Abstract
The results of experiments carried out in Bonin in the years 1996–1998 to assess the efficacy of a herbicide Sencor 70 WG in controlling weeds in potato crops are presented. The herbicide was applied in different doses either prior to potato emergence or after emergence. The greatest efficacy of Sencor 70 WG application was observed when the herbicide was used in a single dose of 1 kg/ha in the preemergence period or in a divided dose, including 0.3 kg/ha and 0.2 kg/ha in the preemergence and after emergence periods, respectively. The phytotoxic effects of plants treatment with Sencor 70 WG were largely diminished when the herbicide was applied in divided doses.
