Plants for Biocontrol and Biological Control of Plant Pathogens

For maintaining the quality and quantity of food produced around the world, the plant diseases are needed to be controlled. To prevent and control plant diseases, different methods may be employed including chemical fertilizers and pesticides which have significantly improved the crop productivity and quality over the past many years. However, there are strict regulations on the use of chemical because of its hazardous effect. But some pest management researchers have developed alternatives which are referred to as biological controls for controlling pests and diseases by the application of biocontrol plants and also by the use of plant–microbe interactions for controlling plant pathogens. This chapter focuses on the various plants which are used for biocontrol and how they can be helpful in sustainable development. Similarly, how to use microbes and other organisms for the control of plant diseases has also been studied in detail.
