'Practice tet' follow up.
L to Rt..
#1 crown is done top half at least ..DOA. Sm shoot coming from very bottom of crown/top. Now discarded. This plant never wanted to 'go'.
#3 is a fan from each side.. sliced and separated (now 2), the crown not brown/showing rot.
#2 I chose to take the active growth off the crown.. the inner material showing normal color.. no rot/brown.
#4 far rt has nice center growth.. nothing to any sides.
2nd pic.. 2,3 &4.
All of the original formation leaves from each plant are more rigid than the norm. #4 likely the most.
Note #1 unit of 2 .. one I pried off to allow it to continue sending it's own root system. It's mate on the other side sliced down thru the crown.. lots of stored calories under it.
#2 crown removed save the area the growth is originating from. Nice internal color as it should be per sliced area.
#4 far Rt.. last crown treated showing most promise. Looks to be extended meristem growth. I believe this plant rec'd the weakest solution.. failure to shake the container.. least drop size applied. NOTES...NOTES... grrrr. From memory.. not good.
Again this tet experiment for learning.. all of the piece were different sdlg's headed for composting. Stuck them in the ground.. why not.. if they grow out might be things of interest.
Slid the Stella into the ground also.. several show promise. Time'll tell.. that mostly is the conversion game.
My 'solution' strength is 20-25%.. surflan into water. The chem agent is 40.4% Oryzalin.. online mixes are all over the place.. and then some. Comedy.. one goes to apparent exacting lengths to make the "stock" mix and then goes bananas tossing together the actual mix for application.
One finds surflan mix rates from 1:100, 1:200, and the extreme from a guy.. DL one no less.. using ~1:140,000. How to mix that last rate....
From memory (look out) that's 10uM.
Gimme an eye dropper... calibrate those drops to a unit ANYONE can relate to.. mix away. Q becomes what ratio............20-25% apparently is not the death knell. Yet the ability of each cultivar to handle the junk will vary. So.... how far to scale it back.
EDIT/FORGOT to ad my guestimate ratio. Not set in stone--- considering 1:200-250 range. I do actually have a scale to weigh the surflan... won't bother.
NOTE: had to edit plant sequence numbers.. error original.. all L to Rt.
YET more edits...notes for myself.
--I read DMSO very hard on plant material.
--One source states surflan contains ingredients active as solvents. I find no reference to that..
same guy w the sloppy "stock" solution to application useage.
Surflan label:
-oryzalin: 3,5-dinitro-N4N4-dipropylsulfanilamide ...... 40.4%
Inert Ingredients ........................................................... 59.6%
Total ................................................................................ 100.0%
Tank mix--Surflan A.S. Alone
Make sure spray tank is clean and use only clean water. Fill
spray tank 1/2 to 3/4 full. Start agitation and add the required
amount of Surflan A.S. Continue agitation and finish filling the
spray tank. Maintain continuous agitation until application is
completed.
WHICH... IMO makes a 'stock solution' nonsense. This orange chem doesn't stay mixed... clinges to container inside surfaces.. try to wash it out.. takes some effort. Shake it very well..
the mixed solution prepared.. and apply... before it settles out.
The 'Stella' 20-25% solution had a small dose of acetone.. the chem mirror image of DSMO save one de-tale. Acetone has a carbon atom whereas the DMSO has a sulfur atom at that location: they do the same oxidizing routine. Surflan is noted as being highly soluble in acetone... while I assume DMSO can/does make surflan more soluble, I find no reference to it specifically.
De-tales. Gets a mite deep I suspect to get a conversion rate worth it. A challenge.. something to learned. I doubt colchicine is the conversion agent used by the few proficient at it.
Vastlan herbicide is triclopyr choline.. essentially the same effect as oryzalin on plants. Weeds noted to build resistance to it. To be investigated... even less harsh on meristems??
??'s
--my tet experients used plants at or headed to the compost pile.. those meristems looked cream white. Essentially I think that's same appearance of Stella's cut after clump separation: seems wrong. Tets I waited mostly to note meristem starting to green.. then treated. Seems like (beware.. from memory) the 1 0f 4 tets whereas the crown died and pushed a fan bottom side did not green/wasn't given adequate time (?).
?? inground treatments. Carving the challenge.. have ideas.
?? Kinetin arrived today.. how much to use?
