Root Aphids! Careful w clones...

[sarah louise]

A systemic pesticide applied to the leaves will slowly, but eventually, get rid of root aphids... good for bonsai Junipers but not really a usable solution for cannabis. Have to agree with Johnthemick, if clones came in with root aphids, they'd go straight in the bin.

The quickest way to check for root aphids is slip off the pot. Root aphids will leave a whitish fuzz that looks like beneficial fungi (mycorrhizal). The difference is that mycorrhizal fungi don't move and aphids do.

If you regularly need to buy in clones I think it would pay to have a small quarantine area, where new material can be pretreated before entering your garden space proper.

I think a beginner is best suited to start from seed rather than clone!! It may take a little longer and be a bit harder to obtain (unless you want tga/subcool LOL), but it'll pay off in the long run!

hmm...this is a new one. i laugh at people who say they know all there is to know about mj cultivation. in my 30 years of studies and at least once a year i learn something new.

meded so you can mededicate to mededitate

Well, I think the problem is that they come in as eggs... eggs in soil are going to be damn near impossible to find. You won't notice any symptoms from them at all typically until about day 25 of flower! So, it's not as easy as checking/quarantining your clones.

In the future I'll dunk all foliage and roots in a neem solution (possibly a pyrethrum solution first after testing). The root dunk is just as important as the foliage dunk. Then I would inoculate the soil with predatory nematodes after a week or two and the neem/pyrethrum has been rinsed out.

From my understanding these things don't tend to cause as many problems during veg because the roots will grow back as quickly as the bugs can eat them. However, in flowering the roots won't grow back at the same rate (if at all), so the aphids become a HUGE problem ultimately killing your plant if unchecked.

finally figured out i had these little fuckers. going to hit them with azamax and then imidacloprid.

kept chasing a nutrient deficiency. glad i finally figured it out.

We use nematodes, they will eat eggs but once you have an infestation I'm not sure how effective they will be. They do completely eliminate fungus gnats though, but not if you miss a pot!

Root Aphids are not native to CO so you won't track them in from outside, vectors of contamination are usually potting soil, although I know some guys that just got them in their hydro system, new hydroton is the only way we think they got in...

nasty little buggers. Got em for the first time this past fall.

[puntacometa]

Every single clone vendor thats come through our door has had either powdery mildew, root aphids, spider mites or all three..

No fungus gnats yet?

No fungus gnats yet?

yeah right, something is missing in that list. although not an untruth in some cases.

I've been chasing what looks like N and P def. Mainly P.... figured I'd look..... after 20min of pouring over my root ball with the microsope I found nothing. :wtf: I'm hoping that's a good thing.

I haven't seen any wingged thinggs in my room in several months (believe they were fungus gnats from the new bag of soil at the time) My problem started about a month ago, and is only effecting vege, my bonsai moms to be exact. Flowering has been un effected.

On the plus side I hit my affected girls with a heavy P fert last week and things seem to be improving. So I've got my fingers crossed it was just a deficiency because those little bastards sound like bad f'n news!!!!
