Julie, I got your PM, but will also respond here for anyone else who is interested. Bear in mind that the special label for erinose is slightly different than the regular label. The rate is 44 cups per 100 gallon for erinose mite. In 4 gallons that is almost exactly 1.75 cups. Follow the label for PPE (Personal Protective Equipment). Make sure to get full coverage on both sides of the leaf and on the trunk and branches as well. Apparently, the sulfur lasts longer on the rough bark surface and can still kill the mites if they come into contact with it. The spray interval on the erinose label is 10-14 days. Don't spray more than that.
