Gazelle SG (acetampiprid) was approved for both outdoor and protected crops, said Certis technical officer Alan Horgan.
"Spinach, cress and herb growers have the opportunity to target aphid species including Myzus persicae and Nasonovia ribisnigri," he said.
"Gazelle SG offers rapid knockdown of a range of biting, sucking and chewing pests, with knockdown on some aphid species including Aphis gossypii in as little as 20 minutes.
"Its three-way contact, trans-laminar and systemic activity is useful where species are hidden within plant structures and when complete coverage isn't possible."
Growers using two applications per crop should not exceed a three-day harvest interval. For outdoor crops the interval was seven days. Applications could be made using a conventional hydraulic sprayer or a handheld applicator, said Horgan.
He advised growers to blend use of Gazelle into a programme, alternating with other products in a "recognised anti-resistance strategy".
