ABOUT
Hemiptera is a large group of insects with a typical mouthpart causing direct damage to plants by feeding on sap from the plant tissue. This group contains major pests of crops and important vectors of infectious diseases.
How to treat?
- Biological
Remove pests mechanically. Rub the pests off, or remove infested parts or use a strong stream of water to remove the insect.
Apply ecological products for plant protection (e.g. soap sprays, neem oil, horticultural soap).
Introduce natural enemies - predators, parasites, or diseases (e.g. lady beetles, lacewings, parasitic wasps).
Isolate the infested plant immediately to avoid the infestation from spreading.
- Chemical
If necessary, apply insecticide containing imidacloprid (GHS07: Harmful, GHS08: Health hazard).
If necessary, apply insecticide containing deltamethrin (GHS06: Toxic, GHS09: Environmental hazard).
If necessary, apply insecticide containing lambda-Cyhalothrin (GHS06: Toxic, GHS07: Harmful, GHS09: Environmental hazard).
- Disease prevention
Encourage the presence of natural enemies (e.g. lady beetles, lacewings, parasitic wasps).
Apply dormant oil (controls pests and diseases during the off-season).
Inspect new plants for signs of an infestation. Inspect the underside of leaves and stem joints.
