Brian, I hear you. Lots of fungicide/insecticides have been taken off the Canadian market. My nurseryman warned me, and I did get some extra on my last purchase over a year ago. So I still am using Funginex and Cygon, and when it is finished, I will be in the same boat as you and many Canadians are already. Funginex and Cygon/Lagon where a systemic product. I do not believe there are any more systemics on the market.

So if anyone hears of something that works, Please enlighten us. So far, I do not think there is anyone who I have talked to have found a successful substitute. I live in a heavily black spot area, so for me it is spray, or no roses. I rarely use the systemic insecticide anymore, I just squish what critters (aphids) that I can. But I do need to be on top of black spot. If there really is not a good substitue, then I will go back to using an egg spray as a fungicide.

Would like to hear from other Canadian rose growers as to what they use. Thanks for bringing this up Brian.

I used the last of my Floritect last week and was told it's unavailable. Luckily we are just over the border from Detroit so possibly can get some there. In the meantime I have been advised to use Neem Oil or a solution of potassium bicarbonate which is currently available as GreenCure www.greencure.net
Hope this helps.

I have tried a number of the low-tox fungicide products and home remedies. In my experience, micronized sulfur is the most effective. It is very effective as a mildew preventative and fairly effective against blackspot. It is also a rust control, but I have no experience with rust. To control blackspot under bad conditions, sulfur must be applied faithfully, starting before the disease is widespread. Before synthetics, people grew susceptible roses using either sulfur or bordeaux mixture.

The big thing about sulfur is it is incompatible with anything oily or with weeks-old oily residues on foliage. So if you are going to try sulfur, don't apply neem or any other oil. Soap can replace oil as an insecticide/miticide with similar effectiveness.

Sulfur products are widely available in Canada.
