The main component of microbial agents is beneficial bacteria, due to the different types of bacteria, the types of bacteria contained in them are also different. When you buy, you must choose the appropriate type of bacteria according to your needs. Today we will give you a look at the efficacy of different bacteria in the fungus.
The most widely used bacteria in microbial agents are the bacteria in the bacillus genus, including Bacillus subtilis, Bacillus macrospora, Bacillus jelly, Bacillus licheniformis and so on.
Bacillus subtilis
Non-toxic and harmless to humans and animals, does not pollute the environment, can produce a variety of antibiotics and enzymes, has a broad spectrum of antibacterial activity and strong resistance to stress. The main effects are nitrogen fixation, inhibition of pathogen growth, induction of plant defense system against pathogenic invasion, mainly control of filamentous fungi caused by plant diseases, such as wheat blight, tomato leaf mold, bean root rot, apple mold heart disease and so on.
Bacillus macrospora
In the production of microbial fertilizers, it is mainly used as a phosphate-phospholytic fertilizer, in addition, Bacillus macrosporum is a biocontrol strain with a wide bacteriostatic spectrum, and the bacteriostatic substance it produces is iizubicin, which has a stronger inhibition ability on fungal pathogens than on bacterial pathogens.
Bacillus jellyfish
Commonly known as potassium bacteria, it is a common soil bacterium in farmland. It can decompose and release a variety of nutrient elements. Promote crop nutrient absorption, produce a variety of hormones, proteins, amino acids, promote crop growth and development, enhance crop stress resistance, effectively inhibit the reproduction of harmful and pathogenic microorganisms in the soil, and significantly reduce the occurrence of a variety of soil-borne diseases.
Bacillus licheniformis
It is a Gram-positive thermophilic bacterium that is widely distributed in soil. It is easy to form a dominant microbial population on the surface and rhizosphere of soil and plants, effectively inhibiting the growth and reproduction of pathogenic bacteria with the same nutrient and spatial sites; it has strong protease, amylase and lipase activities, inhibits or kills pathogenic bacteria, activates soil nutrients, and helps plant nutrient absorption.
Bacillus thuringiensis
Including many variants of a class of crystal-producing Bacillus, the main active ingredient is one or more insecticidal crystal proteins, which have specific toxic activity against insects such as Lepidoptera, Coleoptera, Diptera, Hymenoptera, Hymenoptera, and Hypnotoptera, as well as animal and plant nematodes, ticks and other arthropods, and are not biosafety against non-targets.
Bacillus flankspores breve
It can produce a variety of antibacterial substances such as bacillus amines, peptide antibiotics, polyketone compounds and chitinase, and exhibits a wide spectrum of antibacterial activity on various bacteria and fungi, inhibiting plant pathogenic fungi; Bacillus breve strain BL-21 has phosphorus dissolving function, can improve soil available phosphorus content, degrade organophosphorus pesticides such as oxidized fruit music and water amine sulfuric acid;
Streptomyces jingyang
Streptomyces jingyang is a kind of actinomycetes, whose metabolic activities can promote the decomposition of organic matter, make nutrients effective, stimulate the growth of crops, and at the same time release antibacterial substances, and its metabolites also have certain anti-insect properties.
