Can I use Criterion 75 WSP for kermes scale?


While the Criterion 75 WSP is not labeled specifically for kermes scale, it is labeled for soft scale species in general and should yield good results especially if caught in the early life stages of the scale. For trees, use 1 packet per 24-48 inches of trunk diameter in no less than 10 gallons of water per 1000 sq/ft and apply uniformly as a drench around the base of the tree and directed into the root zone.
