Grandevo microbial-based insecticide

A good friend of mine mentioned Grandevo and how it's great for mites (including broad mites!). Has anyone tried it before? I'm fixin to get some and spray it right before I flip and 2 weeks later for preventative means.

GRANDEVO® advanced bioinsecticides control a broad spectrum of chewing and sucking insects and mites … but are easy on beneficials. They can be used in rotation or as the foundation product to strengthen integrated pest management programs (IPM) and insect resistance management (IRM) programs for a wide range of fruit, vegetable, and nut crops, as well as turf and ornamentals. Combining high performance with operational flexibility, GRANDEVO bio-based products are paving the way for new, innovative uses of microbial insecticides.
Complex Modes of Action Reduce Risk of Resistance

GRANDEVO is microbial based and is powered by a number of compounds that create complex modes of action, resulting in a potent biopesticide that is highly active against labeled insects and mites. Control of pests is achieved by unique combinations of repellency, oral toxicity, reduced egg hatch, and reduced fecundity (ability of pest to reproduce). With GRANDEVO’s multiple active compounds and complex modes of action the risk of insect resistance is greatly reduced.

The label lists ALL of the bad actors that come with Cannabis growing. Nice find. Do you know of a source?

I wonder if this product would be effective in the prevention and/or elimination of RA's (Phylloxera), in R/W?

I currently inoculate the rockwool with Met 52 Ec and OGBiowar root/foliar packs and am simply crossing my fingers, unaware of how this effort will protect me from root aphids. I'm hoping this will keep me safer than not using anything. I miss the benefits of a H202 sterile environment , down there in the root zone, but refuse to charge forward with no shields against those brutal little bastards.

I felt like I was the Deathstar and phylloxera was Luke Skywalker. David vs. Goliath

So far the liquid Met and the Biowar are working , but the true test is time

Always looking for new , safe , and EFFECTIVE methods to prevent/protect the nightmare I experienced

Look towards neem oil for an extended life span ...your life that is ....lol

I ordered some. Haven't used it yet. I've heard reports that it's effective against broad mites, but also seen a study that it isn't very effective... So I dunno

Can you link that study that found it wasn't effective? Definitely worth looking into

btw, I do not care for neem much at all. And so many people here spray it on their buds, it's just nasty. If "Chromobacterium subtsugae strain PRAA4-1T and spent fermentation media" was used on their buds instead of neem, i bet that it would smoke better and cleaner

Interesting, looks like there are a lot of insecticidal fungi/bacteria available on the market already. Maybe we should make a thread with all the different options?
I have a fungus based insecticide which supposedly only attacks the bad guys. I've used it but dunno how effective it really is, since growing organic I can't say I had a single pest problem... I've a feeling composttea either/both repels insects due to increasing plant resistance and/or by delivering bacteria which attack pests.

I'm all ears!

What I have is called Botanigard ES

Biological insecticide used to control whitefly, thrips, aphids, and many other soft-bodied insects in greenhouse and field crops. Based on the highly successful fungus, Beauveria bassiana, strain GHA, it controls the most troublesome crop pests – even resistant strains. Because of BotaniGard’s superior formulation, higher spore concentration, high viability and proven performance, it outperforms other Beauveria-containing products. When properly applied, BotaniGard’s insect control can equal or exceed that of chemical insecticides.

That's a completely different fungus. I had little to no success with BotaniGard controlling a white fly infestation.

Looks like the Grandevo only comes in 5 lb. bags.

No, I can't remeber exactly where I read it, but I remember it was written in the last year... this was not effective against broad mites mind u. It was a short type study I've seen universities put out where they take a certain number of miticides, some toxic, some not, and after testing them for a period of time, rate the efficacy 1-5. Grandevo got a 1 for broad mites, as opposed to, say, pylon got a score of 5. Now, that's better than having no effect on them, but not great at all. But, grandevo can be used with predators, and can safely be used in flower, so it can definitely have a place in an IPM program. I just decided to go with OG Biowar...

It would make sense that using bacteria works better in an organic environment which isn't hostile to these bacteria. Dunno if they can survive or reproduce in minerally fed environments?
That said, growing organic removes most of the need for pesticides, at least IME. Let nature do its work, predators enough as long as you don't create a hostile environment... It's also noteworthy that plants with low Brix levels get attacked first, and high Brix can give immunity to pests.

What? Yah I'm sure the bacteria cares where the plant gets its nutrients from... let's not turn this into a debate on how much better growing organically is than everything else. Why is it that so many organic growers have a holier-than-tho attitude?

OG Biowar did not significantly affect mites or thrips when I used it at a facility I worked at in 2013-2014

Eh, was going to post the study mentioned above and a few others, but thought to let this play out, and am concious of my frequent ability to respond negatively. It does appear Grandevo is more suited towards targeted pests, and the claims of efficacy as an acaricide are more mild fringe benefit than a sole means of control. I'll post up if I get the desktop going, tablets are a poor substitute.

well that blows

Sorry bud... at least I'm guessing u didn't buy the 5 lb. bag like I did... incidentally if anybody wants a 5 lb. bag of grandevo to try out...

U know I was just thinking, I've seen in the same type of study I mentioned above the miticide Kontos only received a score of 2, and people have reported great results using it as a preventative measure against broad mites. Just a little food for thought on what that score of 1 might mean for grandevo... of course Kontos is a systemic miticide as opposed to an ingestion/stomach poison type one...

This company also makes regalia max which is a great tool for suppressing powdery mildew, but it's quite pink. Grendevo is also supposed to kill beetles and such when I talked to their sales rep a couple years ago.

Bear with me, desktop is still on the fritz. Both links are direct downloads of PDF files. Can't be fucked to figure out how else to link with this half pint 'puter.

It looks like Marrone is overstating Grandevo for the control of mites, broad and TSSM. It is effective against other pest though, and would be handy to have in reserve.
