MONITORING OF THE PHYTOSANITARY STATUS OF THE HISPID STARBUR IN THE PRIMORSKY TERRITORY

Monitoring results on undesirable South American weed Acanthospermum hispidum DC conducted in the Primorsky Territory in 2020-2021 are presented. The territories of the first detections of the species in the Far East, the sites of its probable introduction connected with imported products, crops and ruderal communities were examined. Regional and All-Russian floristic check lists published for the last 30 years as well as data on the contamination of crops were analyzed. The study confirmed the status of the species as being absent in the territory of the Russian Federation. However, high probability of the entering of the pest fruits as contaminant of imported agricultural products from the countries of wide pest distribution and its successful naturalization in suitable conditions remains.
