Bacillus amyloliquefaciens and its secretions have significant antagonistic effects on various pathogenic bacteria that cause root rot of fruits and vegetables, and can effectively prevent and control root rot of fruits and vegetables.


Soak the fruit and vegetable seedlings in the bacterial solution prepared by Bacillus amyloliquefaciens with a concentration of 0.5 × 109 ~ 1.5 × 109 cfu/mL for 5 ~ 15 minutes before planting, and at the same time 18 ~ 22 days after planting the fruit and vegetable seedlings with a concentration of 0.5 × 109~1.5×109cfu/mL of Bacillus amyloliquefaciens by irrigating the roots once, and the dosage of 8~12L/hm2 was appropriate.

The field control effect test results showed that the control effect of Bacillus amyloliquefaciens on cucumber root rot was 56.29%, the control effect on tomato root rot was 66.75%, and the control effect on strawberry root rot was 74.17%.

The effect is remarkable.

LIN-MA : Metarhizium anisopliae

  • WHAT’S lin-ma?

    Lin-MA (METARHIZIUM ANISOPLIAE) The active ingredient of the product is an insecticidal fungi-metarhizium anisopliae. Selected from among over 1,000 strains, the strain attains much broader spectrum, better stability and compatibility, it is a newgeneration of more efficient fungal pesticide. It can infest most species of insect pests and friendly to dragonflies and other natural enemies.

    INSECTICIDAL MECHANISM OF LIN-MA

    The effective component of Metarhizium is conidium. Conidia adhere to the pest, then the hyphae invade and grow rapidly in the pest body, invading various tissue through blood and lymph circulation.

    Toxins are secreted, effecting the pest’s central nervous system and destroying the integrity of the cell structure. Consequently, the pest will die because of tissue dehydration.

    The hyphae in dead pests can extend out of the body and produce conidia. Conidia continue to infect other insects through contact infection or wind diffusion, causing repeated infections in pest population.

    In general, when some of the pests are infected, more and more their family members and friends will be easily brought under control.
    Main formulations:

    2×10 8 spores/g GR

    8×10 9 spores/g WP

    8×10 9 spores/ml OD

Bacillus amyloliquefaciens strain for preventing and controlling root rot of fruits and vegetables

by Master, posted in Bacillus amyloliquefaciens

Bacillus amyloliquefaciens strain for preventing and controlling root rot of fruits and vegetables and its application.

The strain has a significant antagonistic effect on common pathogens that cause root rot of fruits and vegetables, especially for strawberry root rot, and has a strong ability to produce 3-indoleacetic acid (IAA) and siderophos. It can not only effectively prevent and cure root rot of fruits and vegetables, but also promote the absorption of nutrients by plants and promote plant growth.

Why Bacillus amyloliquefaciens?

by Master, posted in Bacillus amyloliquefaciens

The most suitable growth temperature for Bacillus amyloliquefaciens is 28-37 ℃.
Bacillus amyloliquefaciens is widely distributed in nature, not only can exist in soil, plant rhizosphere surface, deep sea water and the external environment, but also common in plants.
Bacillus amyloliquefaciens is non-toxic and harmless to humans and animals, and does not pollute the environment.
Bacillus amyloliquefaciens has abundant metabolites, has broad-spectrum antibacterial activity, strong resistance to stress, fast growth and good stability.

Merits of Bacillus amyloliquefaciens

by Master, posted in Bacillus amyloliquefaciens

The growth and metabolism of Bacillus amyloliquefaciens produces active substances such as low molecular weight antibiotics and antibacterial protein polypeptides, which can inhibit pathogenic bacteria and nematodes; the active substances of most metabolites are thermally stable, insensitive to ultraviolet irradiation and protease treatment, and have acid and alkali resistance, etc.

What Bacillus amyloliquefaciens can do?

by Master, posted in Uncategorized

Bacillus amyloliquefaciens can produce low molecular weight antibiotics, antibacterial proteins or polypeptides and other active substances in the process of growth and reproduction, and can simulate tomato leaf mold, early blight, gray mold; cucumber, melon fusarium wilt, anthracnose, pepper late blight and other harmful bacteria.

By metabolizing cellulase, protease and small molecular organic acid, Bacillus amyloliquefaciens can decompose soil organic matter, activate insoluble phosphorus and potassium and other potential nutrients, improve crop rhizosphere micro-ecological environment, and improve soil fertility.

Bacillus amyloliquefaciens can induce plants to secrete endogenous hormones rapidly such as gibberellin, indole acetic acid, cytokinin, etc., promote plant root growth, and enhance plant disease resistance.
