That artical says leaves residue on leafs not in them ?
Joe, could you elaborate on this? 
Microscopic world is beyond my poor knowledgeā¦

I would think the amount of spinosad in buds should be minimal with a soil drench. Itās not the same level that would be on sprayed buds. Plus that level should decrease as time goes on. I wasnāt excited to soil drench my 6 year old no-till soil with spinosad when I got thrips. But Iām pretty much over it. It really cant last that long in soil since bacteria break it down, as does time, light, and water. Iām sure thereās no trace after a bit.
Iām sure itās not great to smoke it but there really canāt be that much. And Iāve smoked way worse stuff. Ever smoke Mexican schwag? That shit has been sprayed with all kinds of shit and lots of times has traces of mold. Plus just breathing the air is unhealthy sometimes. I do try to make smoking as safe as possible but Iām not too worried about a little spinosad being absorbed through plant roots since Iāll rarely ever use it. Iāve only had to use it one time so far. But I get it if people donāt want to use it. Itās just too easy.

So if soil drench all of plant absorbs it
If I take a cut 3 weeks later from growth that was not there at time of soil drench
Will that still contain spinosad ?
And later if I take a cut of the new clone , will it still be there

Basically translaminar canāt transfer the substance as far as systemic. Like if you spray a leaf it will stay in the leaf but be able to move within that one leaf. Where systemic can spread the substance farther, say from the roots up through the plant and into leaves and buds.

@George is thinking and now so am I
When his plants fade at finish
And plant absorbs nutes from leaves , will spinosad travel to buds with the nutes ? From leafs previously sprayed earlier in grow
Or as plants use up nutes from lower leafs during flower etc if they were previously sprayed

Thanks, Joe says itās systemic, letās wait for him or we will have too many questions without answers ā¦

Yes, if you spray leaves they will absorb it and then spread a portion of it to other areas since itās somewhat systemic. But the majority will be where it was sprayed.

In the field, spinosad activity is characterized by cessation of feeding and paralysis of exposed insects within minutes. However, these insects may remain on the plant for up to two days. For this reason, growers and scouts should wait a minimum of two to three days to evaluate control.
Foliar applications of spinosad are not highly systemic in plants although some translaminar movement in leaf tissue has been demonstrated. The addition of a penetrating surfactant increases translaminar movement and activity on pests that mine leaves (Larson, 1997). No phytotoxicity has been demonstrated with this product.

Referenced study in the above:
Though, the half-life of spinosad exposed to environmental factors is ~2-16 days. Half-life being half of the product decomposed into something else. When not exposed to sunlight, the half-life can be very long ~30-259 days.
Reference:
Here is a study regarding spinosad on tobacco. I have not read this as of yet but may be pertinent.

Heh heh I was having breakfast. Yah itās like PadawanWarrior says. Once you spray the spinosad on the plant, it enters the tissues where it touches. Thatās called translaminar. Systemic is when it enters the plant, and the plant transports it to all the tissues.

So better not to soil drench and when folier no wetting agent
Is there a difference in led v hps in degration time ie no uv with led

I would summon johnny with more experience using spinosad than I. He says never to use it, because months later your product will be rejected by lab testing as contaminated. Unfortunatelyā¦ I wonāt summon him because, ugh, heās at the hospital high off his ass on morphine. Iām sure everyone knows the story.

Iām on a roll : )
Shootin the breeze
So say I use a folier product like canna cure , then next day spray with spinosad
Then a week later blast with uv
Sending good vibes to Johnny : )

Iām sure there are no traces of it in my pots anymore. Soil microbes take care of it quick. Half-life of 9-17 days. Well maybe a trace. But itās probably so low itās undetectable.
Spinosad also sticks to soil and has a very low potential to move through soil towards ground water. In field studies, no break down products of spinosad were found below a soil depth of two feet. In the top layers of soil, spinosad is rapidly broken down by microbes. Soil half-lives of 9 to 17 days have been reported. After it is applied, spinosad is not likely to become airborne.

Why not cut a piece of cardboard
Cut a radius line out so you can slide over top of pot makin cardboard bigger than pot so it doesnāt touch soil , and pre spray that top and bottom instead of the soil ?

I think I know what youāre thinking. You mean if you block off the soil completely the thrips wonāt be able to complete their lifecycle and die off. As long as it was completely blocked that should work even without the spinosad since they need the soil or coco for the pupa stage.

Iām sure they would still travel to soil somehow , but if cardboard was pre sprayed , then itās a done deal

Oh man, I wish that lifecycle applied to all thrips. Would make killing them so much easier, since I donāt use soil, or any medium for growing. Uuuuuunfortunatelyā¦ some of the little fuckers complete their lifecycle right on the leaf.
