Mode of action
Pyriproxyfen is a contact enteric insecticide. Its mode of action is associated with irreversible disruption of hormonal balance in pests. It affects numerous physiological processes in insects, similar to juvenile hormones, and acts as a potent inhibitor of embryogenesis, metamorphosis and adult insect formation.
When applied to eggs and larvae, pyriproxyfen disrupts preimaginal development, resulting in deformed unviable species with signs of a larva or imago.
Adult insects exposed to pyriproxyfen become sterile and unable to lay viable eggs, preventing the potentially harmful development phase.
Pyriproxyfen has long-term residual activity. A single treatment causes lethal changes in each stage of development, reducing both the treated and subsequent pest populations.
The innovative oil formulation improves the lipophilic properties of the product and extends the activity of the active substance. Oil enhances the contact properties of the product, ensuring even distribution and good adhesion of the insecticide to the insect’s body and treated surface. This ensures a rapid toxic effect on the insect and long-term protection during subsequent feeding on the leaves. Furthermore, the oil film on the treated surface keeps the active substance in liquid form for a longer period of time, preventing crystallisation, evaporation and washout by precipitation. As a result, the product remains effective even in adverse weather conditions.
Protective effect period
The product provides long residual activity throughout the growing
season. The product causes irreversible disruption of the hormonal
balance in pests, leading to abnormal development and eventual death.
Rate of exposure
As a long-acting insect growth regulator, the product causes pest
mortality both during application and at subsequent developmental
stages.
