Protecting Crops with «Meteor W.P.»: A Field Perspective

Dealing with anthracnose and downy mildew requires a reliable partner, and «Meteor W.P.» (based on copper hydroxide) is a go-to solution for many growers. Its contact action provides a robust barrier on the plant surface, preventing pathogens from colonizing the tissues. In my experience, the key to success with this wettable powder is proper suspension preparation to ensure consistent coverage without nozzle clogging.

Application and Dosage Tips

When preparing the spray tank, I always mix the powder into a slurry first before adding it to the main volume of water. The recommended rate of 0.3–0.5 kg/ha is generally sufficient to form a protective layer, though I adjust based on the density of the crop canopy and current infection pressure. The product is particularly effective for managing bacteriosis in tomatoes, acting as a direct suppressor of bacterial activity.

Key Operational Notes

• Treatment Frequency: You can apply the fungicide up to 3–4 times per season, which covers the most critical stages of vegetative growth.
• Safety and Pre-Harvest Interval: The product is rated under Hazard Class 3, requiring standard PPE. Always keep a 30-day pre-harvest interval to ensure safety standards.
• No Resistance Issues: Because copper hydroxide affects pathogens through non-specific pathways, there is a low risk of fungi developing resistance, making it perfect for your anti-resistance management program.

For any grower looking for a stable, predictable, and cost-effective contact fungicide, this product from Shanghai Sunrise Chemicals is a staple in the maintenance schedule. When applied correctly, it doesn't just treat the symptoms; it actively prevents spread across the plot.
