Recovery of Plants from Root Aphids

[gloryoskie]

Like the title says, have had several mums
suffer the indignity of infestation. After root
drench of Spectracide am attempting a come
back.

Leaves are showing acute mag def, close to
losing some key genetics, maddening.

Have transplanted to sterilized charged coco.

Reduced lighting.

Reduced nute feeds.

The plants lost much root mass, but new
growth is promising.

Adding kelp to the feed as well as 1/4tsp per gallon of Epsom.

Any help would be awesome, have read many threads
on the subject, just hoping for some new insights.

If all is lost I can recover most from seeds I have,
but would like to save as much of what I have now.

Pics upon request.

adding seaweed is excellent...

when you say replanted did you actually wash off the roots?

i went through bad times with RA but was generally able to rescue most of the affected plants once i had dealt with the RA...

btw i find adding neem cake as a top dressing (about 2 cm deep) has worked very well at keeping RA and FG from out of my grow rooms..

good luck

Use a good root stim repeatedly in addition to what you're doing. When you start feeding, go with a transition feed. Neem cake is good. Get good runoff each time. Inoculate with Great White or similar, or better, with an EWC ACT. Good luck. -granger

Thanks fellas.

Every plant's root ball was cleaned of the old coco.
Rinsed/jiggled in a bigger pot of ph'd water until just the
roots were there, like really big clones.

The roots were badly pitted and off color. barely
any fine hair.

Grow box was completely stripped and sanitized. Filters
replaced, the room where the grow box is kept has also
been sanitized, like a hospital.

The plants will get another soak of Spectracide today.
More aphids found on two smaller plant's root ball.
No flyers found, just rooters.

Larger plants showing promising signs of recovery,
good root growth and greening up.

Fucking looks like a yummybud grow, lanky plants
with sparse growth, lots of stem. sigh.

Tossed all the new cuttings and newly rooted cuts yesterday.
What a nasty lesson to learn.

The grow will rebound, count on it.

I can always pop some seeds, lol!

sounds like your plants are bouncing back but it might be an idea to start new mums...

may have been a waste to toss the cuttings though, a quick treatment or planting with neem cake should have seen them bug free...

good luck.

Yeah, the rooted cuttings were goners, stalled and leaves
falling off, roots were pitted and brown,showing no promise.

The new, un-rooted cuttings were browning, edges
curling and droopy. Probably a result from the
health issues with the mums when cut.

I've taken cuttings from the rebound mums,
they remain green and spry, a few days now.

Should root later next week and I'll be back
on track.

I grow micro, so no one but me is suffering
from the delay the problem caused.

Thanks for the support!

The veg box plants are out of danger, amazingly
no plants were lost. Cuttings are showing root nubs,
leaves and stems healthy.

The addition of kelp to the feed has proven to be
the turning point, as well as not pinching damaged
leaves.

The flower box plants are showing signs, so will
do a dunk on them also. Interestingly, the leaves
show a nitrogen def, not mag. Its the bugs. Maybe
10 flyers a few weeks ago, translated to hundreds
of rooters, all the flowering plants are infected.

Temps in the upper sixties, humidity around 55%+/-

I pulled a plant tonight and set the cut root ball in a
bowl of water. Lots of aphids swimming and generally
having fun. Not for long.

I will treat all but the one plant that is ready to chop this week.
Yield on the cut plant was low as expected, flowered in a 6 oz cup.

The larger plant will yield nicely, the infection late in flower
seems not to have done much harm to her.

The other plants have at least 6 weeks to go, no worries.
