Abstract
The cardoon (Cynara cardunculus L. var. altilis DC.) is an herbaceous perennial plant species, belonging to the Asteraceae family, which is native to the Mediterranean area.
It can grow up to two meters high with thick and rigid stems that can be up to 3 m high and about 2-4 cm of diameter, branched, with alternate, sessile leaves.
The inflorescences, called capitula or heads, consists of several hermaphrodites and tubular flowers and the fruits are achenes, shiny and dark in color in which the oil-rich seeds (25 g 100 g‑1 D.W.) are enclosed.
This crop can be used as a source of bio-energy, but also to produce fiber, fodder and bio-intermediates for industrial processes.
The roots can be used for production of inulin that is used as an alternative low-calorie sweetener.
To the aim of defining protocol of weed control in the first year of cardoon planting, in 2018-2019 and 2019-2020, field experiments at farms located in Terni (TR, Italy) were carried out to test the efficacy of three herbicides for weed control.
In the 2018-2019 season, metobromuron, pendimethalin and aclonifen were tested in pre-emergence of cardoon; in the 2019-2020 season, metobromuron was replaced S-metolachlor.
The results obtained generally showed the efficacy of the products tested in the control of the main annual dicotyledonous weed species; no significant differences in efficacy were observed among the different herbicides.
The findings of this work can contribute to improved weed management of cardoon because the combination of ‘frequent use’ and ‘similar mode of action’ is the most important factor in the development of herbicide resistance.
Therefore, the use of herbicides with different mechanisms of action (HRAC, 2023) can improve weed control.
