Neem and other insecticides

[Bona Fortuna]

Hello icmag!

Just wondering if a plant can systemically process neem and other insecticides. Meaning, can a plants roots take up these chems, organic or not, to use for protection? Is foliar the only way to protect your plants?

Just an idea bOuncing around in my noggin...thank yall

with neem it can be taken up through the roots and end up having a systemic effect. many growers add it to the soil as a preventative.

If your growing indoors and have pests problems and/or pm, most likely it's the environmental conditions. Neem, h202, tobacco, chili spray, rosemary... I tried it all with minimal success. Then, I circulated the air better, watched the temps and humidity and all those pest and pm literally vanished.

Now I spray compost tea once per week and occasionally something like Mighty Wash but that's it...

Check your climate first...

Gaiusmarius, thank you!

Hle144, that's reasonable. I'm thinking more or less for outdoors though. I feel like outdoors and neem fed roots would seriously help guerrilla plots.

I stop the neem about 2 weeks before harvest and certainly none after flush

Systemically, or foliar?

I wonder if systemic would influence taste at all, if you were to root feed till harvest. Any input icmag?

I just posted a thread on this the other day and got a ton of opinions on the different forms of neem. I wanted to use neem seed meal in the soil and was concerned about taste. everyone agreed that the meal did not effect taste while there was varying opinions on foliar opplications. what I learned from looking up some of the opinions was this: 70% neem has the active ingredient removed because when oil and azadiractin are mixed it becomes unstable. 100% neem has azadiractin in it. both will work to repel pests while imo the 100% would be more effective if you actually had a pest incidence. now, azadiractin can be bought with no neem called Azamax. on the product label it states that it is systemic but only for a week and a half to two weeks so reapplication is needed. Neem photodegrades from the plant so it lasts anywhere from 48hrs-week depending on who you ask. the oils from neem also clog the stomata inhibiting transpiration. systemic effects will only kill bugs that are biting so it won't repel so if you're guerilla growing outdoors, I would suspect you would want something that would repel and kill which would be the 100% neem. that needs to be used with a wettening agent or dish soap. some people like to blend it in a blender and then shake as they're applying.

I have heard really good things about Sea Shield so after looking into neem and some other stuff, that is what I'm going to use. I'm only mentioning this because I haven't seen it posted too much unless you're following certain people. http://www.growbetterfood.com/products/seashield/

Amazing! All the info I needed!!!

I like Azasol, being water soluble. No oil. As a result, more systemic. I don't know how long it lasts. No oil mess. No clogged stomata. No phytoxicity. Long shelf life. Good luck. -granger

If I were to mix azasol with an organic tea, would that cause any bad reations? Or would it be smarter just to make a seperate tea and azasol feeding regiments?

Check the label or their website. I don't think it's a problem, but I would not brew the Azasol. I'd add it to the tea just before feeding. Good luck. -granger
