LITCHFIELD, Mich. – Downy Mildew disease on Impatiens wallerana is increasingly a concern for greenhouse growers, and the evidence is indicating that growers need to take this disease seriously. 

To help grower customers battle this devastating disease, Raker has initiated a preventative disease control program. All Raker Impatiens wallerana will be treated preventatively prior to shipment for the disease, and growers can be assured their product will be protected when they receive it. Growers are strongly advised to continue a preventative program as part of their production plan. 

There are many articles available online that give specific information about the identification, transmission, and factors that increase/decrease the probability of infection. In addition, there is good advice on preventative programs to use. Below are two recent references:
