The product

Powerful new mode of action that works

Calantha is a new foliar insecticide that provides effective control of the Colorado potato beetle (CPB) in potato crops. Calantha is powered by ledprona, a new class of bio-insecticide offering a novel Mode of Action (MoA) that provides a new tool for resistance-management with no detectable residues on potatoes.

About Calantha

The benefits

An effective and novel bio-insecticide  

Calantha’s effectiveness has been confirmed through more than 250 field trials over five years across the USA, Canada and Europe. It consistently controls CPB while meeting industry standards for yield and defoliation protection. These trials were performed in small and large plots involving extension researchers and prominent industry growers in key potato production states.

What people say

How it works

Calantha in action


Mixed with water and sprayed over potatoes using standard agricultural practices, Calantha™ is used at a rate of a few grams per acre. This is significantly lower than most currently used insecticides against CPB.

Mode of Action

Consumption of Calantha™ causes CPB to stop feeding within 3 days. Affected larvae will darken and become inactive before dying. Effectively protecting the potato plants from defoliation and preserving tuber yield.

Environmental Impact

Field studies show that Calantha™ has little to no impact on non-target organisms tested, leaving beneficials - including honeybees, butterflies, earthworms, ladybugs and other beneficial insects - unaffected. In the soil, water and on leaf surface, the active ingredient itself degrades within days.
