Abstract

A comparative study was performed concerning the action of three herbicides (Pantera 40 CE, Fusilade Super and Agil 100 EC) on onion culture. The Amstrong onion hybrid was used on clay - aluviovertic chernosem, with NPK fertilization (N80P80K80) during the preparation of the germinative bed. The unfavorable climatic conditions infl uence the effi cacy of the post-emergent applied herbicides, but signifi cant differences were recorded between variants treated with different products. When Pantera 40 CE was used, phytotoxicity phenomena materialized by temporary discoloration of the plants were not recorded, compared to the results obtained when the other herbicides were used. The use of Pantera 40 CE led to the most important production gain, with 9.8% compared to Fusilade super and 4.8% with Agil 100 EC.
