Trichogramma wasps card hang on a corn plant to control European corn borer


Tricho-Corn® is a species of Trichogramma (Trichogramma ostriniae) specifically selected for maximum results in suppressing European corn borer eggs.

To reproduce, this beneficial insect lays its eggs inside moth or butterfly (Lepidoptera) eggs. As they develop, the Trichogramma larvae kill the pest’s egg, solving the problem right at the source.

This natural method eliminates the damage corn borer larvae cause to your corn plants. You will be reducing your need for environmentally-harmful insecticides while protecting your crops.

Using Trichogramma in agriculture is safe for humans, animals, plants and the environment. It’s nature at your service!
