Strobilurin fungicide Amistar from Syngenta has been granted full on-label approval from the Pesticides Safety Directorate for use on carrots, leeks and onions for the 2002 season. This extends its on-label approvals from peas gained last year, and specific off-label approval for a range of other vegetable crops.

Syngenta believes its product boosts crop yields and 'optimises quality traits.' The company's vegetable manager Bruce McKenzie said: 'Disease control options for vegetable growers had been getting ever more restrictive with the EU pesticide review. The availability of Amistar with its broad-spectrum activity and novel mode of action will now prove an essential part of all fungicide programmes. On these crops.' The new label for Amistar covers downy mildew on bulb onions, alternaria and powdery mildew on carrots and rust and purple blotch on leeks.
