Numerous pathogens and pests seriously diminish or destroy tea. In the end, it has an impact on the quantity and quality of tea produced. The diseases grey blight, brown blight, and blister blight are the most economically significant leaf diseases affecting tea in southern India. The most significant leaf blight disease is blister blight, which is brought on by Exobasidium vexans. On an annual crop basis, blister blight losses can reach 43 percent. The tea plant is attacked by a variety of pest species in addition to pathogens. The red spider mite, Oligonychus coffeae (Nietner) (Acarina: Tetranychidae), is a significant pest that significantly reduces tea crop yields. Red spider mites cause an annual crop loss of 11 to 16%. Agrochemicals have proven effective in managing these serious tea plant diseases and pests. Today, there are many serious concerns being expressed regarding environmental contamination, huge doses of chemical fertilizer, developmental resistance, and health risks. We must create alternative methods that are eco-friendly. This review article discusses how actinobacteria serve as a superior, ecologically sound substitute to dangerous agrochemicals in the tea ecosystem.
