Dynamec is active against all stages where the pest feeds; it prevents or stops the formation of galleries by the larvae of leafminers. A marked reduction in fertility and spawning was observed in females coming into contact with the product.

Abamectin works by preventing the transmission of nerve impulses from nerves to muscles. The pests are quickly paralyzed, stop feeding and die after 3 to 4 days.

Dynamec activity increases with temperature.
