Can a systemic fungicide be applied to the rootzone?

[bench warmer]

I'm wondering if it's possible to water a diluted mix of a systemic fungicide into a plants rootzone.

I know Eagle 20 is meant to be sprayed on leaves/stems but I'm wondering if it can effectively be applied to the substrate.

Does anyone here have experience doing this?

Peace.

same question. I am looking at either Serenade or Bonide Copper.

My problem is leaf septoria (orange spotty fungus on leaves that causes early defoliation and is very contagious between plants).

Serenade foliar spraying has worked well to *halt* any further spotting on the leaves, but not to prevent it, as this fungus is systemic.

I tried an H202 flush, no noticeable results (1.5ml/G 35% food grade). Serenade and Bonide Copper/Sulfur - great for temporary control. NEED ERADICATION.

Being in indoor grower this is an especially rare fungus to get, or so I gather, and it seems to be even harder to get rid of. At this point, every single plant in my 3 grow areas has leaf septoria, from the leaves touching eachother or because they were cloned from eachother. I need to systemically treat the soil and the roots to eradicate this shit. (If you're curious, I got this from having ridiculously high RH at night in my grow area when I was running a humidifier to try and knock out these bright yellow Vapor Pressure Deficit stripes on the leaves - like 90%RH at night in the grow room - fungus heaven). Turns out VPD doesn't defoliate and kill your plants, funguses do!!!! Lesson learned, dehumidifier re-employed, i'll live with low humidity and some yellow racing stripes.

Does anybody have any experience applying fungicides like Serenade or Copper to the soil / roots?

I know Neem Oil can be applied as a systemic, or so I've heard, and it has fungicidal properties (but i don't know if it kills septoria), how about those who have used Neem products systemically, did you find the fungus stopped appearing?

Any experience / advice would be most welcome.

thanks

See the real deal here is most gardeners treat a fungicide as just that ...a mold or bug killer, but your question does very much depend on what chemicals you are playing with .....very much.
Neem Oil has recently been proven to be systemic as in the plants drink it up ...from the root zone, applying 1 tsp...to a gallon, will give great results, but I urge caution as often it will kill benefical bacteria too, ...good luck

Sure you can. But it will kill a lot of the bennies in your soil.

i had this fkn fungas last year and it ravaged a few my plants. i seen this year a couple had it in early veg i hit them with eagle 20 and now they are healthy as can be. check this link for a systemic fungicide that i havent bought or used but i have been thinking about getting it for next year just in case. its a systemic copper fungicide. the only thing that worried me though was bc its only for ornamentals and trees,so i contacted this company and they said this "Phyton 35 is our formulation which can be used on food crops" which i have been trying to find info on. they also said it will kill botrytis blight

thanks for the responses all.

I always repopulate the bennies with Great White etc any time i do something to kill them (like h2O2 flush) so that's not an issue really, looks like I'll be trying a Neem Oil soil treatment and looking into this systemic copper one that was posted above. thx yall

thanks for putting a name to my mystery prob.
someone told me I had a fungal thing and recommended actinovate.
i used it as a root drench and sure enuff it worked.
you can also take cuts from the infected plant and soak the cuts in actinovate for a few days.
my prob is it hit the only mother i had of my leia og.
thank you for actinovate!

this is what my leaves ended up looking like

Ridomil is a root drench fungicide that is absorbed to work systematic. People have been using it to fight fusarium. Didn't work for me.

Seems that the feds banned some copper based fungicides that people had been depending on, so there's a search for alternatives. I think Actinovate is bacteria based and can be used as a foliar as well as a root drench. Rootshield has Trichoderma fungi which prey upon other fungi, hopefully the ones you want rid of. It is a root drench, but not systematic.

did ur leaves look like that after u used actinovate? i have actinovate that im gonna be using as part of my IPM program from week 5-8 on 10 week strains. leaf septoria is a bitch! last year it wiped out my holy grail kush. it fked it up so bad i didnt even pull it. i just left it there to die bc it had zero grams of smokeable bud on it. i have found that DNA strains just dont make the grade when it comes to guerilla growing! i have been thinking about buying their silver bubble since its mold resistant but the thing is mold isnt the only issue anymore we gotta worry about shit like leaf septoria and a bunch of other shit when out in the bush growing.

Hey CR i been interested in rootshield but i was wondering how does a drench help control a folair disease?

i did the actinovate on all but 1 plant that was outdoors.
the ones treated are rebounding,
still a few yellowed leaves but actinovate did the trick it seams
I took healthiest cuts from the best plants and let em sit in water treated with act. for a few days and will use these next round.

btw the 1 that wasn't treated fried-n-died.

Always like seeing testimonials on Actinovate. My experience with it is good. I've only used it during bloom as a preventive. Three apps from week 3 to about 2 weeks before harvest. Or 4 for longer season strains. Never had PM, and only twice on a total of 3 buds, 5 year period, have I had Botritus. On two strains, which I don't grow anymore for that reason. With my environment at very close to optimal, maybe I could get by without it, but I'm not going to risk it.

If I were to have a problem jump up, I'd do a soil drench and a foliar. I'm lucky to have not seen Leaf Septoria so far. Good luck. -granger

I don't think a drench of Rootshield would do anything for foliar problems. As it's name indicates, it is for root-zone issues.

i didn't know so many others were already on the act. bandwagon.
so i take it it id safe to use in bloom then.
Q on your app's during bloom
was it sprayed on? and how much per gal?

 

[Hammerhead]

If anyone else is using Phyton 35(food crop safe) its (10-20 oz per 100g)3-6 mils per gallon for Mint leaves. For Parsley its(20-40 oz per 100g) 6-12 mils per gallon. I'm not sure what is closer to cannabis so I'm using the lower dosages. Tomatoes are also 20-40 oz per 100g.

 

[Loc Dog]

If anyone runs across this post, eagle 20 - myclobutanil is safe for produce but turns to hydrogen cyanide when burned and is banned for cannabis.

Would love to know if anyone has found a recent product that works for pythium, fusarium, and botrytis.

WARNING...not all 'food safe' items are smokable. How much copper fume does one want to inhale?

Not only that, but 'food safe' stuff isn't always 'edible'. Some cleaners are deemed 'food safe', meaning that they can be used in the kitchens and deli's without poisoning people. But really not meant to be eaten.
