Neem extract and neem oil are not the same thing. Also, I don't even know what this has to do with anything anyone has said?

Because baking soda is only effective against powdery mildew and only mildly so, and tomatoes are susceptible to a range of very unrelated fungal and bacterial diseases. In addition, the recommendation to use it is an extrapolation of the effectiveness of potassium bicarbonate. Unfortunately, a logical extrapolation doesn't equal a scientific or in vivo reality.
