Currently, the widespread application of pesticides to treat plant diseases pollutes the environment day by day. Given the rising environmental pollution issues brought on by a greater understanding of the drawbacks of the widespread application of agro-chemicals, eco-farming is now identified as a key area on a global scale. It is possible to manage plant diseases using biological, cultural, and conventional methods. Although synthetic pesticides do contribute significantly to the suppression of the plant disease, their adverse effects on people and soil biodiversity make it important to utilise biological control techniques in their place. These strategies involve using various antagonists, like fungus and bacteria, as well as combining them.
