Bioinsecticide Available in California

Marrone Bio Innovations (MBI), has received approval from the California Department of Pesticide Regulation for a new formulation of one of its biological insecticides, Grandevo WDG. Grandevo WDG is a water-dispersible granule that offers improved handling and mixing properties, as well as more convenient packaging.


A broad-spectrum bioinsecticide, Grandevo WDG controls a variety of insects on a wide range of crops, including navel orangeworm (NOW) in almonds, Asian citrus psyllid in citrus, lygus bug in strawberries, thrips in vegetables, berries and leafy greens and spotted wing drosophila in berries, whiteflies in cucurbits, and mealybug in grapes.

Grandevo WDG insecticide/miticide is derived from non-living bacteria that effectively controls a wide variety of chewing and sucking insects and mites from the unique action of multiple compounds through repellency, ingestion, and reduction of pest fertility. In an integrated pest management (IPM) program, Grandevo WDG offers multiple modes of action that can significantly benefit producers trying to reduce the risk of insect resistance. Grandevo WDG is exempt from the requirement of tolerances and therefore can be sprayed right up to harvest without creating concerns for exported produce or produce that must meet strict residue requirements of the food marketing chain.

“We expect this new formulation of Grandevo WDG to create new uses, address additional market segments for both pests and crops, and provide an easier, more effective and efficient experience for our customers,” says Pam Marrone, Ph.D., CEO and founder of MBI.

Grandevo WDG offers improved handling and convenient packaging. The water-dispersible granule mixes easily in spray tanks. Grandevo WDG comes in a 6- or 20-pound bag, which has an easy tear-top that allow mixers convenient access.

“Grandevo is an excellent rotational partner with other insecticide/miticides, including MBI’s own Venerate bioinsecticide/miticide. Use Grandevo WDG early in the pest’s population life cycle before they build up in numbers, to reduce reproduction and stop feeding, then follow with another product such as Venerate, which works through contact, via an insect growth regulation mode of action, that differs from the insecticidal mechanisms of Grandevo”, says Lisa Malabad, MBI’s insecticide/nematicide product manager.
