Aphid Removal Techniques For Greenhouse Plants?

This post from Greenhouse Grower provides valuable information on how to get rid of aphids from your greenhouse. Aphids are sucking insects that damage greenhouse crops by causing curling and distortion of young, succulent growth. To control aphids, use natural aphid spray vinegar with dish soap, essential oils, neem oil, predators, repellent plants, soapy solution, reflective mulch, and reduce nitrogen.

The safest and fastest method for getting rid of aphids is to spray them off your plants with a strong stream of water from the garden hose. Avoid over-fertilizing your plants, keep them well watered, attract beneficial insects, grow plants with natural pest-repelling properties, and plant trap crops. Sugary, sticky honeydew on plant surfaces can create an ideal environment for black sooty mold growth.

Additionally, remove plant debris in the fall to eliminate overwintering locations and eliminate weeds, especially around seedlings, to stop potential transfer of aphids from one location to another. Knock the aphids off with a simple jet of water or use a spray bottle for more delicate plants.

If your plants are infested with aphids, spray white vinegar mixed with water on the underside of the leaves.
