Summary

In the control of codling moth it is common to combine the granulovirus with other agents,
especially fungicides, in spray application. Therefore the knowledge about the influence of
these agents on the efficacy of the virus in tank mix is very important. Studies on this
subject were part of a project supported by BMELV (German Federal Ministry for Food,
Agriculture and Consumer protection) at the Institute for Biological Control of JKI in
Darmstadt.
The granulovirus of Cydia pomonella (L.) (CpGV) was mixed with 10 different agents at
concentrations as applied in the field. After the exposure the virus activity was calculated
from larval mortality determined in bioassays with neonates of a susceptible codling moth
strain.
Only two agents with a pH of 11 (sodium silicate (water glass) and calcium polysulfide
(lime sulphur)) reduced the virulence of CpGV significantly.
