Insect Vector Control
Reduces aphid and whitefly populations that transmit plant viruses.
Since mosaic viruses have no cure, controlling the aphids and whiteflies that transmit them is the only real lever growers have. Monitoring comes before spraying here — you want to know pest pressure before deciding whether to escalate.
Step-by-step protocol
- Install yellow sticky traps at canopy height to monitor populations.
- Apply insecticidal soap (2%) or neem oil (1%) at threshold.
- Escalate to imidacloprid soil drench for heavy infestations.
- Preserve beneficial predators — spray at dusk when bees are inactive.
Frequently asked questions
Does controlling aphids stop an existing virus infection?
No — it only stops the virus from spreading to new plants. Already-infected plants need to be removed since the virus itself has no cure.
When is imidacloprid soil drench appropriate?
Reserve it for heavy infestations that insecticidal soap or neem oil haven't controlled, since it is more disruptive to beneficial insects and should be used sparingly.
