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

This was a great ides for farmers! here's why..
Even though rice is a type of grass It can grow in wet floody conditions and dry dirt conditions. But When they grow in dry ground  So do all the of the weeds. And the weeds takes away quality from the rice. 
On top of that there is not a single herbicide out there that can kill the weeds and not kill the rice:/
On top of that flooding kills a lot of the bugs that are trying to get a meal. If they cant swim then there might be a problem for the bugs:D
anyways hope this is helpful and pick me as BRAINLIEST:)

Nimbostratus is the correct answer.
