How Much Does Surtivo® Cost?
Depending on the rate, about $5 to $7 per acre.
What Should I Expect after Application?
Generally, Surtivo® will provide upwards of 90% control dependent upon environmental and weather conditions. Larvae may continue feeding for 1-3 days after becoming infected with NPV and will typically die within 3-9 days. Smaller larvae die faster, and warmer temperatures will increase the speed of kill. Expect slower results when temperatures are cooler (less than 65°F). NPV-infected larvae will not show obvious symptoms of disease until 1-2 days before death.
Is Surtivo® Compatible with Other Insecticides?
When mixed with water, Surtivo® is highly compatible with the majority of insecticides and fertilizers. Ensure that the mixture has a pH of 8 or less before adding Surtivo® as alkalinity will damage the virus.
How Should Surtivo® be Stored?
Ideally, Surtivo® should be stored at temperatures below 34°F, however, it can be stored at room temperature (77°F or less) for up to 6 months and should never be kept in an environment above 86°F. Do NOT leave in direct sunlight for longer than 2 hours or in spray tank for extended periods of time. Unused product can be stored in the original container for future use.
Does Surtivo® Have Any Residual Activity?
The virus in Surtivo® is degraded by ultraviolet light. As a result, the sprayed virus may only be viable for a few days in the crop. However, once the initial population dies, huge quantities of virus will be released. This replicated virus will last for many weeks and will control recurring populations. Applying the virus while larvae are most active (feeding) increases the likelihood of ingesting and ultimately higher levels of control.
How Do I Know if I Have Corn Earworm, Soy Podworm, Soybean Looper and Tobacco Budworms in my Crop?
Corn Earworms are cream-colored but larger ones have variable coloration (pale green to rose to brown) and pale lateral stripes.
Soy Podworms have a tan head and alternating dark and light stripes running lengthwise down the body, and they have numerous tubercles (dark spots) with long spines.
Soybean Loopers are light to dark green with distinctive white stripes running down their sides. They are typically about one and one-fourth inches long. The soybean looper can be distinguished from green cloverworms by the fact that they have only two sets of prolegs on their abdomen compared to three sets for cloverworms.
Tobacco Budworms are a yellowish green with a yellowish head capsule. Later instars are greenish with dorsal and lateral whitish bands, and with a brown head capsule. Body color can be variable, and pale green, pinkish, dark reddish or maroon forms are sometimes found.
What is Surtivo®?
A biological insecticide that controls Chrysodeixis includens, H. armigera, H. zea, Chloridea virescens, Heliothis virescens(Corn Earworm, Soybean Podworm, Soybean Looper and Tobacco Budworm).
What is the Active Ingredient in Surtivo®?
A Mixture of Natural occurring viruses: Helicoverpa armigera Nucleopolyhedrovirus (HearNPV) andChrysodeixis includens Nucleopolyhedrovirus (ChinNPV)
How Does Surtivo® Work?
Surtivo® is a suspension of virus particles called Occlusion Bodies (OB’s). When larvae ingest OB’s by eating Surtivo® sprayed crops, they become infected with the virus. Using the insect’s own metabolism, the virus replicates itself and invades almost every cell of the insect – causing them to rupture. This releases a virus-laden liquid, which spreads throughout the crop, providing ongoing control of susceptible caterpillars.
What Pests Does Surtivo® Control?
Corn Earworm, Soybean Podworm, Soybean Looper and Tobacco Budworm
Does Surtivo® Work on Larvae Populations that have Developed Resistance to Synthetic Insecticides?
Yes. It is a valuable rotational mixing partner in controlling larvae resistant to synthetic insecticides. There are no known cases of resistance developing to NPV-based insecticides anywhere in the world.
Is Surtivo® Harmful to Beneficials?
No, Surtivo® is a species-specific biological insecticide used to control Corn Earworm, Soy Podworm, Soybean Looper and Tobacco Budworms with no impact on beneficial species. Actually, beneficial species help transmit the virus throughout the ecosystem more quickly, which can result in better coverage and control.
What are the Approved Crops for Surtivo®?

What is Surtivo®’s PHI or REI?
Surtivo® does not have a pre-harvest interval (PHI).The re-entry interval (REI) is 4 hours.
