Aphids symptoms and treatment
Also known as greenfly and blackfly, Aphids are a common sap-sucking garden pest.
Symptoms of Aphids
- Decreased growth rates
- mottled leaves
- yellowing of the plant or leaves
- stunted growth
- curled leaves
- browning
- wilting
- low yields of fruit
- death of the plant occurs if the aphids overcome the plant
Remedies for Aphids
- Biological control – introducing a natural aphid predator such as Lacewing, ladybugs or hoverfly via seeding eggs / larvae on the plant.
- Encourage aphid predators by planting flowers and plants such as tagetes, sunflower and morning glory around the affected plants.
- Remove via water spray (take care not to overwater the plant) this is effective only when aphid infestation is minimal
- Garlic spray – mix minced garlic with detergent and leave to brew for a week, apply to leaves and stem using a spray bottle.
- Diluted detergent / washing up liquid – spray every week or so
- Remove and squish aphids with fingers.
- Insecticidal soap (a potassium-salt soap is available at most garden centres).
- Neem and lantana products can be helpful and are eco-friendly
- Biological Insecticides based on Beauveria bassiana or Paecilomyces fumosoroseus.
