DEALING WITH THE SPIDERMITES

[MS-13]

Hello everyone! I think one of the most annoying problems for the plants are spiders...
I saw white dots on the leaves about 2 weeks ago. Now few of the plants are allmost white if comparing with the others. (Adding pictures)

As i don't like to spray ant chemicals on the plants, i bought spider mite predators. But it was told to me that they are very active, red colour and should eat all the spiders and their eggs in 24hours.
But i don't think i see any changes.
Ofcourse the problem is that i can't tell if they are the spiders or the predators under the leaves, but i see them walking there...
also i bought DR, SCHIMEL (adding photo)
What do you think if i spray them in 7th week of the flower.
What could bring more stress and cause more damage, the situation with spiders uncontrolled, or the chemicals sprayed on the plants?

Maybe someone have tried the predators? Or this spray?


Thanks a lot for the answers!!!

Well, chemicals on almost finished buds aren't good for you. Spider mites aren't good for the plants.

I use DE, but if you introduced predators, it'll kill them too.

You DO NOT want to let them get any worse.

That's gonna be your call all the way. What's in that bottle?

i would try to make it to the end of this crop without spraying anything. remove the worst leaves and try to manually remove pests from leaves you dont want to remove.

wash the whole harvest in h202/water.

in the future. spray plants in veg and early in flower so you don't have to spray in late flower.

I'm just finishing up a crop that has mites. I thought I had got rid of them before flipping to flower but was wrong. For the first couple weeks of flower I spot sprayed with Safer's Ends All that I added a little neem or canola oil to but couldn't get rid of them all.

All I've been doing is hand killing them to keep their numbers down and use the vacuum to get them where they are most concentrated. I used electrical tape to attach a piece of window screen to the end of the crevice tool on the vac and that gets them quick. A couple more 4 hour trim sessions and this crop is done. Keeping the best buds to cure for smoke but a good portion of the crop will be made into oil. The little buggers are only on the surface of the buds and all that gets trimmed off so the smoking buds are bug free.

Never taking in free plants again as that's where my mites came from over a year ago. Planning to repaint the grow room after removing everything so I can finally clean the buggers out for good.

No more switching to flower until I am 100% certain that the crop is bug free!

Sorry could you explain what is DE?

Diatomaceous earth. Basically, very fine rock powder that cuts those little bastards up when they move across it.

Green cleaner, works great. Like these other guys are saying "Treat immediately"! Once they get out of hand you will need a flame thrower.

You dont want de in this situation.

Pick off the worst leaves or some leaves so you can get a good spray on.
.Get a quality sprayer, one quart of water, 25ml of dish soap (clean, natural), 150ml of rubbing alcohol mix well spray the underside of the leaves mostly but spray everything, repeat every day for a few days since late in flower if this was earlier I would say spray every few days a few times. Dry thoroughly with a fan so you dont get bud rot, meaning have some rocking airflow going on after you spray. Shake the extra water off the branches also its very important to take action after you spray. especially if you have to spray anything in flower more so in late flower.

Probably want to give it at least a week from the last spray to the day you chop without spraying anything //unless its just water which you can spray just water anytime but then again it promotes bud rot.

Might want to do a couple of sprays at the end of just water.

Wouldnt use the Dr. thing myself as I dont know what that is

Always be shaking up the sprayer as you spray.

You do not want to spray your plants with isopropyl anywhere near harvest. It’s a solvent, not a pesticide. It’s gonna dissolve any oils out of the trichromes it hits.

I was just about to say that. Even diluted in water... I wouldn't if saving crop is the name of the game. Alcohol separates from water.

Yeah i kind of forgot about that deleted the post the op could just spray with water to kill the adults, the rubbing alcohol would kill the eggs if in veg

Still dont want to use the dismascous earth for spider mites here.

Why?

Diatomaceous earth. Basically, very fine rock powder that cuts those little bastards up when they move across it.

You never told the new guy how to use this product. Its a fine powder and I didnt want him to try and spray it on plants. ///Its my understanding that it is a top dressing for bugs like fungus gnats or root aphids.

His spider mites are in the leaves.

imo not the right product for what they want to do, waste of money at week 7
Thats why.

What? So you don't even know what it is lol?

First, you don't spray a powder. You sprinkle it on everything in the grow room, including leaves. It kills everything fungus gnat size and smaller. It cuts them up.

It's like $10 for a 2lb bag that will last a LONG time.

Meanwhile, you suggest alcohol on buds...

ok ok ok i retracted my post but your sticking with yours. i would smoke some alcohol sprayed buds but I dont think I want to smoke anything with dismascous earth on it .Including leaves.

I dont want that shit in my lungs cutting up my lungs and I wouldnt want to sprinkle that shit on everything in my growroom, and I suggest that the op doesnt do it either. 3rd monkey I dont care to get in a tift with you but dusting everything with DE is not a good idea imo for spidermites, they live mostly underneath the leaves how are you going to dust that.

and yes I know what it is I just dont like to be a know it all cause I dont know what everything is all the time

Im out later.

My worst nightmare!! I had them for about 4 runs! Couldn't get rid of them. Once they are on your plants..... good luck! I tried all different sprays and read all the home remedies and nothing killed them. The best thing I used was a neem oil spray. Kept them at bay for sure but when i thought id beaten them a week later they were multiplying again!! Want to know how I got rid of them? I finished my perpetual harvest out, (keeping no clones at all) used a bleach/water solution and sprayed the floor, walls, all my equipment, washed my carbon filter pre filters in this solution, EVERYTHING!! Remove any dead leaves so you have removed their food source. I used this opportunity to go for a 4 week holiday!! And started fresh from seed. Really slowed me down but haven't had a problem since. I try and keep my grow rooms as sterile, clean and dead leaf free as i can now. You just gave me some bad flashbacks! Thanks MS-13! Haha. Good luck man.........

op dont use a neem oil spray this late in the grow.

a spray like mighty wash works or grean cleaner but that has alcohol in it. Just plain water kills the adults might want to try that every few days till you can kill most of them if you want the best bud you can get at this point. Shake the branches off and have a lot of air moving after you spray so you dont try and get bud rot. Spraying constantly is what I found out works best, ,meaning monitor your grow and dont be lazy.

Thanks Bernie! And I thought the alcohol was used in the separation process? It is advised to not pick fruit within 1 day of using a neem oil spray. So surely must be pretty mild!? I've found neem oil to be one of the more natural, plant stress free sprays (in my experience) but yes I definitely agree with you, dont spray it or any pesticides on your plants at week 7! After all, who really knows what's in any of the sprays we use!!? But honestly, prevention is key! And keep animals (cats, dogs etc) out of your grow room/s

There's no tift, I would just stop replying before that happened. I have no desire to argue.

I will say this though... DE works. 5 days, everything dies. Underneath leaves, you can mix with water and spray. It'll stick and dry and do what it does. Buds can be washed and the powder vacuumed up.

Mites suck and they are the real enemy, not you or I. For me, I do what it takes to get them gone. It's 100% effective, 100% of the time.

For the record, I don't know everything either. It's not about what you or I don't know, it's about what we do know. The rest, we learn.

 

[Hydro4life]

Maybe this could also be used only in veg to cut off there cycle if doing perpetual runs rather than what i had to do! Maybe once flowered plants are finished remove them, clean EVERYTHING with bleack/water solution. Wait a couple of days then wash treated vegged plants with pure water and put in flower room? Just a thought... hmmm DE......

Meanwhile, you post false information. DE does not cut up spider mites. It has a desiccant mode of action, meaning it drys out there outer waxy layer, making it impossible for the mite to control its fluid level.

Let’s make sure what we are posting is truely factual.
