The backbone of many nations with agrarian economies worldwide is agriculture. There are many difficulties in feeding the world’s growing population today. The attack of insect pests is a significant concern, among other factors, and contributes to the low production of agronomic crops. Currently, agronomic crop pests and diseases are controlled with a variety of chemical methods, including fungicides and insecticides. However, concerns about agronomic sustainability have led to the broad and extensive use of integrated techniques for disease and pest management. Biopesticides are essential for environmentally sound practices and sustainable agriculture. They provide a natural alternative to synthetic pesticides for pest management by targeting pests by living organisms such as fungi, bacteria, or plant extracts. Actinobacteria are among the most potent tools in sustainable agriculture, offering a natural and efficient substitute for synthetic/chemical pesticides while promoting plant resilience and soil health. This study revealed that the use of actinobacteria was the most effective way to control agronomic pests and increase the yield of agronomic crops.
