Reducing crop losses, minimizing pesticide use, avoiding pesticide residues, increasing farmer's income and enhancing environmental health are the hallmarks of sustainable agriculture. How can this be achieved through the use of green pesticides? Green pesticides refer to all types of nature-oriented and beneficial pest control materials that contribute to reduce the pest population and increase food production. They are safe and ecofriendly. They are more compatible with the environment components than synthetic pesticides. Eminent scientists have highlighted the importance of green pesticides and discuss their research findings in this volume.
