Microsporidia are obligate parasitic unicellular protozoa that can develop and divide in tissue cells, reproduce indefinitely, and are infectious.
Microsporidia proliferate in large numbers in the host cells, gradually replace the host cytoplasm, severely damage the endoplasmic reticulum, mitochondria, and nucleus of the host cells, severely damage the metabolic function of the cells, and eventually lead to cell fragmentation and death.
The “plant-Trichoderma-pathogen” triangle is a complex network of numerous processes. Trichoderma, a non-toxic opportunistic plant symbiont, is a low-cost, highly effective, eco-friendly biocontrol agent.
They can establish In various pathological systems, with minimal impact on soil balance and without damage to organisms that contribute to the control of pathogens, this symbiotic relationship results in plants acquiring resistance to pathogens, improving developmental processes and yields, and facilitating nutrient uptake and fertilizers Efficiency of utilization.
Antagonism, competition, and parasitism are the main features that prevent development in response to the presence of other competing pathogens.
Also include biosynthesis and stimulation of targeted metabolites such as plant growth regulators, enzymes, siderophores, antibiotics, etc. .

Bactericides are one of the main types of microbial bactericides, and they are also the most widely used microbial bactericides.
At present, the active ingredients in the bacterial fungicides registered in my country mainly include Pseudomonas fluorescens, Bacillus subtilis, Bacillus amyloliquefaciens and Bacillus cereus, etc.
Most of them are Bacillus subtilis Ingredients of fungicides. Fungicides containing Bacillus subtilis have been approved for registration, and these products can be used to control diseases such as tomato gray mold, rice blast, wheat powdery mildew, citrus green mold, tobacco black shank and cabbage soft rot. Studies have found that Bacillus subtilis can secrete antibiotics, cell wall degrading enzymes, chitinase and other substances to inhibit the germination of pathogenic fungal spores and the growth of hyphae. Substances digest mycelia, dissolve spore cell walls, etc.
A number of Bacillus strain resources have been found so far, and these strains can effectively control rapeseed clubroot, potato black shank, wheat head blight, cucumber corynesporium leaf spot, cucumber anthracnose, sweet potato stem rot, and tomato rot. Leaf spot and tomato powdery mildew etc.
Viral insecticides mainly cause pathogenic or lethal effects on insects through the life activities of viruses. The active ingredients of viral insecticides with a long history of research in my country include nuclear polyhedrosis virus, NPV, and granular Virus Granulosis virus and Reoviridae cytoplasmic polyhedrosis virus Cytoplasmic polyhedrosis virus, CPV.
Main nuclear polyhedrosis virus are including Helicoverpa armigera NPV and Spodoptera exigua NPV, Spodoptera litura NPV, Autographa californica NPV, Mamestra brassicae NPV, etc. are the most diverse types of viral insecticides, Control various agricultural pests such as beet armyworm, cotton bollworm, tobacco budworm Heliothis assault Guenee, rice leaf roller, corn borer and cutworm Agrotis sp.; and insecticides with granular virus and cytoplasmic polyhedrosis virus as active ingredients There are 6 and 3 species respectively, and the main control targets are diamondback moth, Pieris rapae, rice leaf roller and pine caterpillar.
Bacterial Insecticides mainly refer to microbial pesticides that use certain insecticidal bacteria to achieve disease-causing or lethal effects on various pests.
The main active ingredients are Bacillus thuringiensis (Bt), Empedobacter brevis and Bacillus sphaericus, etc. , These bacteria can secrete toxin proteins, affecting the growth and development of pests.
Fungal insecticides are the most widely used type of microbial insecticides except bacterial insecticides.
At present, the active ingredients of fungal insecticides mainly include Beauveria bassiana, Metarhizium anisopliae and Paecilomyces lilacinus, etc.
These fungi are highly infective, the insecticidal effect can be achieved through mycelium invasion of insects, enzymatic hydrolysis, and inhibition of insect immunity.
Root-knot nematode is a highly specialized omnivorous crop parasitic nematode. It mainly damages the roots of various vegetables, showing that the lateral roots and fibrous roots are more than normal, and forms spherical or conical white nodules of different sizes on the fibrous roots of young roots, and some are bead-shaped.
The aboveground part of the damaged plant grows short and slow, with abnormal leaf color, few fruits, low yield, and even premature death of the plant.
Root-knot nematodes are serious damage to crops, ranging from reduced yields to severe crop failures, so they must be controlled in time.
Lin chemical solution for root-knot nematode:
After the virus infects the target pest, it will replicate in its body.
After the pest is killed, it will infect other target pests again, which can continuously reduce the number of pests.
The virus production process does not produce pollution and consumes low energy.
An insect is a virus production factory.

Seed treatment-Promote seed enzyme activity and increase germination rate.
Foliar spray-Improve photosynthesis, green leaves increase.
Flower bud differentiation, flower bud stage use-Preserve flowers and fruits, increase the rate of booting and seed setting.
Use during fruit expansion-Puffing and coloring, improving quality.
Anti-stress & drug damage
Promote cell division and fruit enlargement. It can obviously promote the division of cells, and promote the horizontal and vertical growth of organs, thus playing the role of expanding the fruit.
Delay leaf senescence, keep green for a long time, strengthen chlorophyll synthesis, improve photosynthesis, and promote leaf color to deepen and turn green.
Breaking the dominance of the top, promoting the germination of side buds, can penetrate the differentiation of buds, promote the formation of side branches, increase the number of branches, increase the number of flowers, improve the fertilization of pollen, thereby increasing the number of fruits and increasing the yield.
Improve the quality of crops and increase their commerciality. Induce parthenocarpy, stimulate ovary expansion, prevent flower and fruit drop, promote protein synthesis, increase sugar content, etc.
