They directly damage crops by feeding, vectoring viruses, and may also cause respiratory and skin irritation to field workers. Effectively managing thrips and mites with non-toxic materials has proven to be one of the most challenging aspects of pest control. A commercial extract from the brown seaweed Ascophyllum nodosum, reduced Avocado Thrips (Scirtothrips perseae) numbers by 68% compared to the control, in field-grown Hass avocado trees. Read more…..
