Bacillus amyloliquefaciens
![](../../static/picture/05.jpg)
Bacillus amylolyticus has a strong disease resistance and bacteriostatic effect. It can secrete more than ten kinds of lipopeptide antibiotics and other antifungal active substances, mainly antifungal proteins and surfactants. These secretions interact with the lipid membrane of the virus physically and chemically, destroying the membrane structure, resulting in the release of intracellular solutes of harmful bacteria and eventually causing cell death. It can effectively inhibit the activity of plant pathogenic fungi and has strong bacteriostatic effect, It can also inhibit sclerotia germination and mycelial growth of Sclerotinia sclerotiorum.

Bacillus cereus
![](../../static/picture/08.jpg)
1.Competition is to seize nutrients through the competitive sites between endophytic bacteria and pathogenic bacteria, thus inhibiting the occurrence of plant diseases. The pathway and mode of Bacillus entering the plant are basically similar to that of the pathogen. After entering the host body, Bacillus preferentially occupies the invasion point of the pathogen and competes for nutrition with the pathogen.
2. Antagonism Endophytic bacteria produce antibacterial substances through assimilation to inhibit the growth of pathogenic bacteria or directly kill pathogenic bacteria. Bacillus can secrete a variety of antifungal and bacterial antagonistic substances (new antifungal cyclic polypeptide APS). These substances have a broad antibacterial spectrum and long-lasting antibacterial effect, and have a significant inhibitory effect on spore germination and hyphal growth of pathogenic fungi.
3.Induced plant resistance
(1) Bacillus can induce the host plant to produce some physical and structural resistance, and deposit a large amount of wood and phenolic substances at the parts where the pathogen attempts to invade, so that the cell wall of these parts is thickened, thus effectively preventing the invasion of the pathogen.
(2) Bacillus can also induce physiological and biochemical changes of host plants, accumulate relevant proteins, and produce hydrolases and oxidase (such as chitinase β- 1.3 glucanase and peroxidase) to inhibit the growth of pathogenic bacteria.
(3) Bacillus cereus can secrete superoxide dismutase (SOD) and make plants resistant to pathogenic bacteria.
Trichoderma harzianum
![](../../static/picture/09.jpg)
1. Competitive effect: Trichoderma harzianum grows rapidly around the root and leaf circumference of the plant, seizing the site on the surface of the plant, preventing the pathogenic fungi from contacting the root and leaf surface of the plant, so as to protect the root and leaf of the plant from the infection of the above pathogenic bacteria. 2. Heavy parasitism: in the process of interaction between Trichoderma harzianum and pathogenic bacteria, the metabolites secreted by the host hypha make Trichoderma harzianum tend to grow towards the host fungi, and the host is recognized by Trichoderma harzianum, and the parasitic relationship will be established. After Trichoderma harzianum recognizes the host fungi, Trichoderma harzianum filaments grow in parallel and spiral winding along the host hypha, and produce attached cellular branches that are adsorbed on the host hypha. By secreting extracellular enzymes, Trichoderma harzianum dissolves the cell wall, penetrates the host hypha, absorbs nutrients, and then kills the pathogenic bacteria. 3. Antibiotic effect: Trichoderma harzianum secretes some antibiotics, which can inhibit the growth and colonization of pathogenic bacteria and reduce the harm of pathogenic bacteria. 4. Plant growth regulation: Trichoderma harzianum colonizes plant roots and produces compounds that stimulate plant growth, improves the microenvironment of roots, enhances plant growth and disease resistance, and improves crop yield and income. 5. Inducing plant resistance and initiating plant defense response
Trichoderma harzianum metabolizes and produces xylanase. Under the action of xylanase, plants have obvious defense reaction, K +, H +, Ca2 + ion channels open, ethylene synthesis and PR protein accumulation. Trichoderma harzianum produces chitinase and β- 1,3-glucanase plays an important role in plant pathogenic fungi. Trichoderma harzianum starts the plant defense response, leading to the production and accumulation of phenolic compounds and lignin related to disease resistance. The protease produced at the same time can degrade the pathogen that digests the plant cell wall, directly inhibit the germination of the pathogen, inactivate the enzyme of the pathogen, and prevent the pathogen from invading the plant.
Paecilomyces lilacinus
![](../../static/picture/10.jpg)
1.Promote plant growth
Paecilomyces lilacinus can produce rich derivatives, such as indole acetic acid products. The most significant physiological effect is to promote the growth of plant roots and plants at low concentrations. The colonization of Paecilomyces lilacinus in plant roots can not only significantly inhibit nematode infection, but also promote the growth of plant vegetative organs, and also promote the germination and growth of seeds.
2. Paecilomyces lilacinus produces a variety of functional enzymes. Chitinase can degrade chitin. It can promote the hatching of Nematoda eggs and improve the parasitism rate of Paecilomyces to nematodes. In addition, it also produces cell lysis enzyme, glucanase and silk protease to promote cell division.
3. Degradation effect
Paecilomyces lilacinus can promote the dissolution of insoluble phosphate, the solubilization effect of Paecilomyces lilacinus is 30%, and the antagonism of nematodes is 20% ~ 40%.
4. Paecilomyces promotes the decomposition of many chemical polymers (such as pesticides, tannery wastewater, etc.) and has environmental protection effects.
5.After Paecilomyces lilacinus contacted with the egg sac of nematode, in the viscous matrix, the hypha of biocontrol bacteria surrounded the whole egg, and the end of the hypha became thick. The surface layer of the egg shell was broken due to the activity of exogenous metabolites and fungal chitinase, and then fungi invaded and replaced it. At the same time, it secretes toxins to kill nematodes.
Bacillus thuringiensis
![](../../static/picture/11.jpg)
Insecticidal (including root knot nematodes, the best effect on arthropods such as Lepidoptera)
Bacillus thuringiensis can be used as a low toxicity insecticide of microbial origin, mainly for stomach toxicity. The bacteria can produce two kinds of toxins, endotoxin (parasporal crystal) and exotoxin, which make the pests stop feeding, and finally the pests die due to starvation, cell wall rupture, blood corruption and neurotoxicity; However, the exotoxin acts slowly, and its effect is obvious during molting and metamorphosis. These two periods are the peak of RNA (ribonucleic acid) synthesis. The exotoxin can inhibit DNA dependent RNA polymerase. The effect of this medicine is slow, and it can only take about 2 days after the insect takes it, and the effective period is about 1 day. Therefore, it should be used 2-3 days earlier than the conventional chemical agents, and the effect is better in the early stage of the insect. It is safe for fish and bees, but highly toxic to silkworm.
Bacillus thuringiensis preparation mainly has good control effect on some lepidopteran insect larvae, and can be used to control cabbage worm, rice bud worm, geometrid, pine caterpillar, tobacco green worm, corn borer, cotton bollworm, rice leaf roller, coir moth, ground tiger, etc. The insecticidal principle is that Bacillus thuringiensis is parasitized in the midgut of the host after being eaten by the insect. It grows and reproduces in a suitable alkaline environment in the gut. The crystal toxin is hydrolyzed by the protease in the gut of the insect to form a smaller subunit of toxic effect. They act on the upper skin cells of the midgut of the insect, causing intestinal paralysis, perforation, paralysis of the insect and stopping feeding. Subsequently, Bacillus thuringiensis enters the blood cavity to reproduce, causing leukaemia and leading to the death of the worm.
Bacillus thuringiensis can fully play its role when the temperature is high (above 20 ℃), so the application effect is best from July to September; The suitable period of application is generally 2-3 days earlier than that of chemical pesticides.
