A naturally occurring virus that infects and kills codling moth larvae, while preserving beneficial species.
Better Control at Lower Rates and Tank Mix Compatible
The active ingredient is naturally microencapsulated within protein occlusion bodies (OB). OBs must be ingested by a codling moth larva to be effective. The highly alkaline environment of the larval digestive tract dissolves the OBs, releasing the virus to infect the cells lining the larval gut to kill the pest.

Comments Apply in sufficient water to thoroughly wet the tree canopy without exces- sive runoff. Select a spray volume appropriate to tree size and density of foliage. For small trees use 50-100 gallons of spray per acre. Larger trees with denser canopy may require 100-200 gallons per acre. Consult your local Cooperative Extension Service if you need advice about how to attain good spray coverage in your orchard. Make at least two (2) applications of CYD-X® HP per codling moth larval gen- eration. Target small larvae early in their life cycle. Repeat as necessary to maintain control. CYD-X® HP breaks down under direct exposure to sunlight. If codling moth are still flying and laying eggs, reapply after 7-8 sunny days. If using temperature models (heat unit accumulation measured in degree days) and pheromone trap catch to predict codling moth development, make the first spray against the first larval generation around 250 degree days after codling moth Biofix (first moth flight). If targeting the second generation, start at approximately 1100-1200 degree days after biofix. “No Biofix” models (using heat units only, with no trap catch information) are now used in some growing regions. Consult your local Cooperative Extension Service for infor- mation about using degree day models to guide spray timing If not using heat units to time sprays, apply CYD-X® HP in the 1st and 2nd cover sprays against first generation larvae. For second generation, apply in the 4th and 5th cover sprays. Frequent applications at low rates may be more effective than one or two applications at high rate. |
