a bitch in heat (basically and literally). At first ,sure the beetles get off the plants , then its a matter of finding bags to keep up with the carnage. then the bags just start to stink. If I ever put one out again,it'd be in the field 5 blocks away ...with a 30 gallon hefty steel sack at the bottom of it.

Found this bit of info just minutes ago...I believe it fits this thread nicely.

That Virginia Tech document is depressing. It mentions bugs I haven't seen yet.

I ended up using a Lee's plastic powder measure dipper for reloading. 3.4cc's per 5 gal. of water does the trick. Could also use a syringe graduated in cc's.
The main advantage to using Admire in your transplant water, rather than as a foliar, is that stuff is deadly to honey bees and other beneficial insects. As a systemic it only kills what munches on the plant.
