Recent advances in the natural products-based lead discovery for new agrochemicals

Abstract

Crops will be harmed by fungi, pests and weeds during their growth. In the past half century, scientists have conducted in-depth research on natural products extracted from microorganisms, plants or animals, and used natural products and their derivatives as the lead for pesticides discovery. Natural product pesticides have the advantages of easy degradation in the environment, selective control and safety to non-target organisms. This review summarizes the studies on natural products pesticides in recent years, including natural products of chemical modification and biosynthesis, mainly fungicides, herbicides, insecticides and acaricides. We classify natural products according to their active fragments, and discuss their effects on the control of agricultural fungi, pests and weeds. Ultimately, we found that lead discovery based on natural products has great advantages in pesticide development.
