The Environmental Protection Agency recently registered Madex HP insecticidal virus to control codling moth and Oriental fruit moth in pome and stone fruit.
The product contains the active ingredient, Cydia pomonella granulovirus isolate V22, according to the label.
The virus targets the larvae, or caterpillars, of both codling moth and Oriental fruit moth but is harmless to humans or other animals.
It has a zero-day pre-harvest interval.
The manufacturer is Andermatt Biocontrol AG of Grossdietwil, Switzerland, and it is marketed in the United States by Certis USA, Columbia, Md.
No resistance to the virus has been documented in the United States.
But European researchers have found several codling moth populations with low susceptibility to the Cydia pomonellavirus, according to research published in the March 2013 issue of Journal of Applied Entomology.
