Question

explain how flooding rice fields reduces the need for herbicides and pesticides in rice farming.

Explanation:

Flooding creates a water - logged environment. Most non - rice plants cannot survive in such water - saturated soil, reducing weeds (less need for herbicides). Also, many pests that are not adapted to wet conditions are deterred, reducing the need for pesticides.

Answer:

Flooding creates a water - logged environment that is inhospitable to most non - rice plants (reducing weeds and need for herbicides) and many pests (reducing need for pesticides).
