A few of my seedlings are getting some strange growth that seems consistent with broad mite infestation. Is there a product that you recommend for these pests? In the meantime is there anything I can do with household items like dish soap?

Do you need help identifying a 🌶?
Is your plant suffering from an unknown issue? 🤧
Then ask in Identification and Diagnosis.
I think I may have a broad mite problem

Azamax takes a long time and needs stupidly high doses to kill these things. I use dry sufur fungicide because it needs one application and then a couple more just to get any stragglers.
Edit: If plants are really small and can fit in the bathtub or a bucket, submerging them for about half an hour in warm to mildly hot water will also kill the mites.

Soaking the plant did not work. It floated. Once I tried to push it down all the soil came out of the planter. It was a big mess
NO. That is just not true. 1 TBSP per gallon takes no more than 2 applications, max. And it can be stored, so there is no waste. It starts working almost immediately. And further, it causes reproductive issues in the ones that aren't killed.
I'm not a fan of using any manner of pesticide, if I can help it, but I also can't agree with your comment.
Please be civil. Im just looking for help.
I just know how these things start...
Anywho... Here's a pic of my problem plants:

Have you ever actually dealt with broad mites before? Because it takes a lot of neem applied on a strict schedule for long term in order to actually get rid of them. Sulfur dust only needs one application with any future ones being just to make sure. And I wasn't using "literally" incorrectly because you're the only person I've ever seen who claims that neem works on the first application.solid7 said:
That doesn't look like broad mites to me. And ive experienced a lot of mite action.
Broad mite damage includes a drastic downward curling that is sometimes referred to as " clawing ".
Neither pic shows that action taking place. The pic on the left shows upward crinkling of the leaves. Which could be indicative of a few things. The crinkling could be a sign of edema, excessive water, but the combination of crinkling with the upwards cupping makes me think soil pH. Why? Because I have the same issue and a well respected grower told me to check my soil pH instead of what I thought it was which was calcium deficiency.
Take it or leave it, just my .02

get a 50x+ lens to diagnose the problem correctly before applying any corrective measures.
I've never had success controlling mites with any neem based products. I resorted to spraying with Oberon two years ago when mites devastated my entire crop. YMMV.

To throw in to the mix, based on what sirex said... That is also what it looks like when your plants run out of food.Jeffcontonio said:I just know how these things start...

Calcium deficiency can be mimicked/caused (depending on how you choose to look at it) by overwatering. PH swings can prevent proper utilization of calcium. And certainly calcium deficiency, itself, and outright, can look like this. Also, environmental stress can look like this. Too much sun, sudden temperature swings, etc. All can be similar. Slurry test will help decide the PH problem. What are you feeding, and how often?
You "literally" can't tell me that "literally everyone disagrees with" me, simply because I'm the only person that you, personally, have ever seen make such a claim. That's "literally" an incorrect application of a term.cruzzfish said:
But, to the bigger point - I had a problem with broad mites last summer. First time, I used predatory mites. Second time, I used Neem and peppermint soap, as I mentioned. It literally took me 2 applications to get it under control. (4-6 days between application, can't remember) I can't say what has worked for literally everyone else, because I literally don't know everyone else.
There are tons of micro spots under the leaves as well, which leads me to believe it's a pest issue.
These are very small seedlings only a few inches tall, in a 4" pot.
I bought a bunch of end of season plugs for $1 each from Jim Duffy and most of them are dead or dying. The leaves have all fallen off covered in spots shriveled and rusty looking.
The ones I have grown from seeds are much healthier but some are starting to show some similar signs.
