Insecticidal Virus for Use in Greenhouses and Open Fields for the Control of the Corn earworm, the Tobacco budworm and the Old World bollworm 

PRODUCT INFORMATION
SHAKE WELL BEFORE USING
HELICOVEX acts very specifically against larvae of Helicoverpa sp., such as the corn earworm, Helicoverpa zea (also known as cotton bollworm, tomato fruitworm), the tobacco budworm (Helicoverpa/Heliothis virescens) and the Old World bollworm (Helicoverpa armigera). After ingestion by the larva, the virus multiplies within the cells of the host insect causing a fatal infection. Rapid virus multiplication within the host cells results in cell destruction and death of the organism, typically within 3 – 7 days.

Application
Start spraying before larvae hatch from the eggs and onto young instar larvae after hatching. If moths are still flying and laying eggs, re-apply as directed in the table below. Due to certain weather conditions, such as lower temperatures, the flight, egg laying, and hatching may extend over a longer period of time making more applications necessary. Frequent applications at low rates may be more effective than one or two applications at high rates.
Use sufficient water to obtain thorough, uniform coverage. Because HELICOVEX acts through ingestion of treated plant material, thorough spray coverage is essential for optimum control of targeted pest insects. Using increased water volumes will typically result in better spray coverage, especially under adverse conditions such as dry hot weather or dense plant foliage. Run-off should be avoided. Helicovex is rainfast as soon as it has dried.
For greenhouse applications: the re-application interval can be extended to 7 – 14 days, because of reduced UV-radiation. However, at fast plant growth make sure to cover young tissue with intervals of 6 – 8 days.
For chemigation applications: see “CHEMIGATION” section of this label for guidance.
