How to poison spider mite on eggplants? - briefly
Treat eggplant foliage with a registered miticide such as «abamectin» or «spirotetramat», applying the label‑recommended dosage to fully wet leaves and fruit. Follow with re‑applications every 7–10 days until monitoring shows mite numbers below economic thresholds, respecting any pre‑harvest interval.
How to poison spider mite on eggplants? - in detail
Spider mites constitute a serious pest on eggplant foliage, causing stippling, bronzing, and reduced fruit set. Effective control relies on timely application of acaricidal agents that disrupt mite metabolism or respiration.
• Synthetic acaricides commonly used include: – Abamectin (0.5‑1 mL L⁻¹, repeat after 7 days if infestation persists) – Spiromesifen (0.2‑0.4 mL L⁻¹, interval of 14 days) – Bifenthrin (0.05‑0.1 mL L⁻¹, re‑treatment after 10 days) – Etoxazole (0.3‑0.5 mL L⁻¹, follow label‑specified pre‑harvest interval)
• Inorganic options: – Sulfur dusting (2‑3 kg ha⁻¹, apply early morning or late evening) – Neem oil emulsions (2‑3 % v/v, repeat every 5‑7 days)
Organic biocontrol products: – Spinosad (0.5‑1 mL L⁻¹, effective against all life stages) – Beauveria bassiana formulations (1 × 10⁹ cfu mL⁻¹, weekly applications)
Application guidelines:
- Inspect leaves when mite populations exceed 5 mites cm⁻².
- Apply the chosen product to both upper and lower leaf surfaces until runoff.
- Rotate chemicals with different modes of action to prevent resistance buildup.
- Observe pre‑harvest intervals and maximum residue limits for each product.
Safety considerations: – Wear protective gloves, goggles, and a respirator mask during handling. – Avoid spraying during flowering to protect pollinators. – Store acaricides in locked, ventilated areas away from foodstuffs. – Dispose of empty containers according to local hazardous waste regulations.
Integrating cultural practices—such as regular irrigation to reduce dust, removal of heavily infested leaves, and introduction of predatory mites—enhances chemical efficacy and sustains long‑term control of spider mite populations on eggplants.
