Baking Soda as a Pesticide

[ZandraJoi]

Hi thanks for the answer can you let me know who much can mix in a liter of water or any other liquid. I had some white flies and other worms on few plants so want to utilize Toxin free liquids to kill them.

I go by the gallon. A gallon of water, 1T baking soda, 1T vegetable oil, few drops liquid soap. Shake well & spray on.
There's almost 4 liters to a gallon so you would have to divide the ratio by 4.
If it doesn't help, you can add in 1 to 2T Neem oil to the gallon of water.
