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.

How soil microbes help plants resist disease - Indogulf
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
