1. Use of beneficial microorganisms: Beneficial microorganisms such as bacteria, fungi, and viruses can be used to control plant pathogens. These microorganisms can compete with pathogens for resources, produce antimicrobial compounds, or induce systemic resistance in plants.
2. Crop rotation: Rotating crops can help break the life cycle of pathogens by depriving them of their host plants. This practice can also help improve soil health and reduce the buildup of pathogens in the soil.
3. Resistant varieties: Plant breeders have developed crop varieties that are resistant to specific pathogens. Planting resistant varieties can provide direct protection against pathogens, reducing the need for chemical controls.
4. Biopesticides: Biopesticides are naturally occurring substances derived from plants, animals, or microorganisms that can control plant pathogens. These products are often less harmful to the environment and non-target organisms compared to synthetic pesticides.
5. Physical barriers: Physical barriers such as row covers, mulches, and barriers can be used to physically prevent pathogens from reaching plants. These barriers can also help create a microclimate that is less favorable for pathogen growth.
6. Sanitation practices: Proper sanitation practices, such as removing infected plant debris, sterilizing tools, and cleaning greenhouse surfaces, can help prevent the spread of pathogens within a growing area.
7. Integrated pest management (IPM): IPM is a holistic approach to pest management that combines multiple control tactics, including biological, cultural, and chemical controls. By using a combination of strategies, growers can effectively manage plant pathogens while minimizing the impact on the environment.

Seven Biological Control Practices for Direct Plant Protection from Pathogens
Before Infection:
1. Biofumigation: Using bioactive compounds released by certain cover crops, such as mustard and marigolds, to suppress soilborne pathogens and promote beneficial microbial communities.
2. Biological Seed Treatment: Applying beneficial microorganisms, such as bacteria and fungi, to seeds to protect them from seed-borne pathogens and enhance seedling establishment.
3. Companion Planting: Intercropping susceptible plants with resistant companion plants to provide a physical barrier, release antimicrobial compounds, or attract beneficial insects that prey on pathogens.
4. Mycorrhizal Inoculation: Introducing beneficial mycorrhizal fungi to plant roots, which enhance nutrient uptake, increase drought tolerance, and strengthen plant defenses against pathogens.
After Infection:
5. Microbial Antagonism: Using beneficial microorganisms to produce antibiotics, lytic enzymes, or other inhibitory substances that directly target and kill plant pathogens.
6. Induced Systemic Resistance: Stimulating plants' own defense mechanisms by applying elicitors, such as certain bacteria or plant extracts, to enhance resistance to subsequent infections.
7. Biocontrol Agents: Releasing or applying specific natural enemies of plant pathogens, such as predatory nematodes, insects, or fungi, to suppress pathogen populations and protect plants from disease.
