Pyridaben 20% WP

Pyridaben 20% WP is a contact-acting acaricide formulated to eliminate mites at all developmental stages—eggs, larvae, nymphs, and adults—with a focus on red spider mites and similar arachnid pests. Leveraging its rapid knockdown effect and long-lasting residual activity (up to 21 days), this low-toxic solution (WHO Class III) ensures reliable pest management in orchards and fruit farms, particularly for apple trees. Its stability across temperature variations (10–30°C) makes it suitable for spring-autumn applications, while ultra-fine particle technology enhances rainfastness and plant adhesion.

Ideal Crops: Apple orchards, stone fruit farms, berry plantations

2. Mode of Action

Mechanism: Disrupts mite nervous system via contact, causing rapid paralysis and mortality
Key Benefits:
- All-Life-Stage Control: Eliminates eggs and mobile stages in a single application
- Weather Resilience: Rainfast within 60 minutes post-application

Application Protocols for Optimal Results

Crop	Pest	Dosage	Application Timing	Method
Apple Trees	Red Spider Mites	45–60 ml/ha	7–10 days post-bloom (egg hatching/nymph phase)	Uniform foliar spray

Critical Tips:

Avoid spraying in winds >15 km/h to prevent drift
Reapply only if pest density exceeds threshold (≥5 mites/leaf)
Rotate with benzoylureas or metamizoles every 2–3 applications
