January 16, 2012, Guelph, Ont – Syngenta Canada Inc. recently announced that Revus®Fungicide, when used in a tank-mix with Previcur N™ Aqueous Solution fungicide, has received Emergency Use Registration for suppression of downy mildew on greenhouse cucumbers in Ontario, Quebec and Nova Scotia until December 31, 2012.
“This Emergency Use Registration of Revus with Previcur N means that greenhouse cucumber growers will be able to protect their cucumbers against a very difficult-to-control and quickly spreading disease that can significantly impact yield,” stated Eric Phillips, asset lead for Syngenta Canada Inc.
Downy mildew is a disease caused by the fungus-like water mould, Pseudoperonospora cubensis, which attack only cucumbers and related crop species such as gourds, squash, pumpkins and melons. The disease primarily affects the foliage and can cause severe yield losses in a short period of time.
The initial symptoms of downy mildew typically consist of angular, yellow spots on the upper leaf surfaces. The disease can then travel to other parts of the cucumber leaf and, if left untreated, will lead to leaf kill. If even only a few spots appear on some of the leaves, this signifies that the disease is in the early stages of development and treatment is recommended as soon as possible. Since the spores disperse by air currents within the greenhouse, further disease development may be very quick under favourable environmental conditions.
Growers must apply Revus fungicide as a foliar application in a tank-mix with Previcur N when plants begin to vine or when the disease threatens. The recommended application rate is 400 mL/ha of Revus with 1.5–2.0 L/ha of Previcur N Fungicide.
