Mealybug control on pepper – a two-way systemic approach with Pilaravia 155SC
Mealybugs – a hidden threat to pepper gardens
Mealybugs (scientific name: Pseudococcus spp.) are small insects that can cause serious damage to pepper if not controlled in time.
Damage caused by mealybugs:
- Suck plant sap, gradually weakening the vines
- Excrete honeydew, which favours sooty mould → black leaves, less photosynthesis
- Spread quickly via ants, tools and wind
- Cause leaf drop, flower drop and rotting of young fruit spikes
- Particularly damaging in the dry season or at the start of the rainy season
Signs of mealybugs on pepper
| Sign | What you see in the field |
|---|---|
| White powdery coating on stem nodes | Looks like mould |
| Ants crawling around the base and vines | Ants protect and spread mealybugs |
| Young fruit spikes rot and do not grow | Nutrients sucked out by mealybugs |
| Leaves turn yellow and drop here and there | The vine gradually weakens |
