What pests attack hemp fiber?
Heartland calls hemp resilient and does not publish a pest calendar. On fiber, the loss that matters is a stand of stalks that no longer stands even.
What pests attack hemp fiber?
Heartland describes hemp as resilient to pests and disease, and neither Heartland nor rechem publishes a pest calendar or a target insect list. On fiber, look at the stand: skips, broken stalks, and plants that fall behind their neighbors. If you spray, the product has to be labeled for hemp. A corn insecticide is not automatically one.
