The one with 75 on it. 75% imid. Package looks similar too what I got. Basically knockoff Merit 75.View attachment 4386559

I placed my order now I just need to survive 10 days for the stuff to come in. Im still going to do a hydrogen peroxide watering to hopefully slow down aphid production. Also I asked for help on instagram and someone suggested this to me for flowering plants. I might try one of these methods while I wait for package.


“Wash plant, then use 1 of these methods.

2 cups water two cups chopped tomato leaves strain, then add 2 more cups water. Spray bottom of leaves.

Or

Chop an onion, a garlic clove, blend in 2 cups water strain and spray under leaves.


Buy lady bugs they thrive on aphids”

Ladybugs or green lacewing larvae will help control the aphids above the soil line but won't do much in the way of getting rid of the ones feeding on the roots. As for the other organic methods, I do not know.

Use chemicals if you must but aphids aren't such a big deal. Go around and rub each leaf, defoliate and then blast with the hose and you'll knock them back without any toxins. Or, water and dish soap to kill them then rinse with hose to remove residual soap.

I will be trying one natural method like this regardless because waiting 10 days without doing anything will be to much harm. Will dish soap be okay for attempting to kill the ones in the roots too?

What did you buy? Pretty sure at this point you have to go botanigaurd.

I can get that in Canada but from reading it isnt that a foliar spray? I bought Imidacloprid, you dont think that will be enough like the others said?

This might be your downfall mate, root aphids are harder to control... If it was me I'd attempt to drown them by dropping the pot into a bucket of water for half an hour or so... Your plant won't die but they might... I've never had the root aphids, only leaf ones...

Forget that... Google says they don't drown ... Bummer

I used it as a soil drench and it works for sure and organic. I don't think you are aloud to use a systemic chemical with flowers on your plants.

Damn okay, I didnt know that. Ill research a little more and see if the stuff i ordered is harmful during flower. I will try extremely heavy insecticidal soap until then. I’ll probably order that botanigard still too.

myke said:

Ive had them before,safers soap is ok to use.soak a towel rub them off so you dont get any on buds.Then spray with water a day later.Repeat every 3 days,but it maybe a lost battle as there everywhere this time of year.

damn didnt realize aphids are that much of a problem

just 1ib of botanigard, how far will that go with a drench? Also will synthetic fertilizers make kill the stuff in the botanigard?

Also on the website it said its for fruits and veggies so im assuming its good to use during flowering for cannabis right? I bought botanigard 22wp

also got myself some Nematodes
https://www.amazon.ca/gp/aw/d/B07L56BWXK/ref=ox_sc_act_image_1?smid=A1FF5RQDLELKAF&psc=1

never mind apparently they arent good for cannabis

i take that back there is such things as benefical nematodes which attack larva and aphids then other nematodes that attack the roots like aphids.

If you use botanigard or nematodes dont use chemical fertilizer or pesticide. It's like pissing your money away. I used nematodes but they were too slow acting, so I used the imidacloprid. Im still in veg though. I wouldn't use it past week 2 in flower. Maybe something containing gamma-cyhalothrin.

I believe the Nematodes are okay to use with fertilizer but ill double check. I also will have the chance to buy these https://www.koppert.ca/content/Canada/Product_Sheets/Aphid_Control_-_Product_Sheet.pdf but im not sure how useful these bugs would be outside.
I also thought the botanigard could be used with synthetic fertilizer but i guess if its biological it makes sense the synthetic stuff kills it. Any suggestions for a simple organic fertilizer I can switch too?

Im thinking the way im going to approach this situation is to heavily spray with insecticidal soap daily and dehydrate my plants as aphids cant breed well in dry environments. Once dried I an going to run a hydrogen peroxide solution through the plants in attempt to kill the ones livings below (still spray with insecticidal soap too) After this I will let my plants dried out again and ill put my nematodes in. Once the botanigard arrives I will start using that (im assuming this kills nematodes as well?)

No. The botanigard should be compatible with nematodes. I dried out my pots but the root aphids were still breeding. They really messed up my biggest 4.

“It contains 20% of potassium salts of fatty acids and 0.2% of pyrethrins.”

yeah the growth of my favourite plant is extremely slow. Just for shits since im going to lose the plant i may try a insecticidal soap drenching and see how that goes.... I might let it sit in the roots for 10 mins then flush it out.

Hold the plant up in the air so you can drench every sq mm.I spray every 3 days with safers soap,doesn't seem to bother the plant.

Oh man there is some bad advice here....

This to me looks like the green peach aphid, check it out here. http://ipm.ucanr.edu/PMG/r604300111.html

Root aphids generally do not feed on the foliage unless the infestation is really bad, and you would be seeing all kinds of issues that typically mimic nutrient deficiencies as the root system is damaged. For example rice root aphid will mimic magnesium deficiencies in high enough populations. So unless I am severely mistaken, these are garden variety aphids and are not that big of a deal. A heavy spray of insecticidal oils will deal with this issue. Botanigard will also work but, just like the insecticidal oils you must ensure good coverage of all foliage and stems and it will take about a week for the fungus to kill the insect and its eggs. A few treatments of botanigard a few days apart and this issue will be dealt with.

For the love of god don't use systemic insecticides on bud that you intend to smoke... holy fuck that is just really dumb advice. Imidacloprid is a neonicotinoid, which is generally harmless to mammals as far as I know, but ive never smoked it so I really cant tell you what putting fire to that chemical will do to you or anyone you sell that bud too. Jesus Christ. There should be a filter on this site where you upload a pic of your applicators licence before you tell someone to use an EPA restricted use chemical....

I know of no nematode species that are on the market that will parasitize aphids. Fungus gnat larvae and thrip pupa sure, but not aphids. I wouldn't waste your time or money on that avenue. They can be tank mixed with salt based fertilizers, but require moisture to live, so the idea that you will dry out your soil to the extreme to combat the aphids will just kill those nematodes you apply.

Just... just go get a insecticidal oil and spray early in the morning before the sun is full strength to avoid leaf burn and you should be all set. If you feel as though you must spray potentially harmful chemicals, or if you intend to spray in the future at all, why not go get you applicators licence and learn about the potential dangers of using these chemicals and how to best make use of them in a safe manor.

I will give you a much better answer shortly as I am at work. How about the 20% of potassium salts of fatty acids and 0.2% of pyrethrins. I was reading up on this and if i use this as the root treatment i should be fine as it I wont get it in the buds. Im buying botanigard 22WP. I will give you a better answer shortly my apologize. Thanks for the help though!
