AN EVALUATION OF HERBICIDES FOR FIELD CULTIVATION OF CROCUS
The results obtained indicate that most of the examined preparations can be used. It was that the preparations used in higher doses worked longer and better controlled weeds up to the last stage of crocus cultivation. In autumn, the most successful herbicides were the following: Racer 4 1/ha, Azotop 2.5 kg/ha, Buracyl 2.5 kg/ha and in spring Bladex 50 WP 2 and 3 kg/ha and Goltix 10 kg/ha. The efficiency of Basagran applied a week before bulbs harvesting was low.
In this way the herbicides did not have any negative influence on the total yield in units per 1 m2. A decline of bulb weight in the total yield on plots treated with Bladex 50 WP was observed. The highest crop of marketable bulbs was obtained from plots treated with Racer (fluorochloridon).
