Re: fungicide for mildew

> Sunset Garden Book has the formula: 
>        two teaspoons baking soda
>	  two teaspoons Horticultural oil
>	      for each gallon of water.

The September 1992 issue of The American Rose included an article about 
the baking soda formula developed at Cornell University. 

Here's the recipe as published there: 3 teaspoons of sodium or potassium 
bicarbonate plus 2.5 tablespoons of Safer Sunspray ultrafine spray oil. 
The article says, "Bicarbonates eliminated the fungi but a mixture of the 
bicarbonate plus oil was more effective than either agent alone. The 
spreader-sticker properties of the oil were responsible for this improved 
performance."
