Aphid Control

Aphidoletes, Hippodamia (convergent lady beetles), Chrysoperla (green lacewing) larvae, Aphidius and Aphelinus are used depending on environmental conditions and aphid species. Aphidoletes are proactively introduced in low numbers onto low-level aphid populations. If aphid populations increase as growing temperatures warm up, adding green lacewings will help.  In cold weather (before it is warm enough for lacewing eggs to hatch) lady beetles, when available, are an effective predator. Aphidius and Aphelinus (specific to different aphids) are more cost-effective in greenhouses than outdoors. Insect Food and Predalure will also help draw in beneficial aphid predators. Plants with flowers will also attract lacewing adults and other beneficials. Ant control is also critical for this honeydew producing pest. Lacewing products are the most cost-effective aphid control.

Ant Control for Aphid Control

Ants will herd aphids to collect the sweet honeydew (poop).  Ants will protect aphid populations from beneficial insects.  If present, getting control of ant problems is important to control aphid problems. Click the link above or on the side to find products and information for Ant Control.

Root Aphid Control 

Preventative measures to combat Root Aphids are a growers best bet. Once established, Root Aphids can be very difficult to eliminate and can spread. Applying repeated applications of Sf nematodes and Stratiolaelaps prior to planting is the best preventative measure to combat Root Aphids. Dalotia coriaria (rove beetles) are also predators to Root Aphids.

Once established, root soaking with knock-down soft pesticides in conjunction with beneficals have been shown effective.
