Plants with crop protection properties




  • © Patrick Maundu, World Agroforestry Centre Very many wild and domesticated plants have plant protection properties in some measure. Some of them are part of the rich indigenous knowledge in some parts of Africa, but others are less commonly known. The following table gives an overview of the documented species from two sources (see below) and their properties for plant protection.

    When making plant teas from these plants, please note that some have stronger effects than others and that botanicals are often difficult to dose exactly right, so you may not be getting the full benefit from any one plant tea preparation.

    For more reliable plant protection please see our new list of registered biopesticides, some of which are much more effective than conventionalspray chemicals. Also they are easy to dose correctly.
