CYD-X infects and kills the larvae of codling moths. Each virus particle (also known as codling moth granulosis virus) is naturally micro-encapsulated within a protein occlusion body (OB) that protects it to some degree from degradation. Lab studies have determined that a dose of 1 to 2 OB's is all that is required to cause a lethal infection in half of the codling moth larvae tested. A single ounce of CYD-X biological insecticide contains nearly one trillion OB's. that kills the host.

  • Cyd-X must be mixed with water and applied as a spray to fruit and foliage.
  • Use non-chlorinated water at a pH near 7.0 in the spray-tank mix. Mix 1 tsp of Cyd-X per 5 gallons of water and apply directly to each tree using a hand pump sprayer or other suitable spray equipment. Spray just enough to wet all leaves and fruit with minimal run-off or dripping. Total coverage depends on the size of trees to be sprayed and the type of sprayer used.
  • Apply Cyd-X first in late spring or early summer, when eggs of the first generation of codling moth begin to hatch. For maximum effectiveness, apply Cyd-X at least twice during each larval generation. When pest pressure persists, additional applications may be necessary in mid- to late summer. Consult your local Cooperative Extension Service for more information about the best timing of codling moth sprays.
  • Use with Codling Moth Trap Kit for monitoring of adult male codling moths

See product use instructions for complete information.

For best results, CYD-X should be refrigerated when not in use and should last at least a year. Non refrigerated product should be used within 3 months. Bioactivity of the virus can be degraded by exposure to high temperatures ( > 90°F) for long periods. Always store CYD-X in its original bottle in a cool, dry place, out of direct sunlight. Shake well before use. CYD-X can also be frozen for extended storage without harm.
