Thrips how to treat

Hey guys, I have these pain in the ass insects In my grow. I think they are thrips, based on the image so you agree and how do you guys treat these fucks ?

I’ve been using purcrop1 on the girls who are going to be ready in a week or two. It seems to help but hasn’t remedied the issue.

On the younger girls, I’m using Bonide Sulfer. 1.5 table spoon of sulfer mixed down with 4 cups of water. I sprayed yesterday morning, left the light dimmed all the way. This morning when I checked I notice 6 fucking bugs on one of the fan leaves. I killed them all manually however I’m curious if the sulfer even works. This is my second application - I thought it wouldn’t need a second one to begin with but seeing them on the plant after soaking them yesterday is discouraging

would love some help on this one, thanks!

I've used Captain Jack's spinosad. Spray at lights out, top and bottom of leaves, then do it again a few days later. And you should be good to go.

My plants had a lingering infestation and I used all sorts of stuff, but Captain Jacks finally wiped them out.

Appreciate the feedback. Can captain jack be sprayed during flower?

I've heard of people using it pretty deep into flower, but I would stop once buds start forming. Citric acid or nematodes are probably the best choice at that point. I don't know much about nematodes though.

I've used Spinosad directly in bud when I had budworms, didn't hurt anything or affect the taste. But typically thrips just go for the leaves, so you probably wouldn't need to spray the buds if you aren't comfortable with it

I think the issue is that it is a poison. Also how do you only spray the leaves?

Citric acid

It's not a poison, it's a bacteria. Not harmful to humans or animals. Spraying you may get a little on the outside of the buds, but as I mentioned, I've sprayed INTO the buds in the past for budworms

It's not harmful if ingested but I don't believe there are any studies about smoking it.

Fucking little cunts
They lay eggs in the soil so simply spraying the plant only wipes the current adults and in my experience damages your fan leaves edges.

I've battled them a few grows.

Research led me to learn about using beneficial insects. I tried it and will never spray for anything I don't have to again.

done and done.

For thrips, cucumeris predatory mites sachels you hang on the plant. They will eat the thrips and then when none left they eat themselves, they die out within 4 weeks tops.

2ndary is nematodes. These come in tea bags. You put them on top of your soil and water over them into the soil. They are little worms, and when the thrips feed they are ingested, the nematodes then eat them from the inside lol!

You need both as the thrips lay eggs in soil.

I'm currently battling the little cunts this grow too!

They actually lay eggs inside the plant tissue and they hatch and fall into the soil to pupate.
I think some types of thrips can also lay in the soil.

Thrips control
The cucumeris and the scimitus will eat wind blown pollen to stay alive. They say there's enough pollen in the air that when you open your tent enough will blow inside to feed the bugs if there's nothing else for them to eat. The scimitus will also eat spring tails, fungus gnats, and more

Ok I need to get rid of these fuckin' thrips. They came along with root aphids and those I wiped out with imid in the end. I'm using spinosad for the thrips and have some nematodes for the soil.

How often is best for spinosad? I went with every 72, but now I'm seeing these mother fuckers the next day after spraying. Also using Southern Ag "Spreader Sticker".

The only bonus to the bastards is I managed to find a couple plants I want to cull just cause they got fucked up compared to the rest.
Oh another random thing I found out, it looks like thuricide will kill on contact. I swear I managed a good killing when I sprayed that for a week on accident.

I started using alchemist stout msa (silica) I haven’t seen any thrips on my girls since using. I did a few pure crop 1 treatments 4 days straight. It’s been like 2 weeks and I haven’t seen any thrips.

Plus it's all natural.

Yep, you need a good soil drench to kill the eggs and larvae in the soil. Or else the cycle continues.

I used it on a early flowering plant once. Never again. Made all the pistoles turn brown and I was like I ain’t smoking that shit.

I don’t use it now anything past stretch.

Thrips mainly lay eggs in the soft plant material. the leaves. there may be thrips in the soil, they do overwinter in soil and could easily be knocked off by anything. perhaps some overwintering bugs might drop some eggs in soil. but the bugs eat plant material, not soil and not roots like fungus gnats. they drop eggs right into the leaves, so they larvae can just hatch and feed. Thanks for coming to my TED talk

Where did you get the alchemist stout msa? How did you apply it? Thanks
