Microtech TX activator is a complex pool of microorganisms activated with a special organic matter that plays a strong action against several phyto-pathogenic fungi in different ways:
- a rapid rhizosphere colonization through the competition for space and nutrients engaged with pathogenic fungi to reduce their development;
- a production of chitinolytic enzymes that penetrate the host, so the pathogen is used as nourishment;
- a production of fungistatic substances that prevent pathogen development limiting the occurrence of infections;
- a plant growth stimulation with an increased roots, leaves and stems production and an improved efficiency in both macro and micro-nutrients absorption.
This special soil microbes complex, thanks to the production of toxic metabolites, plays a good antagonistic activity against several soil-borne pathogens. It is also able to occupy and remove forms of pathogen resistance, such as sclerotinia.
Microtech SX Activator complex is made of a group of microorganisms with intermediate characteristics between fungi and bacteria that have a joint activity and lead to an increased plant root development. The growth-promoting activity is carried out through several processes: one of the most significant is the release of hormone-like substances that stimulate cellular proliferation and multiplication, as well as roots growth in the rhizosphere; it is also able to chelate iron and other micro-elements by producing organic acids known as siderophores. This activator stimulates the production of many useful plant substances, such as siderophores (organic substances that chelate iron), micro-elements, vitamins, amino acids and organic acids. It promotes plant development and it is characterized by the ability to produce antibiotic substances (streptomycin) which control many root system pathogenic fungi (Pyrenocheta lycopersici, Fusarium oxysporum, Pythium ultimum, Verticillium dahliae, Phytophtora capsici, etc.). The antagonistic activity against phytopathogens is not only managed by a direct process, but it is also performed by space occupation and competition for nutrients.
Microtech SbX genus belongs to the group of PGPR and includes species of bacteria isolated from the rhizosphere with several beneficial activities. Many studies have proved that these bacteria help plants overcome stresses caused by different phytopathogenic fungi that attack both the aerial system (Alternaria, Botrytis cinerea, Powdery mildew, Bremia and group Peronosporaceae, Moniliaceae) and the root system (Phytium , Rhizoctonia, Fusarium and Sclerotinia). This activity is carried out through several processes such as degrading enzymes’ production (chitinolytic, glucanolytic and proteolytic enzymes) secreted when bacteria approach the fungus; they stimulate plant self-defenses and compete with pathogens to achieve space and nutrients. In addition, Microtech SbX genus’s species promote plant growth by producing phytohormones and phytohormonal action substances.
Microtech PX is a high concentrated activator containing multitasking microbes which provide an antagonist activity against nematodes. The nematode biocontrol activity is related to the production of ring structures that swell and trap nematodes passing through. Then the nematodes are enzymatically degraded and used as nourishment by the fungus. A Microtech PX could be a significant biological means of controlling pathogenic nematodes such as Meloindogyne and Heterodera genus. Some tests have proved that the use of these fungi on soils (previously sterilized by chemical agents, solarization, steam) maintained the nematodes level below the damage threshold for more years compared to soils without fungi, thanks to the “biological vacuum” filling action.
Microtech MX is a mix of pathogen fungi that can penetrate into the host insect through its exoskeleton by producing chitinolytic enzymes. Once the fungus is inside, it develops and eats the host. Infected but still alive insects have limited movements, they are unable to eat and represent a source of infection for other insects.
