Aphid (Greenfly / Blackfly) Control

Aphids (Greenfly and Blackfly) are a major pest underglass. Aphids feed by sucking the sap from the plant, this stunts the growth and causes distortion of the growing point. Excess sap is excreted as honeydew, which is sticky and coats the lower leaves of your plants. Sooty mould can then develop on the honeydew. These are usually the 1st sign of an aphid infestation. To control aphids use Aphidius and / or Ladybirds / Lacewing Larvae.
