How do organic farmers control pests?

उत्तर
Organic farmers control pests by maintaining a balanced ecosystem where pests are kept at manageable levels without eradication. They use biological control methods, relying on natural predators and parasites. For example, ladybirds control aphids, and dragonflies control mosquitoes. This approach avoids chemical pesticides, preserving beneficial organisms and reducing environmental harm.
