Use of Beneficial Soil Microbes to Improve Plant Growth | Indogulf Micro-organisms such as bacteria, fungi, viruses, and protozoa can be used to protect plants, as some of them are parasites or pathogens of insects or other organisms that are pests or cause disease in plants.

What microorganisms help plants?

In their natural environment, plants are part of a rich ecosystem including numerous and diverse microorganisms in the soil. It has been long recognized that some of these microbes, such as mycorrhizal fungi or nitrogen fixing symbiotic bacteria, play important roles in plant performance by improving mineral nutrition.

How do microbes protect plants? soil microbes lend the entire plant a special kind of disease protection. When soil microbes are present, plants undergo what is called “induced systemic resistance,” an immunity boost that protects the plant from a broad range of pathogens.

What protects plants from bacterial infection?

The Plant Cell. All plant tissues contain pre-formed structural barriers that help limit pathogen attachment, invasion and infection. The cell wall is a major line of defense against fungal and bacterial pathogens.

Which is the best method of plant protection?

There is a wide range of disease protective measures: • • • • • • • •

use of nitrogen fixing bacteria planting of disease-resistant varieties; introduction of quarantine for infected plants; constant monitoring and prediction of plant conditions; the heat treatment of plants; crop rotation; deep plowing; burning the remains after the harvest.

What microorganisms are used in agriculture?

Some of the commonly promoted and used beneficial microorganisms in agriculture worldwide include Rhizobia, Mycorrhizae, Azospirillum, Bacillus, Pseudomonas, Trichoderma Harzianum, Streptomyces species and many more.

What effect does Trichoderma have on plant growth?

Trichoderma spp. significantly suppress the growth of plant pathogenic microorganisms and regulate the rate of plant growth.

Common plant disease such as root rot disease, damping off, wilt, fruit rot and other plant diseases can be controlled by Trichoderma spp.

Role of Nitrogen-Fixing Microorganisms for Plant Growth Nitrogen fixing bacteria can indirectly affect the soil nitrogen pool and enrich microbial diversity in the soil to support soil health.
