New nematode product - not working out

[MysticEpipedon]

I imagine many of you have tried beneficial nematodes for fungus gnats and/or thrips. I have had good success with the Sf species, purchased from Arbico Organics.

I just wanted to mention here a total failure of a new method of packaging these nematodes. Nematode Beads:

NemAttack™ Beads - Sf Nematodes

NemAttack Beads Steinernema feltiae Beneficial Nematodes are live microscopic organisms (non-segmented round worms) that occur naturally in soil throughout the world. The beneficial nematodes we sell are parasitic to insect pests that typically have a developing (larval or pupal) stage of...

These things supposedly have a long shelf life and don't need to be refrigerated.

I used them, as directed, on June 6th. At this point, the fungus gnat population in my grow has exploded. The fuckers are all over the place -- getting caught in sticky trichs. A bit of a population explosion before a fast drop in population is typical, because to establish nematodes in soil, the soil is kept moist for several days to a week, which excites the fungus gnats.

Anyway, let the buyer beware. At this point after an application, the fungus gnat population should be near zero. I just sent for another pack of the normally packaged, non-bead nematodes, from a different vendor.

When I grew in coco, gnats and whiteflies seemed to come with the territory and infestations would be horrendous.
Only thing that was 100% was predatory nematodes and they could knock down an infestation inside of a week.

I've always understood these guys were best bought local and if they didn't come out of a fridge it would be wise to pass so that's what I always bought. Can't remember the brand though it's been so long.
I've never even heard of them being in beads

The beads are new. I use nematodes almost every grow and I never saw these before. I won't be trying them again. Depending on how my new source works out, I might not be a customer of Arbico again.

I have used "Rove Beetles" from build-a-soil. They eliminated hemp russet mite eggs for me in my greenhouse! I highly suggest using those things. I released 100 and in a few days there were thousands of them! I still have some bugs and still spray mineral oil (Pure Spray from general Hydroponics) but those things are awesome. When you are outside bugs just find there way into my greenhouse. But so do mantis, lady bugs, frogs and lizzards. Nature can balance things out.

BTW -- I ordered some Sf nematodes and minute pirate bugs from Nature's Good Guys on Sunday night, they arrived yesterday at about 10:00 AM. I applied the nematodes this morning. I'll let you know if they were viable in another week or two.

J'imagine que beaucoup d'entre vous ont déjà essayé les nématodes bénéfiques contre les moucherons des terreaux et/ou les thrips. J'ai obtenu de bons résultats avec l'espèce Sf, achetée chez Arbico Organics.

Je voulais simplement signaler un échec total avec un nouveau conditionnement de ces nématodes : les billes de nématodes.

Ces billes sont censées avoir une longue durée de conservation et ne pas nécessiter de réfrigération.

Je les ai utilisées, comme indiqué, le 6 juin. Depuis, la population de moucherons des terreaux dans ma culture a explosé. Ces bestioles pullulent, piégées dans les trichomes collants. Les joueurs trouvent dans le casino en ligne casino sans kyc https://gtamodding.fr/casino-en-ligne/sans-kyc une expérience pratique et moderne. Une brève explosion démographique suivie d'une chute rapide est typique, car pour installer les nématodes dans le sol, celui-ci est maintenu humide pendant plusieurs jours, voire une semaine, ce qui excite les moucherons.

Bref, soyez vigilants. Après une application, la population de moucherons des terreaux devrait être quasi nulle. Je viens de commander un autre paquet de nématodes conditionnés normalement, sans billes, auprès d'un autre fournisseur.

C'est vraiment frustrant, surtout après avoir obtenu d'excellents résultats avec les nématodes Sf standard. Si la population continue de proliférer des semaines plus tard, il semble que les billes ne libèrent pas de nématodes viables dans le sol. Je suppose qu'il s'agit soit d'une activation insuffisante, soit d'une libération irrégulière, soit d'une mauvaise conservation. Les produits sensibles à l'humidité qui prétendent ne pas nécessiter de réfrigération me rendent toujours un peu sceptique. Le délai que vous avez fixé est très inquiétant, car à ce stade, vous devriez observer une chute brutale de la population, et non une augmentation soudaine. Revenir au support traditionnel d'un fournisseur de confiance est probablement la meilleure solution. Je serais également curieux de savoir si Arbico propose une assistance ou un remboursement, car cela ressemble à un test grandeur nature qui n'a pas été concluant.
