Organic farmers control pests by maintaining a balanced ecosystem where pests are kept at manageable levels without eradication, using natural predators and biocontrol methods. Conventional methods use chemicals that kill pests and beneficial organisms indiscriminately. Organic farming avoids toxic pesticides, promoting ecological balance and reducing chemical dependence.
