FAQ

1 Q: What is the main use and advantage of this copper fungicide?

A: Copper Hydroxide 77% WP is a broad-spectrum, contact-type protective fungicide and bactericide. Its core advantage lies in the 77% high active ingredient content, which delivers strong and rapid disease suppression. With a multi-site mode of action, it effectively delays resistance development in pathogens and forms a durable protective film on plant surfaces to block fungal and bacterial infections.

2 Q: Which crops and diseases is it most effective against in our regions?

A: It performs exceptionally well on key local crops including vegetables (tomato, cucumber, pepper, lettuce), fruits (apple, citrus, grape, mango), cereals (rice, wheat), and ornamental plants. It provides reliable control of major diseases such as downy mildew, bacterial blight, anthracnose, black spot, damping-off, and fungal leaf spots that are prevalent in your market.

3 Q: Why is the WP (Wettable Powder) formulation beneficial?

A: The WP formulation offers practical advantages for agricultural use: it has excellent water solubility and suspension stability, ensuring uniform mixing in spray tanks. It adheres firmly to plant surfaces even in light rain, providing long-lasting efficacy. Additionally, it is easy to store, transport, and measure, making it cost-effective and suitable for both small-scale farming and large-scale commercial cultivation.

4 Q: How should it be applied for best results in our climate?

A: For optimal performance, apply as a preventative treatment 7-10 days before expected disease onset or at the first sign of infection. Ensure thorough coverage of leaves, stems, and fruits—pay special attention to undersides of leaves. Reapply every 7-14 days, adjusting intervals based on rainfall intensity and disease pressure. Avoid spraying during midday high temperatures (above 32℃) or when plants are water-stressed to prevent phytotoxicity.
