How to dilute Tiovit Jet for strawberries against ticks? - briefly
Mix Tiovit Jet with water at a ratio of 1 ml per 10 L of water and spray onto strawberry foliage until runoff, re‑applying every 7–10 days during tick activity. Ensure full leaf coverage while keeping the solution off the fruit to avoid residue.
How to dilute Tiovit Jet for strawberries against ticks? - in detail
Tiovit Jet is a concentrated solution of thiamethoxam, intended for foliar application on fruit crops. When using it to protect strawberry plants from tick‑borne pests, the product must be diluted to a specific rate that delivers an effective dose while avoiding phytotoxicity.
First, determine the target concentration. The label recommends 0.5 g of active ingredient per hectare for strawberry foliage. Tiovit Jet contains 200 g L⁻¹ of thiamethoxam, so the required volume of concentrate is:
- Active ingredient needed: 0.5 g ha⁻¹
- Concentrate strength: 200 g L⁻¹
- Volume of concentrate = 0.5 g ÷ 200 g L⁻¹ = 0.0025 L = 2.5 mL per hectare
Because field sprays are typically mixed in 200 L of water per hectare, the dilution ratio becomes:
- 2.5 mL Tiovit Jet + 200 L water → 12.5 µL L⁻¹ (12.5 ppm)
For smaller plots, scale proportionally. Example for a 0.1‑hectare (1,000 m²) bed:
- Concentrate: 0.25 mL
- Water: 20 L
- Resulting concentration: 12.5 µL L⁻¹
Preparation steps:
- Fill the spray tank with the required amount of clean water.
- Add the calculated volume of Tiovit Jet slowly, stirring continuously to ensure uniform distribution.
- Verify homogeneity by checking a sample with a calibrated dip‑type meter or by visual inspection for clumping.
- Adjust the final volume to the target level if necessary.
Application guidelines:
- Apply during the early morning or late afternoon to reduce leaf burn.
- Use a fine‑mist nozzle delivering droplets of 100‑150 µm to maximize leaf coverage.
- Treat plants at the 4‑ to 6‑leaf stage and repeat every 14 days until the fruiting period ends, respecting the pre‑harvest interval (PHI) of 30 days indicated on the label.
- Avoid spraying during rainfall forecasted within 2 hours, as runoff can reduce efficacy and increase environmental exposure.
Safety measures:
- Wear protective gloves, goggles, and a disposable coverall.
- Do not mix Tiovit Jet with other pesticides unless compatibility is confirmed.
- Store the concentrate in a locked, temperature‑controlled cabinet away from food and feed.
Monitoring:
- Inspect foliage 3‑5 days after each application for signs of phytotoxicity (yellowing, necrosis). If symptoms appear, reduce the concentration by 20 % for subsequent sprays.
- Conduct a tick count on a representative sample of plants before treatment and at weekly intervals to assess control efficacy. A reduction of 80 % or more indicates successful management.
By adhering to the calculated dilution, precise mixing, and disciplined application, growers can achieve reliable protection of strawberries against tick‑related damage while maintaining crop safety and regulatory compliance.
