Polymyxobacterin

Biological Shield for Intensive Crop Production

"Polymyxobacterin" is a development by the Institute of Agricultural Microbiology that shifts plant protection from chemical aggression to microbiological control. The active ingredient is a strain of Paenibacillus polymyxa bacteria, which possesses powerful fungicidal and bactericidal properties.

When to Integrate into the Tech Map

Agronomists select this biopesticide for specific phytosanitary challenges:

• Seed Treatment: Creating a protective zone around the seed. This is critical when sowing in cold soil, where slow germination leaves seeds vulnerable to soil-borne pathogens causing fusarium and helminthosporium rots.
• Minimizing Bacteriosis: The preparation suppresses phytopathogenic bacteria that frequently infest sunflower and sugar beet at the 2–4 true leaf stage.
• Root System Health: The bacteria colonize the rhizosphere, restricting niche space for pathogenic fungi. This directly affects the seedling survival rate of cereals and flax.

Practical Application Insights

The product is available in aqueous solution and powder forms, allowing for easy adaptation to existing seed treatment equipment. Classified as hazard class 4, "Polymyxobacterin" requires no special storage conditions or rigorous protective measures during handling. Unlike harsh synthetic fungicides, it does not induce seedling stress, making it suitable for weakened crops. A key operational tip: maximum efficacy is achieved when used with stickers (adjuvants) that fix the bacterial mass on the seed surface or vegetative parts of the plants.
