Mechanism of action

"Herold® has a contact and intestinal action, disrupts molting processes of pests.

It inhibits chitin synthesis and prevents formation of cuticle when molting. Germicide has no effect on imago, but disrupts development of eggs and larvae (ovicide and larvicide action).

Larvae die at the next molting, when the cuticle is torn, and the contents of the body flows out. The maximum mortality of the pests is observed in 2 weeks after treatment. Avicenny the effect observed with the females laying eggs on treated plants. Ovicide effect is visible when female insects laying eggs on treated plants."
