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.
The label recommended application rate for CYD-X is 1 to 6 fl. oz. (30 to 180 ml) per acre. This equates to 1 to 6 trillion OBs per acre. In most cases, apply 3 fl. oz. CYD-X per acre in sufficient water to obtain thorough coverage of the orchard canopy without excessive runoff, which could carry the virus off the tree. At 100 gallons of spray per acre, this is equivalent to 1 to 1½ teaspoons of CYD-X per 5 gallons of water. Actual application volume will depend on the type of spray equipment used, but concentrated sprays are usually more effective for applying CYD-X than are dilute sprays. CYD-X can be applied at lower label rates (1 or 2 fl. oz. per acre) if codling moth pressure is low or frequent applications are planned. Use non-chlorinated water at a pH near 7.0 in the spray-tank mix.
Always plan to apply CYD-X at least twice during each larval generation targeted. Multiple sprays at low rates (1 to 3 oz.) and short intervals are likely to provide better control than a single spray at a high rate (4 to 6 oz.) One economical strategy is to use a high rate (4 to 6 oz.) for the initial spray to initiate a virus outbreak in the larval population, with subsequent sprays at reduced rates (1 to 3 oz.) to maintain the level of infection.

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.
