White rust on spinach

May 14, 2012, Dorchester, Ont – The Pest Management Regulatory Agency (PMRA) has granted a User Requested Minor Use Label Expansion (URMULE) for Ranman 400SC fungicide. Suppression of white rust on spinach has been added to the product label.                                                                    

White rust is a common disease of spinach that has been on the rise in some parts of Canada over the last few years. Ranman fungicide is a Group 21 product with the active ingredient cyazofamid and is also registered for use on carrots, cucurbits and potatoes.

“The addition of white rust to the Ranman product label is an important step to providing spinach growers with the tools needed to effectively manage production of their crop,” says Janet Porchak, national marketing manager with UAP Canada Inc., distributors and retailers of Ranman fungicide in Canada.


Porchak notes that the work to add white rust to the product label dates back a few years and is the result of collaboration between the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), growers and extension personnel, as part of the ministry’s minor use program.

Ranman fungicide can be used at a rate of 0.15 to 0.20 litres per hectare in 300-500 litres of water per hectare.  

David Strilchuk, Canada country manager with FMC Corporation, the marketers of Ranman in Canada, says the product should be applied on a seven-day schedule starting when conditions are conducive to disease development or when disease is first seen.

“Ranman can be applied up to five times per year and has a one-day pre-harvest interval requirement.”

Strilchuk says Ranman fungicide should also be used as part of an Integrated Pest Management program and in rotation with other disease management products as part of an effective resistance management strategy.
