Yes, you can use Makhro Agro Orius 250 EW on houseplants, as it is registered for use on indoor and outdoor ornamentals. However, because it contains Tebuconazole (a strong, chemical systemic fungicide), you must follow strict safety precautions when applying it indoors.

How to Apply It Safely

• Spray outdoors: Take your houseplants to a well-ventilated outdoor area, patio, or balcony before spraying to avoid inhaling the chemical mist.
• Let it dry: Allow the foliage to dry completely before bringing the plants back inside your living space.
• Wear protection: Use gloves and avoid getting the spray in your eyes or on your skin.
• Protect pets: Keep pets and children away from the plants until the chemical has fully dried.

Target Diseases

Makhro Orius 250 EW acts systemically, meaning it absorbs into the plant's tissue to fight infections from the inside out. It is highly effective against:

• Powdery Mildew
• Black Spot
• Rust

Dosage and Mixing Instructions

If you have the concentrate liquid version, follow the mixing instructions provided on the official Makhro Orius Label:

• The Mix: Mix 1 mℓ of Orius 250 EW per 1 ℓ of water (or 5 mℓ per 5 ℓ of water).
• Application: Pour the mixture into a hand spray bottle, shake well, and spray a fine mist evenly over all leaf surfaces.
• Timing: Spray early in the morning or late afternoon to avoid leaf scorch from direct sun. Repeat every 7 to 10 days if the fungal infection persists.
