Active Substance:
Mode of Action:
Shirudo acts by contact and ingestion on phytophagous mites, including summer eggs, larvae, nymphs, and adults. Tebufenpyrad inhibits mitochondrial respiration in mite cells by disrupting the electron transport chain, leading to rapid death. The product has translaminar action, allowing control of mites on both sides of leaves and maintaining its efficacy even under heavy rainfall conditions.
Usage and Recommended Dosage:
- Target Crops: Apple, pear, strawberry, hops, vegetables (cucumbers, zucchinis, melons, watermelons, tomatoes, eggplants, peppers) in protected areas, and ornamentals (roses) in protected areas.
- Controlled Pests: Tetranychid mites, including Tetranychus urticae and the red fruit tree spider mite (Panonychus ulmi).
Recommended Dosage:
- Apple and pear: 0.5 kg/ha, applied 7 days before harvest.
- Strawberries: 0.75 kg/ha, applied 3 days before harvest.

- Vegetables in protected areas: 0.8-1 kg/ha, applied 3 days before harvest.
- Ornamentals (roses) in protected areas: 0.5 kg/ha, no waiting period.
Recommendations:
- Apply the treatment at the first appearance of mites, ensuring uniform coverage of the crop.
