Abstract:
Agrobiodiversity is an important aspect of controlling the diseases and
pests of agricultural crops. Agrobiodiversity is based on the ecological
relationships between organisms and makes full use of various control factors
in the original ecosystem. It can, therefore, significantly reduce fertilizer
and pesticide use and enhance agricultural ecosystems. This paper integrates
the control of agricultural diseases and pests and examines agrobiodiversity at
three levels; genetic diversity, species diversity and landscape diversity. The
methods, mechanisms and important factors for using agrobiodiversity to control
crop diseases and pests, and the effect of plant diversity on crop yields, are
systematically reviewed and described.
