I went to check availability and possibly buy earlier than usual the few hybrids I grow (mainly peppers and cucumbers) . My go-to seller has been Harris Seeds for the past few years, no reason just it is like a favorite pair of worn shoes and sometimes has a shipping deal. Pretty mainstream selection but they carry AAS.

The peppers I had run out of were now only sold as treated seeds. I noticed it was a trend among whatever random things I was looking at, either treated or organic seeds as the only options. To be clear, they are treated and not pelleted I believe. In the past their treated seeds have had strange color coatings, but I was able to get more than one year from the packet.

Have you seen this trending with other companies? Thoughts on treated seeds, good or bad for longevity or germination.

Yes I have seen this lately. It does bother me to receive turquoise colored seeds. I myself have not used them because the color scares me so... I just went and ordered the same seeds from somewhere else. The treated seeds are sitting in a drawer now I wonder if they will keep longer.

Color is probably just a dye, to indicate that seeds have been treated, most likely with Thiram

The vast majority of treated seed that I see comes from Harris, with little from elsewhere. I handle with care, and have no worries.

I have once or twice received treated seeds from a supplier, even though I specified no treated seeds. Could never bring myself to plant those.

Here is an overview of publications about thiram:

here's what was published in the 1950's about effects on the microbiome and persistence in different soil types:

And here's a recent article on its persistent genotoxic effects in mice:

Read elsewhere it is hepatoxic (poisons your liver)
Ahhh, why do I even bother to read this stuff? It's never the kind of thing to change my 'no poison' policy.

OTOH I just learned it's being sprayed on the HARVESTED CROPS to keep them from fungal harms.... one more reason to buy organic or grow your own, IMHO.

I prefer untreated seed when available, but I've purchased treated seed a few times when that was the only way a variety I wanted was available. The quantities of pesticide on the seed are miniscule and unlikely to be a problem to human or environmental health in a home garden, as long as you wash your hands after handling. I'm more concerned about worker exposure and emissions from the production of the pesticide and the treated seed.

I haven't noticed a trend toward more treated seed these days; I've just noticed it's mainly available from the companies that cater to market gardeners and farmers rather than mainly to home gardeners. So, how much of it I see depends on where I shop.

Is it possible Harris hasn't restocked some of their products yet for 2022? Maybe the untreated seed you're looking for will be available in a few weeks. Like you, I'm a big fan of Harris. Very fast shipping, excellent germination, and some really great varieties, plus they sometimes have amazing sales on things they're closing out. I got some lettuce seed this year for something like $.35 per pack, and various other things for less than $1. Regular prices seem pretty high on many things right now, though.
