ADAS warns of aphid problems

Unseasonably warm autumn weather has led to an increase in aphid problems for bedding and pot plant growers, according to ADAS.

Outbreaks have been reported on crops of Bellis, Cyclamen, pansy, Viola and primrose, leading to distorted growing tips, cast skins and honeydew deposits on leaves.

Ornamentals consultant Wayne Brough said growers should be vigilant and carry out plenty of crop walks. "Growers shouldn't be complacent because before you know it you could have an issue with aphids," he warned.

ADAS has issued a reminder to watch out for Western flower thrips (Frankliniella occientalis) causing problems in Cyclamen, primrose and Bellis. Brough said growers who held summer crops late should be careful. "If you have unsold bedding plants that you held onto in August and September they can act as host plants."
