What it is / How it shows up:
Aphids are often mentioned in gardening forums and cannabis cultivation guides. These tiny insects, which come in various colours like green, black, and white, cluster on the undersides of leaves. Aphids feed on plant juices, weakening the plants and potentially transmitting diseases. Cannabis growers may notice sticky residue or sooty mold on their plants, both signs of aphid infestation. These pests multiply quickly, making early detection crucial for effective management.
How it’s measured or identified:
- Visual inspection of leaves and stems for clusters of insects.
- Presence of sticky honeydew on leaves.
- Leaf yellowing and curling.
