Ingredients include concentrated d- limonene, clove oil, cinnamon oil, vinegar, and citric acid. These herbicides are non-selective and non-systemic, meaning any plant sprayed will be affected, and they kill the above surface foliage of plants.
Synthetic herbicides can "select" which types of plants the chemicals will effect. Organic herbicides cannot do this and so are "non-selective."
Synthetic herbicides go into the system of plants, organic herbicides do not, and so are "non-systemic."
