Bacillus Pumilus

Mode of Action

• Produces antimicrobial compounds such as bacillomycin and surfactin that can inhibit the growth of these pathogens, such as Fusarium oxysporum, Rhizoctonia solani, and Phytophthora infestans. it can also compete with pathogens for nutrients and space, which can limit their growth and spread.
• Secrete enzymes such as cellulase and chitinase that can break down organic matter in the soil, which releases nutrients such as nitrogen, phosphorus, and potassium. It can also produce polysaccharides that help to bind soil particles together, improving soil structure and water retention.
• Secrete plant compounds such as indole acetic acid (IAA) and gibberellins that can stimulate plant growth and development. Act as root growth biologic fertilizer to promote nutrient uptake, while gibberellins can promote stem elongation and fruit development.
• Prevent pathogens from infecting the seedling by forming a protective biofilm around the seed, also produce enzymes that can break down the seed coat, allowing the seed to germinate more easily.

Benefit

• Improves plant growth and development
• Enhances nutrient uptake and availability
• Suppresses soil-borne plant diseases
• Enhances soil fertility and overall soil health
• Increases crop yields and quality
• Increases plant resistance to environmental stresses such as drought and salinity
• Avoid the soil problem by continuous cropping, improve the utilization ratio of bio fertilizers

Application Rate

Bacillus pumilus powder can be applied in agriculture through various methods as following:

• Seedling treatment: Mix 100 gram with an appropriate amount of water and organic manure to form a slurry. The seedlings are dipped in this slurry for 30 minutes prior to planting to promote root growth and enhance nutrient uptake as biologic fertilizer.
• Soil application: Apply at a rate of 2-3 kg per hectare via irrigation, broadcasting, or banding. The best timing of application is 3 days before or when plantation for disease prevention or control
• Foliar application: Applied 2-3 mg per liter of water via foliar spray against foliar diseases.
• Root drench: Apply at a rate of 2-3 kg per hectare to the root zone of plants, through irrigation or other application equipment.
• Repeat application at intervals of  30 days. Suggest to used together with other bacteria and fungi, likes Trichoderma spp, Pseudomonas spp, Mycorrhizal fungi, Bacillus spp ,to enhance the synergistic effect, leading to better suppression of pathogens
• Bacillus pumilus powder Thrives in a range of soil types but prefers well-drained soils with a neutral to slightly alkaline pH range (pH 6.5-8.5). Optimal growth and activity may occur at moderate temperatures (20-30°C) and moderate to high humidity levels.
