Thrips Citric Acid

[Avering]

Hello. I have a thrips infestation. I found out about citric acid and have just sprayed it on all my plants, at a ratio of 3tsp per quart. I got some on the buds of the more mature plants, and have all my tents open with a drum fan blowing wind at them. Do I need to wash the citric acid off with plain water? Thanks yall

rip id toss honestly. i would take cuts of my favourite plants and submerge them in spinosad and move those to an isolation area with an aeroponic cloner as some thirps lay eggs in the soil eliminating the media is helpful when attempting to nuke an infestation. if you dont plan on tossing id suggest a bug bomb to kill all that are crawling on the plants and i cant think of the proper word for it but the earth that has the microscopic fossils from the seabed crushed up that the thrips die when they crawl through you would need that to prevent the young from crawling from the soil after being born onto your plant. this looks to far gone to me though. also citric acid wont do much for an infestation that far gone might as well be peeing into the wind

Damn. This was honestly the most infected leaf that I took a picture of. The other plants had one or two that I saw. Diatomaceous earth I believe is what you’re talking about? I can grab some of that. How bad can these thrips affect the bud?

hard to say, outdoors they have natural predators so they dont get that bad generally speaking. say you have some thirps and you cut your outdoor plants down and hang them in the garage you will see the thirps crawling on the floor leaving the plant as there looking for another plant to eat as that one is now dead when its drying. infestations get worse as time progresses as more of them are born. its like if i gave you a penny today and you doubled the amount you had every day after. it will get progressively worse. save yourself the cost of electricity and nutrients cut a few clones and submerge them in spinosad for a minute and then rinse with water and put them in a cloner and start over itll take a few weeks to get roots in the cloner thatll give you time to toss everything and properly sanitize all your tents and containers and whatnot. you should also be asking yourself how they got in there. i used to have a table for clones at one time and i kept getting thirps where my clone table was but not in the main room. turned out they were traveling on peoples shoes that were placed on the ductwork on the floor above and getting through a crack where the vent was it was an easy fix sealing the ductwork above the table. another time i got thirps they travelled on my clothes from a fresh christmas tree i brought in the house. they can also travel on your pet friends fur. anywho goodluck.

Wow. I already ordered amblyseius cucumeris predatory mites. The plants don’t look so bad, I looked at them again and there were just a few I could see and I smushed them. I know there may be larvae in the soil but my earthworm castings also had hypoaspis mites in it. I’m gonna order some more ewc and possibly some of those mites although they usually come in the castings. They definitely got here from using outdoor mulch and soil.

I've had thrips the last couple of grows. A healthy plant with a complete plant food can grow fine with thrips. It's an irritating nuance but not the end of the world IMO. Running potassium silicate at 30ppm+ residual really helps to keep the numbers down. Humic/Kelp mix is another great additive that adds a lot of good trace minerals, vitamins, plant growth regulators and chelators.

If you do all the necessaries the situation should be kept under control and even get better. I had more thrips at the start of flower compared to at the end, but I also pushed silicate all the way through flower but no foliar sprays.

I do citric acid 300mg per liter of water and 3ml unscented dish soap followed by potassium silicate at 1.0 EC with 3ml of unscented dish soap as foliar spray.

ISO alcohol sprays with 2 parts water and one part alcohol also works well. Sometimes I combine ISO alcohol with the other ingredients but only do that with cation. Always spray on small patches when trying out new formulas!

The dish soap is essential, without of soap or wetting agent the hairs on insects work against surface tension, like springtails walking on water, a few drops of wetting agent and they fall straight through the water surface.

Thanks, I needed some hope that this can be dealt with. When you say running potassium silicate at 30ppm+ residual, what does that mean? How much of the potassium silicate per gallon of water? I have some kelp meal from down to earth. Could this be a good top dress ?

I’m sorry, I don’t understand what what the dish soap is for? I thought dish soap was a good way to kill certain pests, we use it on our dog to kill fleas. I also read it helps out for hydrophobic soil. When you say they fall through the surface do you mean they drown?

 

[Avering]

Are these the hypoaspis mites? They’re walking all over my soil

Sorry, yes they drown, the dish soap kinda makes water more watery or less viscosity something about positive and negative attractions in water/fluids.

Are you drunk tonight? just asking for a friend

These little mites made up a ball I like to think they’re forming an army to take down the thrips

That's called on orgy ball

 

[sdd420]

I use beneficial mites but they are expensive

 

[HydoDan]

The dish soap acts as a surfactant.. I use just a drop of Dawn.. Try not to spray the buds if possible..

 

[Avering]

Yes they are. I’m kinda kicking myself in the ass for buying them cause I know I’m gonna have to let them go in the backyard (the instructions say they shouldn’t be kept more than 24 hours) and you don’t need but a puny fraction of the amount you receive. On the bright side maybe they will stick around and benefit my vegetables and trees. Went with orios insydiosis ,amblyseius cucumeris, beneficial hb and sc nematodes as well cause we have a bit of a flea problem with my dog

If you add say ~50ppm or 0.1 EC potassium silicate that equate to about 35ppm residual Silicate(Si) and 15ppm residual Potassium(K).

I recommend to go the humic acid/kelp route with a mix of 5:2 ratio, 5 parts humic acid to 2 parts kelp extract for better effect and to keep dosage and concentration down.

You want the trace minerals, vitamins, pgrs and chelators but not adding excess potassium that comes from kelp. You get the concentration down(K) by mixing both and also better synergistic effects, both plant and wallet will thank you.

 

[Hollatchaboy]

A better, organic, wetting agent would be either yucca or aloe extract. Citric acid has worked well for me, but i have a pretty good ipm going.

I have been squishing them by pressing the leaves between thumb and forefinger where I see them. They're easy to spot under the light once you know what to look for, especially when they see that giant thumb bearing down and scurry lol. I do this three times a day and have only five medium size plants in week 6 of flower in a 4x4 so it's manageable for the most part, but I know I am slowly fighting a losing battle.

Search 'Thrips' on here and after some poking around found this. Dr. Zymes ... I think I'll order a bottle this week....

Sulfur was Magic against Russet and Broad Mites but Thrips seem to be surviving it?

What is the best Knock Down for Thrips??? Luckily they are spreading very very slowly maybe because I grow in L.E.C.a. Hydroton Expanded Clay etc.... But I have like lots of possibilties, Neem being the one I would prefer to use the least since it is the least Compatable with my Sulfur...
