Bacillus Subtilis
Bacillus Subtilis
At present, the use of biological or biological methods to control plant diseases. By living things Including microorganisms Plant pathologists and farmers have taken a lot of attention. Because the use of microorganisms is safe for people, plants, animals and the environment. Bacillus bacteria It is accepted in various groups for the control of a wide variety of plant-causing fungi. Which at present, both at home and abroad have been produced Bacteria Bacillus In trade then Bacillus subtilis Which is used to control various plant diseases This group of bacteria can be found naturally, and is especially abundant in soil, plant surfaces and high carb food sources. In Thailand, there has been research on the use of antagonistic microorganisms. It has been continuously used in plant disease control and can be developed into many kinds of biologicals. And it can also be used to control pests effectively. Equivalent to using chemical pesticides
The nature of Bacillus Subtilis
Bs Are bacteria in gram-positive, rod-shaped Spores are created. And have different cell sizes 0.5 x 1.2 - 2.5 x 10 μm The endospores are different in shape depending on the type of infection. And can produce many types of enzymes, such as amylase and protease Can be found naturally Grow to be able to have a wide variety of food They can also thrive in little or no air. B. subtilis It is considered a microorganism that does not cause disease to humans and animals.
leadership Bacillus Subtilis To control plant diseases
This group of bacteria is suitable for disease control because
- Able to compete with germs And can also absorb nutrients better than other microorganisms when they are in bad environment.
- It is a microorganism that is safe for people, plants and animals.
- It is very resistant to environmental conditions. Good resistance to hot and humid environments
- Can be used to control plant diseases such as blight disease, dry leaf disease, dry leaf sheath disease from fungi
