Insecticides
Hexaflumuron 10% EC (Consult)
Hexaflumuron is an ovicide and larvicide that acts primarily via ingestion and works gradually. It is most effective on immature stages such as early-instar larvae and nymphs.
Product Name: Hexaflumuron 10% EC (Consult)
Type: Systemic Insect Growth Regulator, Active by Ingestion
Group: Benzoylurea
Pre-Harvest Interval (PHI): 29 days (for pistachio)
Application Management:
- Hexaflumuron is an ovicide and larvicide that acts primarily via ingestion and works gradually. It is most effective on immature stages such as early-instar larvae and nymphs.
- It affects all life stages of various insect species. Its primary mode of action is inhibiting larval molting, causing death when insects fail to molt.
- Hexaflumuron also reduces adult mating and oviposition. Timely application is crucial to maximize its ovicidal effect, ideally at the appearance of the first eggs. Initial and timely spraying reduces crop damage significantly.
- Highly toxic to aquatic microorganisms and honeybees.
Compatibility and Mixing:
- Effective mainly against Lepidoptera, Coleoptera, Diptera, and some other larvae.
- Limited effect on sucking insects, except pistachio psylla, pear psylla, and whiteflies.
