Ecological control of carrot psyllid
Looking for ecological control of carrot psyllid
Are carrots able to tolerate some carrot psyllid feeding without considerable yield loss? Is it possible to develop an ecological control method of carrot psyllid based on push-pull strategy? This was recently investigated in a Finnish study.Overwintered adult carrot psyllids (Trioza apicalis) start phloem-feeding on carrot immediately after entering carrot fields, and the damage symptoms (curled leaves, stunted growth) become visible on average in two days. The migration flight from conifers to carrot fields continues for several weeks in June-July. Therefore, crop covers are the only effective method to protect the yield in organic farming.
In conventional farming several insecticide treatments are used annually to control carrot psyllids in the main carrot cultivation areas.
