Damage symptoms
Damage is caused by the mites sucking out the contents of plant cells. Hemp russet mite develops on the stems and petioles of the hemp plant and can cause stunting. When populations are large, the mites can also be found on the underside of leaves. This results in smaller leaf size and suppressed bud growth leading to a reduction in the number of buds and dwarfed buds. This damage can reduce yield and quality. Other signs of damage include dull, greyish, or bronzed leaves and upward curling of leaf edges.
