MBI’s dry formulation of bio-insecticide Grandevo registered in Florida

Marrone Bio Innovations has announced that a new dry formulation of Grandevo has been registered by the Florida Department of Environmental Protection. This registration follows EPA approval of the formulation on May 1, 2012.

"Grandevo is breaking new ground in controlling Asian citrus psyllid. Its biological efficacy and operational flexibility is a very welcome addition for Florida growers who now have a new tool in the battle to slow the spread of citrus greening," said Maris Klavins, product manager for Marrone. “The introduction of Grandevo signals the availability of the first new broad-spectrum microbial insecticide in nearly 50 years and offers growers the ability to employ bioinsecticides in ways never before thought possible.”

Grandevo is a new, broad-spectrum bioinsecticide/miticide that has proven to be highly effective against Asian citrus psyllid (ACP). In commercial applications and trials, Grandevo showed activity against psyllid nymphs as well as adults. Grandevo controls psyllid populations by reducing egg laying and repels adults by its irritant properties in treated trees. 

Naturally derived, Grandevo features complex modes of action that are highly active against labeled chewing and sucking insects and mites, with limited disruption of beneficial insects. Control of pests is achieved by unique combinations of repellency, oral toxicity, reduced egg hatch, and reduced fecundity (ability of a pest to reproduce).

Grandevo is approved for use on ornamental plants and edible crops in fields and greenhouses and it can be applied by air, ground, or chemigation.
