Key Usage Guidelines / Best Practices

• Use when pest infestation reaches action threshold level (ATL) — do not spray unnecessarily. 

• Spray thoroughly, coating both upper and lower leaf surfaces for good control.

• Spray interval: repeat every 7 days if needed (for many vegetable crops) but only when necessary. 

• Limit number of sprays per crop / season depending on crop:
    – Rice: max 2 sprays / season 
    – Long bean & mustard: 3 sprays / season 
    – Tomato: 4-6 sprays / season 
    – Eggplant, okra: up to 6 sprays / season 
    – Tea: 6-8 sprays / year 
    – Chili: up to 10 sprays / season 

• Rotate with other insecticides from different action groups to manage resistance.
