How can I get rid of spider mites on eggplants? - briefly
Apply insecticidal soap or neem oil to affected foliage, thoroughly covering both sides of the leaves, and prune any heavily infested stems. Keep humidity low and inspect plants weekly to catch new infestations early.
How can I get rid of spider mites on eggplants? - in detail
Spider mites damage eggplant foliage by feeding on cell contents, causing stippling, yellowing, and leaf drop. Early detection and swift action prevent severe loss.
Inspect plants regularly, especially the undersides of leaves, for tiny moving dots or fine webbing. If infestation is confirmed, begin with cultural measures: prune heavily infested leaves, discard them away from the garden, and improve air circulation by spacing plants 2–3 feet apart. Water the soil deeply once a week to reduce plant stress; avoid overhead irrigation that creates a humid environment favorable to mites.
Apply mechanical control by washing foliage with a strong jet of water for 30 seconds, repeating every 3–4 days until populations decline. For persistent colonies, use a fine‑toothed brush or cotton swab dipped in soapy water to remove mites manually.
Biological options include releasing predatory insects such as Phytoseiulus persimilis, Neoseiulus californicus, or Amblyseius swirskii. Distribute the predators according to the label, typically 50–100 predators per square foot, and maintain a habitat with pollen or yeast to sustain them. Avoid broad‑spectrum insecticides that could kill these beneficial agents.
If chemical treatment becomes necessary, choose products with low toxicity and short residual activity. Neem oil, applied at 1–2 % concentration, should be sprayed on both leaf surfaces every 7–10 days, observing a 24‑hour interval before rain. Inorganic miticides such as sulfur or potassium bicarbonate can be used at label‑specified rates, but limit applications to three per season to reduce resistance risk.
Prevent future outbreaks by rotating crops, planting resistant varieties, and maintaining soil health with organic matter. Mulch around the base of plants to conserve moisture and deter mite migration from weeds. Regularly monitor traps—sticky yellow cards placed near foliage—to track population trends and adjust management tactics promptly.
