ledprona (Calantha)

Calantha is a bio-insecticide for the selective control of Colorado Potato Beetle on potatoes. It works by ingestion, so good coverage is important. Larvae stop feeding within 2-3 days of application, but it may take 7-10 days for treated larvae to die. Apply via ground or air equipment using at least 10 or 5 gallons of water, respectively. Chemigate using less than 0.2 inches of water, and maintain agitation of the spray solution during the application. Apply to small larvae. Reapply in 7-10 days if needed. Two to 4 successive applications can be made to a single generation of the pest, but treat the next generation with an insecticide that has a different mode of action. Calantha is a Group 35 insecticide (RNA interference mediated target suppressor).
