Bacillus firmus is a new type of biological pesticide derived from microorganisms. After the root is injected with Bacillus firmus, the live spores of Bacillus Firmus multiply in the soil of the root using the nutrients and water of the root, and occupy the soil around the rhizosphere of the crop rapidly, which can effectively inhibit and kill root-knot nematodes.

Bacteria count :20 billion cfu/g water soluble powder .

1. Spores of Bacillus firmus around crop roots, produce mycelium and act on root-knot nematodes, producing a variety of metabolic substances to effectively inhibit or kill the growth and reproduction of root-knot nematodes, resulting in the death of nematodes.

2. Through spore germination of Bacillus firmus, mycelium is produced to parasite the eggs of root-knot nematodes, making the eggs unable to hatch and reproduce.

Main uses:

For seed treatment or soil treatment during transplanting to control root-pathogenic nematodes in plants such as tobacco, vegetables, fruit trees and ornamentals, as well as crops such as cotton, peanuts, soybeans, sunflowers, alfalfa, corn and sorghum.

How to use:

Bacillus firmus, a member of the Bacillus genus in the family Bacillaceae, is a gram-positive, rod-shaped bacterium. It is renowned for its robustness and ability to form spores, making it highly resilient in various environments. This species was first described by Bredemann and Werner, and has since garnered attention for its potential applications in agriculture and biocontrol.

One of the standout features of Bacillus firmus is its antagonistic properties against nematodes. The strain I-1582, in particular, has been extensively studied for its efficacy in combating root-knot nematodes. These microbes can degrade nematode eggs and establish themselves at the plant roots, thereby inducing systemic resistance in plants. Such capabilities make Bacillus firmus a promising candidate for biological control strategies aimed at protecting crops from soil-borne pests.

The optimal growth temperature for Bacillus firmus is around 35°C, but it remains effective across a broad temperature range. This flexibility allows it to thrive in diverse climatic conditions, enhancing its utility as a biocontrol agent. Additionally, like other members of the Bacillus genus, Bacillus firmus can be either strictly aerobic or facultatively anaerobic, depending on environmental oxygen levels.

Bacillus firmus holds significant promise in sustainable agriculture due to its ability to enhance plant health while reducing reliance on chemical pesticides. Its role in promoting plant immunity and controlling nematode populations underscores its importance in modern agricultural practices.
