Met52 for Root Aphid control
- Thread starter Thread starter inreplyavalon
- Start date Start date
I have heard of folks using it with wool but i cant imagine it being as effective as it would be impossible(ithink) to get it inside the rockwool. Would definitely help if put on the edges, but it comes on rice so it would be hard to innoculate the whole block.

Is Met52 organic?
It appears to be, in that its a fungus. Not sure they produce it by 100% organic means, as its not labeled organic. Sometimes companies dont want to deal with the certification process.
RanchoDeluxe,
I'm pretty sure it is not labeled for food crops, but as inreplyavalon said, that may be because of the hassle, delay and cost of getting it labeled for food crops. It's possible tht they are going thru that procedure as we speak.
Botanigard is labeled for food crops, and it is available in an OMRI labeled version.

I bought the 22WP, but will order the Mycotrol liq next time. Easier to deal with. No dust to breath. You know how paranoid we organic guys are. I've kept the RmofoA's at bay for 7 weeks with 3 apps so far of it., along with 2 apps of nematodes. Will drench with Botanigard approx every 2 weeks till flush. First time I dipped the growbag, medium/roots in it for 15 mins. Next two apps I watered with it. So far so good. Good luck. -granger

I have a couple plants with Met52 inoculated soil - one being my GSC mom - I haven't had plants this healthy in I don't know how long. The GSC was never dunked in Orthene like all the others - as it was a new addition to the garden and went almost directly into the inoculated soil - nothing moving in this dirt for nearly two months now....knock on wood.

jumped on the met train and thinkin ready to jump right back off. dont want to put this stuff down because it does kill root aphids, but the ladies were doing much better with the aphids. had a hell of time narrowing it down to the met too.
there is a mixed bag of plants that have/dont have met and plants that didnt are much more healthy, even with aphids. The met causes slow growth, yellow new growth, and crap roots. No aphids but crap plants. Think im gonna switch to a combo of merit 75 in veg and caps packs throughout flower. Thought this stuff was the magic bullet but in this case it was too good to be true. what sux is dunno whether to run this stuff or not cause if previously incoulated met soil meets new soil it could ruin the new soil. Not trying to get anyone off the stuff but def test it before you go all out, peace and if anyone else experienced this problem please let me know
this was purchased from rogue farmers and used at the recommended dosage of 6 grams per gallon of soil. Used in organic soil. whats even weirder is havent seen one bad report on the stuff hence going all out.

I'd bet a whole bunch that you got yourself another issue. Maybe another pest, or maybe some pythium or something. I have always used at least twice that much met, consistently been pulling large yields with many different strains. You admitted to being the only one that has reported anything like this, maybe you should consider it is something else causing the problems. Just sayin', good luck with whatever is the issue...
Yumbolt,
After you kill the RA's, the plants will have to regrow their roots before you see improvement. I would use Hygrozyme or similar and a good root stimulator like Roots Excelurator for a few feedings/waterings. And inoculate with EWC ACT or a product like Great White or similar. Also, you will see no improvement in the damaged leaves. Healthy new growth is what you're looking for. Good luck, and keep us informed about your progress. -granger

puff adder, I have used eagel 20 with met and it works well together. Floramite works well with met. The liquid met can be used instead of floramite and you will get the same results without using harmeful pesticides.
From my experience met works best with soil or coco. If using it on rockwool then apply at the top then press several grams up through the bottom. Dont forget to treat every few weeks for possible fliers. A pyrethium bomb will work( or met liquid).
Make sure to treat any extra plants or bushes around your grow area including outside the room. You may erradicate from your garden but they will come back from a nearby source.
Preventive is the key with Met. Ive been getting cheap met from a source out of Co. 214.335.9496. They will ship anywhere.
If you can treat your coco/soil with met a couple of weeks before transplant then it will give the fungus more time to grow and become a larger barrier against RA's. No need to wet medium before mixing. 2-4 grams per gal, should do the trick but ive heard of people using double the rate with no sighns of harming the plant. Good Luck!

Met Liquids for foliar use only. talKed to the folks that make the stuff. useless for root aphids from what i gather.

I don't wanna bother all you Growers in the whole world with my minor problems, but maybe there is somebody who was able to purchase met52 in Switzerland or in a shop that delivers to Switzerland?
I would highly appreciate somebody helping me.

HydrodreamsJust received my 1 kg [2.2 lb.] vacuum pack of Met52 rice granules with exp. date from Green Mtn. Harvest 214 335-9496 for $111.86 incl. shipping.
I'll be throwing out my old coco medium, mixing new, and amending with MET 52. It IS labeled for food crops. WOOHOO! I seldom use exclamation points. Also taking multiple eradication measures in my room.
I've been able to successfully control Root mofo Aphids with Botanigard, Nematodes, Azasol, Cedarcide PCO Choice, but this will be labor saving and will cost less. I plan to use todes during 12/12, and will spray once at beginning of 12/12 with Azasol.
I'll report on progress of next run. I'm trying to control my optimism.
BTW, I talked to the guy at the above number about the liquid. They're recommending the liquid for foliar only, mainly because they aren't confident that users will apply it properly. To do that, you need to soak [immerse] them in the liquid for 30 min.+ to get the ENTIRE medium wet. Many RA's chill just under the base of the plant where they aren't likely to get a dose of the MET unless the plants are soaked with entire root ball under water/MET level for 30 min. Looks to me like a good method to treat the dreaded rock wool or to treat established plants, already in medium.
Good luck all. -granger

I have the Met52 EC (liquid) and granular. And a fresh dose of Caps Packs...
The liquid is suppose to mix well with water. it dosent. I contacted the rep and he contacted the factory.
here's the rules:
leave the met out over night to warm up to at least 70 f.
A silicone base surficant is recamended - they have a list of products in prefered order.
After 2 treatments - I'm still finding R/A's in my rockwool.
I have inocculated about 10 gallons of soil with 2 ounces of the granular Met52 - I will run the soil as plan B.
Lotsa Snake Oil, few cures.

grunt,
Nematodes work well. In medium, MET 52 is active about a year, they say. That's provided the medium is kept moist. The date on the bag I just received is June 29, 2013. Mfgr. says that after the exp date, it is still good, but the number of viable spores starts declining. Good luck. -granger
