Young plant specialist Delamore has joined the ranks of suppliers to cut their offering of cutting-raised Impatiens walleriana as a result of industry wide pressure.
Following last year's outbreak of impatiens downy mildew, many across the industry took the decision to remove cutting-raised impatiens, where the problem originated, from their ranges.
Delamore managing director Wayne Eady said there had been no incidents of downy mildew in stock from Israel, where the company obtains its cuttings, or on its own nursery in Wisbech, but the company's offering had been reduced nevertheless.
"We continue to produce seed-raised impatiens, but sales are a lot slower," he said. "We still have a small offering of cutting-raised Impatiens walleriana that will go to our mail order and cash and carry only, to keep it out of the nursery production cycle."
Eady added that the problem was no longer to do with the propagators but that the disease was now endemic and will be overwintering in some places.
"We are still getting requests for cutting-raised impatiens but we have a much more limited offering. We have removed this from the nursery cycle as a result of industry pressure.
"The industry reaction to take it out of production is sensible, but some countries are still free of infection. But we have taken it away from nurseries so growers at large should be safe."
