I do have daconil which I bought several years ago when I was visiting home. You can't get it here in Quebec anymore. Does it have a shelf life? It's been in my garage which we do heat in winter. I have just been reluctant to use it.
Bill, serenade has worked for me - however, I confess that I have not been that diligent with it. I have had good results with copper. Sulfur is another one I have stayed away from.
Ray, thanks for the article. So far only one plant, NAR is showing some disease but nothing serious and whatever it is has stayed only on NAR. I have sprayed the other plants with Serenade and will spray again with copper if necessary.

I used sulfur in the past to control spider mites and it worked great but there was one big problem. Down here it is a rare thing to have spider mites when the temperatures are not over 90 and sulfur will definitely damage the foliage if it is used when it is too hot.

Sharron I'm surprised you can't get Daconil because it is so widely available down here. Why don't you spray the NAR plant having the disease issues with copper and then the next day spray it with the old Daconil you have. I have no idea what kind of disease you are dealing with on the plant. If you think it might be LB then you will need to spray all your plants with the diluted bleach spray and probably remove the NAR plant and hope you aren't too late.

I used long ago sulfur against powdery mildew. It didn't really work but I swore I would never use the stuff again. The smells just stays for a long time. You get any on the tomatoes, you can forget about eating. No matter how much I washed them it still had a bit of taste.

Sharon, is all chlorothalonil unavailable, or just the brand name Daconil? It can also go under the name of Ortho Max and Bravo down here. IIRC, it sometimes goes by Echo in Canada.

I took me a while to get the 10% Perm and DE. To hold me over I sprayed with Spinosad last weekend. Yesterday evening I sprayed with DE-Permethrin mix.
The dawn really helped it stick as all plants looked to be covered in a white frost.

Sunday evening I am going to add Copper to the mix and reapply it again. I have destroyed several plants beyond help. I also sprayed a few cucumber plants that were infected. The bugs are definitely assassin long pipes (see pic) but unfortunately the mites were winning the war so all in the path may be casualties.

Bill when do these pests stop reproducing? October?

Daconil is also marketed as Broad Spectrum Fungicide

I had one season of Assassin bugs galore and had a virtual pest free season that year and never had to spray but haven't seen more than an occasional one since then. I have no idea why I had so many of them that year but I would see hundreds of them some days. Now the only bug that looks similar that shows up in numbers are leaf footed bugs and stink bugs. I did have a couple of assassin bugs on my squash this year but that was all I have seen.

As to mites stopping in October it all depends on the heat and whether it stays hot and dry. Last year I was still having mites show up in October but not as bad as earlier but last year was extremely hot and dry right up until mid November here.
You should see a real decline in mite activity if the DE doesn't get rained off the plants.

I lost several plants last year because I allowed them to get too bad on the plants before spraying but most survived and thrived until they froze. Some of them looked pretty bad after I clipped all the badly damaged foliage off of them but with a big dose of TTF and good watering they recovered well.

I found a half dozen plants with mites a few days ago and sprayed everything with Permethrin, DE, Dawn and Copper. My plants are nice and hazy looking now but the mites seem to be stopped for now despite the 100 degree heat. I had to go out and water them all yesterday and there is a 50% chance of rain for the next few days.
I also give my plants a good feeding of TTF and pruned them just before watering and fertilizing.

Good luck.

Bill
