If they recommend potassium chloride for bananas, it probably will not harm them (but it may be wrong!). I haven't tried a chloride salt on my bananas before so I don't know if it causes any harm.
Plants like tomatoes will be heavily harmed while others such as prickly pear cactus will be fine.
Sul-Po-Mag is great due to the fact that high potassium concentrations can cause a deficiency in magnesium. I use a mixture of potassium sulfate and magnesium sulfate. Another chemical you can look for is potassium nitrate but it may be harder to find since it's an oxidizer. I know I've seen all of the above on Ebay but you'd have to pay shipping of course.
