The product “works by affecting the potassium channels in the pests’ nervous systems, permanently and irreversibly putting a stop to feeding within 30 minutes of application,” the insecticide’s overview says. “It provides residual control and helps protect both sides of the leaf from yield-robbing pests due to its translaminar activity.”
Translaminar means the insecticide penetrates the leaf tissues and forms a reservoir of the active ingredient within the leaf.
Farmers may only use Carbine for a limited time.
