Field vegetable fungicide Rudis (prothioconazole) has gained a new approval for control of Sclerotinia, Alternaria and powdery mildew in carrots.

The fungicide Rudis with tzt technology has gained approval for use on cauliflower and broccoli/calabrese. Its label now covers all the main outdoor brassica crops.

Crops of autumn cauliflower usually require two fungicide sprays to keep them clean through the September to December period of disease pressure. The Allium & Brassica Centre’s Andy Richardson sees Rudis (prothioconazole) fitting well as the second spray after a strobilurin-based fungicide such as Nativo 75 WG (trifloxystrobin + tebuconazole) which is often used first for broad spectrum control and white blister protection.
