Dyna-Gro Pure Neem Oil?

[whereisbrianV.]

Dyna-Gro neem oil has NEVER failed to rid all of my pest within two spray downs. The shit stinks to hell and will render a spray bottle useless, but for no bugs I will deal with it.

"products containing extracts of neem oil are registered pesticides, tested and approved by the EPA for use as a pesticide. Remember, extracts of of neem have had the ACTIVE COMPOUNDS FOUND IN NEEM OIL REMOVED during the refining process, and these products usually cotain alcohol or phenol used i the extraction process. Theses extracts of neem have an emulsifier added to help it mix readily with water. Pure or "crude" neem seed oil must be mixed with an emulsifying agent to accomplish this. Pure castille soap can be used as an emulsifier when using pure neem seed oil. warm water should be used when using crude neem oil since it becomes soild at room temeratures."

also taken from IPM of Alaska

Thats why I was suggesting sticking with pure neem oil or cold pressed neem oil. You don't want the chemically treated stuff, cause they have rendered out most of the active compounds.

Cold pressed neems like dyna grow and einstein oils have not gone through the chemical extraction process and still has all of the goodies still intact.

This is the same type of thing that happens to seaweed when it is processed. There are two ways to process seaweed for fertilizer, crude chemical extraction and cold pressing. The chemicaly extracted seaweeds are your maxicrops and nitrozymes and the cold pressed are like bio bizz's alg-a-mic. These two processes render quite different results. The chemical extraction ruins nearly all of the micronutrients that were available and renders them useless, but it enhances the hormonal properties of the seaweed, making the concentrations of hormones rise. The cold pressing techniques does nothing for concentratin the hormones, but keeps the essential micronutrients intact and ready to be used by your plants.

So...seaweed is not seaweed is not seaweed. There are differences from brand to brand. Same goes for neem oils...not all are created equally. Go for the cold pressed neems, they contain the compounds needed to do the job right


Do you want something that emulsifies easily? Or do you want something that works? Personally I don't want something that has been chemically altered and then has addatives(emulsifiers) added to make the product appear to work better. Just my opinion...

most cold pressed neems are not labelled as pesticides...most are labeled as a leaf wash or leaf polish.

Clarified Hydrophobic Extract of Neem Oil is the chemically processed neem and is labeled as an insecticide...yet contains very little to no active ingredients.

Cold pressed Neem is labeled as a leaf polish and contains the goods.

Leave it to the gov't to only allow the chemically processed products be labelled as insecticides...the natural unaltered goods can only be labeled as polishes and washes... thats the world we live in...

I use dish soap along with my neem as well. When I don't have hydro neem, I use garden safe neem oil. I also mix my own pepper sprays for use in flowering. Its vodka, habaneros, mint, and a touch of water in a blender. I let the mix sit for a week or so.When I spray it, I add a tsp or 2 of peroxide to the mix. Now you can use neem through veg and flower and hit the plants with the pepper spray to finish out.
The bugs hate it and it prevents mold and fungus as well.

Azadirachtin, a tetranortriterpenoid compound, closely mimics the hormone Edison, which is necessary for reproduction in insects. When present, it takes the place of the real hormone and thus disrupts not only the feeding process, but the metamorphic transition as well, disrupting molting. It interferes with the formation of chitin (insect "skin") and stops pupation in larvae, thus short-circuiting the insect life cycle. It also inhibits flight ability, helping stop insect spread geographically

Tests have shown that azadirachtin is effective in some cases at concentrations as low as 1 ppm, but some producers use alcohol in the extraction of neem oil from plant parts which causes the azadirachtin to be removed from the oil. Some products touting neem oil as an ingredient actually have no measurable amounts of azadiractin. I use what is referred to either as cold pressed or virgin neem oil. You may also occasionally find it referred to as "raw" neem or "crude" neem oil...

...The application of neem derivatives does not provide this immediate gratification. There is virtually no knockdown (instant death) factor associated with its use. Insects ingesting or contacting neem usually take about 3 - 14 days to die. Its greatest benefit; however, is in preventing the occurrence of future generations. It is also interesting to note that in studies it was found that when doses were given, purposefully insufficient to cause death or complete disruption of the metamorphic cycle, up to 30 surviving generations showed virtually no resistance/ immunity to normal lethal doses, so it appears that insects build no ‘resistance’ to azadiractin.

Anybody need anymore info? DJ.. where you at?

 

[DJ_highst_]

I am right here, thanks for chiming in here with that info, I still havent read over it all. I am starting to understand that more of the confussion is based on what they can put on labels and what they print on them doesnt always give the proper representation of what they are and what they can do. Fuck the EPA. Let me soak all this in and see if I can get a grasp on what the hell is going on.

I was thinking of going out and buying every kind of Neem Oil, Concentrate, Bio neem, Clarified Hydrophobic Extract of Neem Oil, etc and doing some head to head comparisons to see whats the best way to go.

cold pressed neem oil has Azadirachtin after all. Check out this site with alot of organic and biological products

Got an anti mite foliar spray of Dyna-Gro 100% Neem Oil - mixed it with AN Wet Betty "Organic" & a dash of Chi..

Powerful Peppery smell - Seems leaf Chompers would hate it..

 

[steve green]

could i add an organic muskie mix in + neem oil as a foiler spray during veg to feed more N and keep bugs away?(organic grow)

Also when spraying with neem ..how much does everyone spray? do u soak the whole plant including stems and under leaves? Is there prefered times to spray?

im using neem oil for the first time ,so this thread is already helping me.
thnks everyone

Coat the mofos, Steve!
Best application times are right before or right after lights on or off.
The reason for this is that any foliar spray has the potential to mess your leaves around under light and/or heat. Best to do it early so that it dries quickly or late so that it dries with the lights off. Also, the bugs are slower right before the lights come on and they slow down after the lights go off, making your application more successful.
As for mixed pesticide and nutrient sprays, all the literature says to avoid it unless you personally have success with it. Only way to know is to try I say, just go extra light on the nutrient.
With any spray you want to cover the whole surface of the plant and i like to drench the top layer of medium for good measure.
Good luck, little buddy!

 

[steve green]

thnx humble, im gonna keep soakin em i quess..it does seam to be working. im gonna be misting them from now on when i turn the lights off..just to give them a lil break/. yea now im even more thinking of NOT mixing the two ..maybe just do seprate applications.
thnx for the quick reply

I love neem oil. I use it every 3-5 days. No bugs or fungus. Neem is great...

 

[wreckMEplease]

I've been using Einstein oil on my last 2 grows. When i started my first grow i had a few gnats flying around but since then i haven't seen a single bug in my room. I havent tried any other Neem oils but the EI is a great product.

Very good info on the Neem here. I began using cold pressed on my outdoor plants this year and they look MUCH healthier.

One tip I didn't see mentioned was to mix not only with soap, but also with warm water (not too hot!). This really helps mix the oil and makes application with your trigger sprayer much easier.

The safer soap I used last season really had no effect I could see . . . now I understand why (no azadiractin)

 

[1tytersx]

i personally never had any success with neem oil. i tried couple different brands and they never really worked, even spraying every other day for a week. they would always come back. hidhut sells floramite in small containers and floramite kick ass. after 1 spray i was miteless. floramite ftw

 

[humble1]

neem is definitely for the tree-hugging set. floramite works, but so does Roundup, kin?
lucky 7 has a point about the warm water, but don't take it over 70 degrees fahrenheit or you're prematurely burning off some of your azadirachtin (which has a low activation point). also, follow the directions on the bottle as per your soap or wetting agent.
When i was rocking dyna-gro neem i used 1 tsp a gallon as an emulsifier. Now with the einstein oil i only need to use a few drops. Either one works, but I think the einstein oil has a longer shelf life.

 

[steve green]

does anyone know if too much neem is dangerous? what i mean is from daily applications(foilar) of the same amount...not alot a once.
sorry to be confusing. Can u spray daily/?

this thread is super helpful for anyone like me who knows nothing about neem oil.
Thnx everyone
this communty is awesome!

 

[kokua]

if over applied and left on the leaf oil will clog the stomata on the leaf. Stomata are small pores on the leaves that allow gases and water pass to and from the plant. We need these open...

No one wants clogged pores...

The best way I've found is to spray the entire plant (every leaf) as thoroughly as possible. Let the oil hang out for a few days, then follow up with a spray to wash off the residual oil. I usually mix in a little seaweed in with my wash spray for good measure. Apply the oil 1x per week for up to 4 weeks to break the egg laying cycle of whatever pest you are attempting to erradicate.

So...if you spray with the oil 1x per week you have to wash off with the plain water (or seaweed water) at least 1x per week as well. I usually treat, then wait 3 days to wash off. Then I treat again 3 or 4 days later, competing the weekly cycle.

 

[steve green]

thnks for the tips kokua ,i kinda know about the plants stomata ,and how it could close with temp over 80+. and how important it is to foilar feed when its open. i will take your advice kokua..and do like a mist with water after i use neem. However i think im gonna mist them more then 1time a week with a light neem mix,but i will deffinetly also mist with water to remove extra oils like a day or 2 after. i really didnt think it was necessary to rinse the oil off with water,,thnx.
ohh and thnx Clowntown for starting this thread your the man
