Virosoft CP4 is a codling moth granulovirus produced by BioTepp, Inc. that provides a natural alternative to chemical insecticides. It works by infecting and killing codling moth larvae when they ingest virus-coated eggs. Clinical studies show Virosoft CP4 significantly reduces codling moth populations with multiple applications at 7-14 day intervals and can be integrated into IPM and organic orchard programs. It has a stable formulation that stores well for many months under different temperatures.

Apply 2-3.2 oz/acre every 7-14 days
If Codling Moth pressure is high use 7 day interval
Begin sprays at egg hatch (2 weeks after petal fall) and continue as
needed but apply at least 2 sprays per CM generation
Apply in enough water for thorough coverage of the tree bark, foliage
and fruit
May be applied to Apple, Pear, Plum & Walnut trees
