Product Description
MAVRIK 2 F – From the Champion’s Record
Tau-fluvalinate is a unique synthetic pyrethroid that acts differently on the nervous system of pests compared to other pyrethroids.
- Superior photostability and thermostability.
- Water-insoluble – highly resistant to rain wash-off.
- High lipid solubility – penetrates insect cuticle quickly.
- Specific spectrum targeting sucking insects (aphids, bugs), some beetles, and lepidopterans.
- Can be applied at higher temperatures without reduced efficacy.
- Tolerant to beneficial insects and pollinators.
- Long residual activity with visible knockdown effect.

Recommendations for Use
Wheat: Apply when economic threshold is reached. Autumn treatment protects young plants; late treatments protect spikes from aphids.
Rapeseed: Can be applied even during flowering without affecting bees. Long persistence ensures protection until harvest.
Apple: Apply during or immediately after flowering. Treatment can be repeated in summer. Use 1000 L/ha for complete tree coverage.
Mode of Action
MAVRIK 2 F contains Tau-fluvalinate derived from the amino acid valine in milk casein. Unlike other pyrethroids, Tau-fluvalinate keeps sodium channels open at nerve endings, disrupting membrane depolarization. This causes metabolic disturbances, disordered hyperactivity, and pest death. The product is photostable, thermostable, rain-resistant, safe for beneficial insects, and acts via contact and ingestion with long residual and visible knockdown effect.
