Status of the biopesticide market and prospects for new bioherbicides.

Biopesticides (commonly called Biocontrol or more recently bioprotection) have been experiencing double digit growth and now comprise about 10% of the global pesticide market driven by increased return on investment, restrictions on chemical pesticides, and pesticide resistance and residue management. However, despite the large need for new herbicides due to widespread and increasing resistance to herbicides with almost most of the chemical modes of action, bioherbicides are an insignificant percentage of the total. The technical difficulty in finding bioherbicides that can compete with the spectrum and price of chemical herbicides has left agriculture with a paucity of new bioherbicides. Billions of dollars of investment capital are being invested in new, innovative startups, but only a small number focus on bioherbicide discovery and development, due to a perception of higher risk than plant biotech, biostimulants, bionutrients and other categories of biopesticides. However, the exciting new technologies that these startups are developing such as RNAi, sterile pollen, and systemic metabolites have potential to impact the market in 10 years or less. © 2023 Society of Chemical Industry.
