Diamond back moth

Diamond back moths are grayish in color with light diamond marks on their wings (about  ½’’ in length). Their eggs are round and yellowish white. When the conditions are right, the moths travel with the wind in early May or early summer.

The larvae are light green and live on the underside of the leaves. When the larvae are small the damage shows up as small irregular holes in the leaf.  Many larvae can destroy the whole leaf. The larva feed on leaves, buds, flower seed pods and the green outer layer of the stems.

The damage of these pests can be extremely costly. Keep an eye out on your field and you will save your yield. Our agronomists can help you determine the economic threshold of an application of insecticide.
