Tomato Leaf Spray
Tomato plants, as members of the nightshade family, contain toxic compounds called alkaloids in their leaves. When the leaves of tomato plants are chopped, they release their alkaloids. When the alkaloids are suspended and diluted with water, they make an easy to use spray that is toxic to aphids, but still safe around plants and humans.
What You’ll Need:
- One to two cups of tomato leaves
- Two cups of water
- A strainer or cheesecloth
- Spray bottle
To make tomato leaf spray,simply soak one to two cups of chopped tomato leaves in two cups of water. Let it steep overnight. To make the spray, strain the leaves out of the liquid using cheesecloth or a fine strainer. Add another one to two cups of water to the liquid and add it to a spray bottle.
To use the tomato leaf sprayin your battle against aphids, spray the stems and foliage of the infested plant with the spray, paying special attention to the undersides of leaves, since that is where aphids most commonly congregate.
Caution: While this spray is very safe for humans, some people are allergic to members of the nightshade family. If you are one of them, use care in making and applying this spray. 1
