Common crops affected
Why it matters
By draining cells they cut photosynthesis and yield, and infestations flare fast in hot, dry conditions and after broad-spectrum sprays kill predators. Their webbing protects them, so early control matters.
When to act
Scout from warm, dry mid-season; manage dust and vine stress alongside treatment.
What to look for
- Stippling and bronzing of leaves, worst on stressed vines
- Webbing on undersides under pressure
- Early leaf drop reducing ripening capacity
- Dust-line hotspots along rows
How to manage it
- Reduce dust and heat stress where practical; protect predatory mites.
- Remove and destroy heavily webbed leaves.
- Spray Spider Mite Control on both leaf surfaces at 1:500; repeat every 3–5 days.
- Avoid peak-sun applications to prevent oil phytotoxicity.
