Conserve SC will need to be used within 24 hours of mixing.
Spinosad wil not persist in the environment. Sunlight and soil microbes break it down into carbon, hydrogen, oxygen and nitrogen. It is classified as an organic substance by the USDA National Organic Standards Board that is safe to be used on vegetables as labeled. Conserve SC itself is not OMRI or NOP approved. We also sell Natural Guard Spinosad Landscape and Garden RTS, which is certified organic.
Conserve SC can be applied as a mound drench to treat fire ants. Per the product label:
Dilute Conserce SC at a rate of 0.1 oz. per gallon of water.
"Apply diluted Conserve SC to individual fire ant mounds as a drench application. Use 1 to 2 gallons per mound depending upon the mound size. For mounds less than 8 inches in diameter, use 1 gallon of dilution per mound. Use a higher volume, up to 2 gallons, on mounds 8 inches or larger in diameter. Apply approximately 10% of the dilution volume around the perimeter of the mound out to about 12 inches and pour the remaining volume directly on the mound. Do not disturb mounds prior to application. If possible, apply following a recent rainfall. For best results, apply in cool weather, 65 to 85 degrees F, or in early morning or late evening hours. Treat new mounds as they appear. Do not use pressurized sprays as they may disturb the ants and cause migration, reducing control."
Conserve SC will start working by contact and ingestion within minutes of application, but more results will be evident within 1-3 days. Conserve SC will continue to work for up to 14 days after application.
Conserve SC could harm nematodes if they contact a wet surface so it would not be recommended to apply at the same time. Best to wait a few days in between applications.
A great product to use for gypsy moths and similar caterpillars would be a product containing natural Spinosad, such as Conserve SC. This should be applied during the spring caterpillar feeding stage with thorough coverage on all leaf surfaces. Conserve SC is great if you have a large area or number of trees to treat. If you are only treating a few trees, then you could use Monterey Garden Insect Spray.
Conserve SC is not labeled to control ticks so we cannot recommend it.
