Replacement for Ortho Volck
For years I have successfully used Ortho Volck to control aphids on my euonymus bushes. I spray in late February. Volck is no longer available. I am looking for a replacement that is sake for birds but will protect the bushes. Can you suggest something?

Ortho Volck was just one particular product. There are several other horticultural oils on the market that are widely available. 'Sun Spray' is one.
