How to Identify and Control Aphids on Cannabis Plants

Aphids Description
Most of the time aphids are wing-less, but in spring and fall aphids can have wings to increase their dispersal.
These are small insects that can be found in large numbers that can be in clusters.



Aphids Identification on Plants
Aphids can produce, honeydew a sugary secretion, which often turns black with the growth of a sooty mold fungus.
Some aphid species inject a toxin into plants, which causes leaves to curl and further distorts growth as well as transmit viruses.



Managing Aphids
Reflective (silver) mulch can be used to not allow the aphids to easily detect the underside of the leaves.
Garlic sprays can help repel them from initially entering an area.

Beneficial insects such as green lacewings and lady beetles can be effective if established early.
