Bacillus pumilus | 8×10¹¹ CFU/g Broad-Spectrum Biocontrol & Plant Growth Promoter
Our ISO9001-certified Bacillus pumilus strain is a fourth-generation multifunctional microbial agent, containing ≥8×10¹¹ CFU/g active spores and plant-derived signal molecule carriers, achieving synergistic effects of disease control and crop growth promotion:
● Broad-spectrum antibacterial: inhibits 23 plant pathogens (inhibition zone diameter＞15mm).
● Systemic resistance induction: upregulates PR protein expression by 300-800%.
● Root development: lateral root density increased by 170% (IAA production 48μg/mL).
● Metabolic activation: Rubisco enzyme activity in leaves increased by 65%.
