How to cultivate sinosan for flea control? - briefly
Plant sinosan in well‑drained soil, sow seeds in early spring, keep rows 30 cm apart, and harvest leaves before flowering; the foliage’s glucosinolate content repels fleas when used as a dried powder or brewed tea. Apply the preparation to pet bedding or indoor areas for short‑term flea control.
How to cultivate sinosan for flea control? - in detail
Cultivating sinosan (Sinapis alba) as a biological agent against fleas requires precise agronomic practices. The plant’s glucosinolate content, especially sinigrin, releases volatile compounds that repel or kill flea larvae when the foliage is decomposed or applied as a dry mulch.
The following protocol outlines each stage from seed selection to field application.
-
Seed selection and treatment
• Choose certified, high‑viability sinosan seeds.
• Apply a fungicidal dressing (e.g., copper‑based) to reduce seed‑borne pathogens.
• Pre‑soak seeds for 12 hours in lukewarm water to accelerate germination. -
Soil preparation
• Opt for well‑drained loam with pH 6.0–7.5.
• Incorporate 2 % organic compost to improve moisture retention.
• Perform a deep tillage to a depth of 20 cm, followed by a fine harrow to create a smooth seedbed. -
Sowing
• Broadcast seeds at a rate of 30 kg ha⁻¹, then rake lightly to achieve a seed‑to‑soil contact of 1–2 cm.
• Water immediately after sowing to reach field capacity; maintain soil moisture at 60–70 % of available water capacity during emergence. -
Crop management
• Monitor for weed competition; apply selective pre‑emergent herbicide (e.g., clomazone) if necessary.
• Conduct a single nitrogen top‑dress (30 kg N ha⁻¹) at the 4‑leaf stage to sustain vegetative growth.
• Inspect for pests such as aphids; use neem‑based biopesticides if infestations exceed economic thresholds. -
Harvest and processing
• Harvest mature plants at the flowering stage (approximately 45 days after emergence).
• Cut foliage and stems, then air‑dry in a shaded, ventilated area for 48 hours to preserve glucosinolate integrity.
• Grind dried material to a coarse powder; store in airtight containers away from direct sunlight. -
Application for flea control
• Distribute the powder uniformly over pet bedding, kennels, or outdoor resting areas at a rate of 200 g m⁻².
• Alternatively, incorporate the dried mulch into compost heaps; the resulting leachate can be sprayed on infested zones.
• Reapply every 3 weeks during peak flea activity periods to maintain effective concentrations of repellent volatiles.
Adhering to these steps maximizes sinosan’s bioactive compound production, providing a sustainable, non‑chemical method for reducing flea populations in domestic and agricultural settings.
