Biological Controls in Organic Disease Control

Biological controls, also known as biocontrols, refer to the use of living organisms to manage and control pests and diseases in organic gardening. In the context of disease control, biological controls involve the introduction or promotion of beneficial organisms that naturally suppress or inhibit the growth and spread of plant pathogens.

How do biological controls work?

Biological controls work by harnessing the natural mechanisms and interactions that occur within ecosystems. These controls rely on the principle of using one organism to control another, creating a balance that minimizes the impact of diseases on plants.

Types of biological controls:

1. Predatory organisms:

Predatory organisms, such as ladybugs, lacewings, and predatory mites, feed on pests that cause diseases. By introducing these beneficial insects into the garden, they can help control populations of harmful pests, reducing the risk of disease transmission.

2. Parasitic organisms:

Parasitic organisms, such as nematodes and certain fungi, infect and kill disease-causing organisms. These beneficial organisms attack the pathogens directly, preventing them from causing further damage to plants.

3. Competitive organisms:

Competitive organisms, such as certain bacteria and fungi, outcompete and suppress the growth of plant pathogens. They colonize the plant’s surface or root system, creating an environment that is unfavorable for disease-causing organisms to thrive.

Benefits of using biological controls:

1. Environmentally friendly: Biological controls are a sustainable and eco-friendly approach to disease control, as they do not rely on synthetic chemicals that can harm beneficial organisms and pollute the environment.

2. Targeted control: Unlike chemical pesticides, biological controls specifically target the pests or pathogens they are intended to control, minimizing the impact on non-target organisms.

3. Long-term effectiveness: Biological controls can establish a self-sustaining population in the garden, providing long-term protection against diseases.

4. Reduced resistance: Unlike chemical controls, which pests can develop resistance to over time, biological controls offer a diverse range of mechanisms that make it difficult for pests and pathogens to develop resistance.

Considerations when using biological controls:

1. Timing: It is important to introduce biological controls at the right time, when the target pests or pathogens are most vulnerable.

2. Compatibility: Some biological controls may not be compatible with certain pesticides or cultural practices. It is essential to research and ensure compatibility before implementing biological controls.

3. Monitoring: Regular monitoring of the garden is necessary to assess the effectiveness of biological controls and make any necessary adjustments.
