Aphids and How to Protect Your Crop

Aphids

03 April 2020

Aphids have become a severe problem in the agricultural and horticultural sectors. As aphids are able to reproduce asexually and are notorious virus vectors, they have quickly become one of the most threatening greenhouse pests. For a long time, in crops where natural enemies had been released against other pests, aphids could be controlled effectively by means of selective chemical pesticides, with few adverse effects on biological controls. However, due to increased resistance to pesticides, biological control is becoming the preferred method of controlling these pests.

Overview of Aphid Plant Damage

Aphids excrete honeydew, which attracts mold. Mold not only spoils the crop, but reduces photosynthesis which can stunt growth and reproduction. Toxic substances can be transmitted into the plant.

As a result of their enormous reproductive capacity, aphid infestations develop rapidly. Koppert has developed multiple products to control aphids at all levels of infestation. Aphipar, Aphidius colemani, and Ervipar, Aphidius ervi, parasitic wasps are effective as preventative measures, as well as, controls in heavily infested areas. For extra support in heavily infested areas, Koppert produces several products for added control. These supplemental products are designed to work in conjunction with both Aphipar and Ervipar and allow for control in varying crops and climates.

Monitor Your Crop!

For biological pest control to succeed, crop monitoring is essential. Horiver and Rollertrap units ensure monitoring is efficient with regards to both time and cost.
