Grub,

I do a Daconil/pyrethrin mix too (to control spider/russet mites, and early blight of course). The product I use is PyGanic (a 5% pyrethrin/95% inert solution) and I mix at the lowest recommended rate of 1.5 teaspoons per gallon.

I don't have any days in summer that are below 25C (~77F) either. And not many evenings or mornings, unless I were to get up at 3:00 am to spray, and I'm just not going to do that.

But I think it's important to try and only use pyrethrins and/or the Daconil/pyrethrin mix when the sun is off the plants *and* it's below 85F (~30C) or so. That generally works well for me without burning the plants -- just my experience.

Also, what's the percentage concentration of your mix and at what ratio are you mixing it with water -- maybe you could use just a bit less and still get good results?
