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.
