Pre-Harvest Interval (PHI):
- No specific PHI reported for this product.
Application Management:
- Fipronil is effective against a wide spectrum of major and destructive insect pests, exhibiting a rapid knockdown effect that causes immediate paralysis and death.
- Its moderate systemic action allows its use both for seed treatment and soil application.
- It is particularly effective against insect populations resistant to organophosphates, carbamates, pyrethroids, and cyclodienes.
- Provides long-lasting residual control when sprayed on foliage.
- Can be used both in nurseries and in main fields.
- In soil, fipronil degrades quickly into non-toxic byproducts, reducing the risk of water contamination and contributing to environmental safety.
- Due to its low required dosage and reduced number of applications, it minimizes overall pesticide load.
