Field bindweed (Convolvulus arvensis L.) and redroot pigweed (Amaranthus retroflexus L.) control in potato by pre- or post-emergence applied flumioxazin and sulfosulfuron
Field bindweed (Convolvulus arvensis L.) is one of the most serious weeds in potato (Solanum tuberosum L.), but selective herbicides controlling this weed have not been reported. A field experiment was conducted in 2010 and repeated in 2011 in Greece to study the efficacy of herbicides flumioxazin a...

A field experiment was conducted in 2010 and repeated in 2011 in Greece to study the efficacy of herbicides flumioxazin and sulfosulfuron, applied pre- or post-emergence, on field bindweed and redroot pigweed (Amaranthus retroflexus L.), as well as their phytotoxicity on potato.

Field bindweed (Convolvulus arvensis L.) is one of the most serious weeds in potato (Solanum tuberosum L.), but selective herbicides controlling this weed have not been reported.
