Spider mites AKA The Borg

[CannaRed]

I noticed that some outdoor plants had white mite markings on the leaves on the branches closest to the ground. But these spotting patterns are different from the patterns I have seen on my indoor crop. The spots are more grouped together, as opposed to spread evenly over the leaf surface. I should have grabbed a pic.

I cut off the lower branches and treated with karanja oil, and extra aza with Transport. When using Transport directions say to only use 1/4 of normal amount of bio-pesticides.

Since I started using Transport along with my normal ipm sprays, I have been mite free inside.

Has anyone used Coot's cilantro tea spray?

A couple of years ago I used it a few times and decided to grow cilantro as a companion plant. I figured if cilantro tea repelled them so would the plant.

Wrong!. It was spider mite magnet. The mites were on the cilantro more than the cannabis.

Not to the point where they completely left the cannabis though. That would have been cool. Put a cilantro plant in for a week collect the mites and then remove the cilantro from the grow. But didn't work as smoothly as hoped.

I mentioned a cilantro tea spray to a indoor aquaponic culinary herb grower. He said "that's odd, my cilantro is always the first herb to get mites."

How long do they stay dormant for; if they don't have a food source?

 

[earthwyrms]

i have just read that they can hide in the walls and go dormant,


i found one walking across my tablet/computer screen,


i am in the same room as my plants


i now can't risk spteading it to anyone. anyone i meet is at risk


therex alot of stuff in y room.


i thing i got them for life, nomatter where i move or what i do


the fungal control options seem to clear all tne predatory mites bit not nearly all the plant eating ones .


i guess regular foilar sprays are all i can do. they haven't made a genetic eradicator yet.

Mammoth P company has a new product for crawlers....It uses Thyme..so you might look into Thyme to help with the mites situation..DJXX

 

[Zeez]

It's likely that the ones coming from the grow shop are going to be the toughest ones to get rid of. They have already had all kinds of remedies tried on them.

i just bleached the leaf litter and floor and removed it and other stuff and used an isopropyl alcohol concoction; i got some on the bleach and chloroform and phosgene were created. i had done this crap before. it was bad, my lungs are recovering.



BUT anyway, now that i got the place cleaner, i'm more ready to move and keep on top of things constantly.



THE CONCOCTION was

about

•a capfull of McCormac thyme

•a cap and a third of their ground clove

•a cap and a third of their ground allspice

•a cap and a third of pepper corns and then also a cap of ground black pepper (the pepper corns were not ground totally so after they were left in the funnel, i put them back in the blender with a cap of garlic powder and more isopropyl alcohol)

•a cap of garlic powder

•and about 3.5 caps or 6-7ml of Imada Red Flower oil which is

Camphor- 7%
Methyl Salicylate- 15%

and the rest is Lavender Oil , Turpentine oil, Safflower (oil, presumably) and Liquid Paraffin

•this was in about one full 32oz bottle of 91% isopropyl alcohol which sealed tight and blended in a "magic bullet" blender

•there was also added about 5, 6 or 7 ml of australian sandlewood oil that i had left in (maybe 100ml ) isopripyl alcohol

(the papers i posted say that it kills the eggs. rosemary wasn't very effective in the paper )

•i also added 5 clementine orange peels which i half ass sterilized for a few minutes in boiling water with a coffee cup over it (also filed with water). i didn't want any fungus making it along with the solution . idk if it was neccessary, but it is what i did.

•i also added a handfull of walnuts ( it wasn't the shelled type or had the black ink part of the fruit, but i wanted to try it anyway)


•and about a Tablespoon of mustard powder for the allyl isothiocyanate (i didn't have wasabi powder)

•also there was about 1-1.5-1 2/3 teaspoon of lemon and lime juice. I think the lime was about 1/3 of the total...

so 2/3 to 1 1/9 teaspoon lemon and 1/3 to 5/9 teaspoon lime

Or whatever


•Oh and about a half cap of cinnamon. All these caps were the small cap kind exept the cinnamon, so it's like one small cap of cinnamon. The pepper corns were a kind of medium cap and weren't from McCormac (neither was the garlic powder but it wasbthe same size cap. And also, the "cap for the Imada Red Flower oil was just an estimation of the cap size it had. I just splashed it in and tried to give a ml amount too)



So that's what i did, and i tryed filtering it through underwear and stff after it soaked for an hour. And i lost some an about filled the 32 oz isopripyl alcohol bottle up till the first notch, i then added water up to the tippy top so it was about 70% iso conc and added 2 drops dish detergent.



then i sprayed all my plants thoroughly and left them in darkness for maybe an hour. Then i rinsed them off with the same pump sprayer with water.

my room smells great. My plants look alright, exept the ones in the planter. They weren't immediately watered before hand and i also was rough with the sprayer when trying to get under them, and i broke some leaves and tops. They seemed soaked and soggy and droopy, so i trimmed off the parts i messed up and after rinsing and a good watering , shook them off.

The cuttings in the Oxycloner looks great, likely due to being hydrated beforehand and through the process. so, whoops






ANDddddd..... theyr'e dead
the clones have a few that have alright parts but are weighed dwon by the wilted dying leaves and are on large stems. they won't likely make it. i left them that night without light, so that could be it.


sorry

How come nobody's talking about Lady-bugs ?

They do a pretty thorough job.

When I used a soap, it was a Safer's dip-tank. (15 gallons normal strength mixed from concentrate.)

I don't like to use soaps after 4 weeks. Would rather smoke crispy critters than safer's residue.

 

[zachrockbadenof]

How come nobody's talking about Lady-bugs ?

they never worked for me... only thing that keeps em somewhat at bay , is spraying various nasty's until a week into flowering... after that, i spray the plants with water - i hate the borg...

 

[earthwyrms]

i'd love to use ladybugs but my out-take fan would chop them up (so i would have to put mesh filter, like copper or sink sctubbers , over it) and i would have to do the same to my passive intakes so they don't crawl on me in my room/place/sleep



but also they only manage rather than exterminate.


i think the mites have spread across my bedroom (or a person's house) and are underneath objects and in any nook or cranny. Or behind the walls and electrical outlets like some people said or suggested.




i just took out my waterproof shell for the tablet i am using. it was under somethings stacked along the wall my bed is against.


i was just reading this article
https://getpocket.com/explore/item/...ly-dark-energy-stars?utm_source=pocket-newtab

check it out !


When i saw a mite crawling on the screen. i wasn't inside my room either.




For outside it seems a good idea, especially if you can plant some companion plants or something that help keep the lady bugs around (i don't know if that is how it works, but some people say they cannot make them stay in their garden. Maybe shaded areas help)




But for inside, i'm thinking of cypermethrin and dinitofuran ( https://www.domyown.com/alpine-flea-insecticide-with-igr-aerosol-p-1886.html with Dinotefuran 0.25%, Prallethrin 0.05%, Pyriproxyfen 0.1%)


For myself. It looks like these fuckers are hitching a ride whereveri move and i have to. I even ended up with fleas (i think they are cat fleas not human fleas, but the larvae eat plant detritus). i fucking hate nature. it probably came from my aunt's dog which passed it onto my grandpa or his dog, which got on me or in ny room. i don't have any more plants. exept a mulberry tree-ling and two containers with cacti, so at this stage, i hope i can throw that stuff at them. Obviously, if i had plants in flower it would be a problem. But it would seem the issue for indoors (besides management of the outdoor breeding area of infection) is really saving clones (vegetative) and keeping rooms/houses purified (i don't know if this will ever happen) so the genes don't die . That at least seems to be what i am facing. i lost the mothers, and they would have been infected in flower unless i maybe soaked them once or twice a day, it seems the bugs and eggs and their nasty smell would make it into all the cured bud and maybe even bubble hash. Nasty. Forget about sharing clones; maybe with a glovebox and chemical treatment and sterile transfer to sealed packaging, or tissue culture. Just seed maybe

I am resigned to a constant battle. I live in deep woods and am using neem regularly both inside and out along with the vinegar dip and no pest strips indoor. Neem every three days till flowering starts then a pyrethrum TR bomb inside. Outside in past years the local true bugs have kept them down but I have a new spot this year and they are needing help. I guess I have normal non immune variety since neem kills them. I waited too long to treat outside and now my headband has all kinds of eggs to follow up on. My bangi haze usually gets them first but not so much this yr. They get less N could that be it? Following Dubis advice on bangi letting them be lighter green.
Does anyone know about nutes balance and mites?
Could it be too much K?

 

[earthwyrms]

the "mite eradicator" is supposed to kill the eggs too. it just needs to be at dusk and after watering, and well hosed off after 20 min. (The post says , water 30 min prior, and spray witg lights off and let sit 20 min before rinsing well). it's just baking soda, apple cider vinegar, epsom salt, lemon juice, and 2 drops dish liquid, in water. the specific recipe is on the forum thread "mite eradicator" but i can post it here.
rosemary wasn't found effective in the papers i posted.








the sandlewood oil (in a light concentration should help and also prevent as much egg laying. i don't know it if kills eggs. it would be googleable though). i posted a paper about it. i used to much but the paper mentions killing in the high 80s percentile). Combined with the neem, i guess it would be effective. i guess a little wood (had to do it) go a long way and 16 oz australian sandlewood oil (sustainable) is 60 bucks including shipping, on ebay.








HERE's DATA to fight the borg




first off, some of the most relavent quotes . Also TSSM means Two Spotted Spider Mite

" However, the mortality caused by treatment with sandalwood oil (89.4%) was highest, followed by that from common thyme oil (62.8%). In addition, the total number of eggs laid was lowest on the leaf disk dipped in the sandalwood oil solution. The number of eggs per live adult did not differ between oil treatments."


AND

"Mortality of the sandalwood oil treatment was higher and total number of eggs of the treatment was lower than that of common thyme oil. Mortality and the total number of eggs laid by TSSM adults treated with sandalwood oil in the 2nd trial were similar to those of the 1st trial. However, the effectiveness of common thyme oil decreased dramatically between the first and second experiments and did not cause any substantial mortality relative to the two controls."





an article on sandlewood oil
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3215870/

that shows
“
Results

Acaricidal activity of essential oils

Mortality due to treatment with 34 essential oils and the number of eggs laid by the females treated with those oils did not differ significantly (P < 0.05) from the control (2.9%), although it approached significance (P = 0.0588) (Table 2). However, the mortality caused by treatment with sandalwood oil (89.4%) was highest, followed by that from common thyme oil (62.8%). In addition, the total number of eggs laid was lowest on the leaf disk dipped in the sandalwood oil solution. The number of eggs per live adult did not differ between oil treatments.

Because sandalwood and common thyme oil produced higher TSSM mortality compared with other oils, the acaricidal activities of the two oils were retested. Sandalwood oil was significantly more effective than common thyme oil and the two controls (0.0 and 1.1%) (Table 3). Mortality of the sandalwood oil treatment was higher and total number of eggs of the treatment was lower than that of common thyme oil. Mortality and the total number of eggs laid by TSSM adults treated with sandalwood oil in the 2nd trial were similar to those of the 1st trial. However, the effectiveness of common thyme oil decreased dramatically between the first and second experiments and did not cause any substantial mortality relative to the two controls.

i also found a page on how to choose types of predatory mites
https://greenmethods.com/persimilis/

and do’s and don’ts of use of dormant oils
https://hyg.ipm.illinois.edu/pastpest/200520f.html






Also the oil go's a long way



200 μl of each essential oil or santalol was dissolved in 20 ml ethanol (97%, Burdik and Jackson, USA), and then mixed with 180 ml distilled water to give a 0.1% essential oil solution. Triton X-100 (0.009%) was added to the diluted solution.



so that would be 4ml in 400ml ethanol (isopropyl should work , i think) and 3.6 Liters water (that's about a gallon), with 3-4 drops dish detergent.


Triton X-100 is just a phase transfer agent for oils and water liquids. Some dish detergent should do it.



the iso would end up costing more than the sandlewood oil, i think. Denatured alcohol would be fine, if that is really really cheap.
Couldn't hurt to use extra oil too, maybe double it . idk




i used way too much
doh !

 

[azad]

Has anyone tried the Green cleaner spider mite product yet.,
Also a new chemical fluxametamide seems to be worthwhile testing.
Nissan Chemical Corporation has announced the completion of a facility for manufacturing fluxametamide technical, for its new insecticide Gracia (development code: NC-515) atits Onoda Plant (Sanyo-Onoda, Yamaguchi).

The development of Gracia is highlighted as one of the most important projects in the company's Agricultural Chemicals Division, in the medium-term business plan Vista2021 initiated in 2016. Gracia will be launched in Korea in 2018, and Japan in 2019. The characteristics of Gracia include efficacy against a very broad spectrum of important pests, while demonstrating less impact on pollinator insects such as honey bees.

thanks

@Azad
I just picked up the green cleaner last month. It killed every mite it hit and I haven't seen any emerging from eggs for 10 days. I used 1 oz per gallon on headband pineapple express and long bottom leaf with no toxic reaction.
I intend to continue it in rotation with neem and Dr doom. I thought I had seen the last of them till spring when I didn't see any for 10 days before but I had a burst of the little white buggers 3 weeks.before chop.
Anyone burn sulfur??

Whoa, did you make a foliar with all those ingredients or did you marinate a pork loin? Thats the craziest concoction ive heard of. I am all for the organic approach but if your issues w mites remain unresolved, sometimes its worth it to break out the big guns and eliminate the issue for good. Then back to organics. The french call it lute raisonee

Shutting down for a week got rid of my infestation I thought the best way to kill them is to get rid of their food source so I harvest at 8 weeks wait a week for them to die then moved the new crop in no spiders mites to be found they all starved to death good riddance.
It's the best way no food no life

Also a shower to knock off the mites especially if you can use high water pressure like a water hose or you shower head with a jet stream option

PURE CROP 1.........look it up. Very effective product, and is used on entire fields of crops with no harmful effect. Go to the website and read why it’s all together different.

 

[Muarco]

Are these mites?

 

[TheForgotten]

I've probably posted this before but it's always a good refresher....

I live in BC and there are hardy S.mites here, i've got a 100% effective treatment.

Some start by vaccuming up most of the mites/webs.

Safers soap 3 - 4x, once, then again at day 5, day 10, then sometimes at day 15. This interrupts their breeding cycle.
THEN, hang No-Pest strips in your area (easy if you're treating cuttings in domes or growing in a tent/cabinet). This kills all leftover mites (and any other bugs).
They used to be called Vapona, but i believe they are now Ortho (i don't know, i haven't had mites in years, this treatment is completely effective).

Home Depot has Ortho 65 g Home Defense MAX No-Pest Strip
