Certis offers Deliver™ – The Most Potent Bt Pound-for-Pound For Use in Orchards and on Vines

Certis USA introduces Deliver™, a new Bt bioinsecticide that is up to 5 times as potent—pound for pound—as conventional Bt products. The active ingredient of Deliver is a new strain of Bacillus thuringiensis (Bt) selected for its especially high concentration of Cry1Ac insecticidal protein. This makes Deliver particularly potent against Lepidopteran (caterpillar) pests, such as peach twig borer, navel orangeworm, Oriental fruit moth, omniverous leafroller and Western grapeleaf skeletonizer, that attack tree fruit, nut and vine crops. In comparison with traditional Bts, one container of Deliver treats more acres, resulting in lower use rates and lower cost.

For all biological insecticides, including Deliver, good coverage of leaf tissue is critical for effective pest control, because pests must ingest the Bt. To help growers achieve maximum coverage, Certis offers Deliver in a unique wettable granular formulation that provides uniform dispersion of the active ingredient in the spray droplets and promotes better spreading and sticking. For best results, Deliver should be used in concert with a good scouting program. Applications should begin when larvae are small.
