Abstract
Potato is a very important crop in Romania, after corn and wheat and this is why this crop must be attractive for farmers through financial advantages and high yields that should feed the people. The using of herbicides is a compulsory measure for efficacy of this crop. In order to test some herbicides used for potato crop we have tested some herbicides at the Botanic Garden of University of Craiova, in 2017. There were used the following substances and rates: V1 – Stomp 5 l/ha; V2 – Stomp 6 l/ha; V3- Stomp 5 l/ha + 1 l/ha Roundup (tank mix); V4 – Stomp 5 l/ha + 1 l/ha Roundup (tank mix) and 3 l/ha Roundup, selective treatment on spots; V5- Roundup 1 l/ha, (two treatments) without any preemergent herbicide;V6 – Goal 4F 0,5 l/ha; V7 – Goal 4F 0,7 l/ha; V8- untreated control. The best results have been given by V1, 2 and 6 treatments, where there are not perennial dicots. Where Convolvulus arvensis and Cirsiumarvense are present there must be applied a 3.5 liters per hectare Roundup before potato emergence
