Common crops affected
What is it?
Leaf curl viruses are plant viruses (many in the begomovirus group, such as tomato yellow leaf curl virus) transmitted primarily by whiteflies, with some curl-type problems linked to aphids or thrips. The virus disrupts normal growth, causing curling, yellowing, and severe stunting. Infected plants remain infected and act as a reservoir.
How to identify it
- Upward or downward curling and crumpling of leaves, especially new growth
- Yellowing leaf margins and overall stunting
- Reduced flowering and fruit set; small, sparse fruit
- Spread that follows whitefly activity through the crop
Damage and how it spreads
Leaf curl viruses can severely stunt plants and slash yield, sometimes destroying a crop, and they cannot be cured. Because whiteflies (and in some cases aphids/thrips) drive the spread, the effective response is aggressive vector control plus removal of infected plants — not a spray aimed at the virus itself.
How to control it
- Control whiteflies (and other vectors) aggressively, especially early in the crop.
- Use resistant varieties and virus-free transplants where available.
- Remove and destroy infected plants promptly.
- Use barriers, traps, and weed management to reduce vector pressure.
Recommended Vegalab solution: Spider Mite Control
No product cures a plant virus, so the honest, effective approach is vector control and sanitation. Vegalab Spider Mite Control controls whiteflies, aphids, and thrips that transmit leaf curl viruses, and MultiMite Control broadens coverage. Combine vector control with resistant varieties, prompt removal of infected plants, and trapping. Supporting plant resilience with Armour Boost helps healthy plants tolerate pressure.
| Role | Product | Use |
|---|---|---|
| Primary control | Spider Mite Control | Contact miticide / insecticide |
| Companion / broader pressure | MultiMite Control | Broader mixed mite & insect pressure |
| Plant support | Armour Boost | Silica for tissue resilience |
Preventing it next season
Control whiteflies from the start, use resistant varieties and clean transplants, trap and monitor, manage weeds, and remove infected plants early. Strong, resilient plants cope better — support them with Armour Boost.
