The use of botanical insecticides (such as pyrethrum, which is derived from chrysanthemum flowers) has a number of advantages over synthetic insecticidal compounds, including increased safety from phytotoxicity, short residual persistence, less risk of the formation of pesticide resistance, and often include OMRI Listing for organic use. Botanically derived insecticide active ingredients such as pyrethrum can increase worker safety due to shorter re-entry and pre-harvest intervals and are an excellent choice for incorporation into an Integrated Pest Management (IPM) program.
